T73208261 Governor CRSV350/750PB0C196R for 1006TG02 Diesel

The application we stand behind is the Perkins and Lovol 1006TG02, published also as the 1006TG2A, a six cylinder diesel rated at 92.3 kW, with the governor paired in the published record to pump model CPES6PB110D120RS3162, a PB type inline pump under pump number 10 403 576 112. Two things carry that application and they are the ones the published data actually supports: the six cylinder PB type inline pump, and the pair of numbers on the governor itself. That is the mechanical fuel pump governor this engine was built with, and an order that starts from the pump the governor came off is the one that arrives correct.

Why the number this listing was found under is not enough. T73208261 is published by the engine maker against a fuel pump on this platform. That is a real number on a real part, but it is a pump number rather than a governor number, so a search on it lands on the wrong category of part. We keep the number visible on this page because it tells you which engine family the listing came from, and because a buyer who already has it in hand needs to be told what it is. But the identifiers that identify the assembly in front of you are CRSV350/750PB0C196R and 10 421 535 096, and those are what we match against the unit you send us.

Two more identifiers worth having. If the machine is still with the customer, the serial number on the registration or the serial plate settles the engine variant faster than any chart, and the build plate number settles which build the machine left the factory as. Where the governor is already off the machine, a photograph of the engine code plate and a photograph of the model and part number on the governor itself settle it instead. Any one of those three alongside the pair on the governor is enough for us to confirm in writing; all of them together is what stops a number mix-up reaching your workshop.

What this page is not claiming. We are not saying that a neighbouring number in the same series fits your pump, that the governor covering a different pump family substitutes, that the speed range or droop figures for this number are settled, or that a governor is fitted without a bench setting. CRSV350/750PB0C196R describes one build for one pump family, and the two numbers on the unit plus the pump model are what identify it. Anything beyond those lines is better answered from your own parts data, and we would rather answer it with you than assert it here.

A mechanical injection system has two halves that work together and fail differently. The pumping half delivers fuel: the plunger and pumping element in each cylinder sleeve sweeps down its bore and forces fuel up to delivery pressure, and the delivery valve closes at the end of the stroke to seal it in. The control half decides how much of that the engine is allowed to take, and it is the part on this page. The injection pump governor is the device that watches engine speed and moves the fuel rack to hold the engine at the speed it was set to. Both halves live on the same pump body, and a fault in either half feels different from the driver seat, which is why telling them apart is worth doing properly.

The mechanism is older than electronic engine management and it is still the right answer where a machine has to hold a speed without a control unit to talk to. The pump shaft turns a splined drive stub in the governor. A centrifugal sensing element inside the top cover responds to how fast that shaft is turning, pushing against a spring whose force is set once on a bench. The balance between the two moves a linkage, and that linkage works through an external lever onto the fuel rack. Load comes on and the engine tends to slow; the rack is moved and the fuel goes back up; the engine recovers and the rack is eased off again. That loop runs continuously, which is why a governor wears out as a speed-control failure rather than as a fuel-metering failure.

The naming is where most ordering mistakes start on a part like this, and the mistake has a specific shape. T73208261 is published by the engine maker against a fuel pump on this platform, so a straightforward lookup hands you a pump and a supplier who reads that wording can offer you the wrong assembly entirely. The physical answer is visible on the part, and it is the same answer whichever number you searched: a governor presents a shaft end face carrying a drive stub seated in a bore, an external linkage lever standing off the side, and a mounting bracket that bolts to a prepared face on the pump. A pump has none of those. That is why the five steps in the fitment section start at the drive end and not at the description.

The second thing worth knowing is what a governor is not. It is not the pump body, it is not the plunger and pumping element, it is not the delivery valve, it is not the feed pump that supplies it, it is not the drive gear or the timing gear that turns the whole assembly, and it is certainly not the injector at the other end of the line. A governor alone is not a working injection pump, and a listing that does not say so is a listing that will disappoint somebody. This one says so in the box contents, in the summary and in the questions below.

When the governor stops behaving, the engine tells you through how it runs rather than through a warning light. A speed that hunts and will not settle. An idle that will not come down. A set speed that has crept upward over the months. Each of these is examined properly in the symptoms section below, together with the bench check that separates governor work from pump work without guesswork.

Where our supply differs is what arrives rather than how the part works. Original equipment supply comes through the manufacturer’s own channels, and a buyer whose paperwork requires a factory sealed part does need to go there. What we supply is a governor replacement — a new compatible assembly for the same job, sold under the Vidishi Auto brand, published under the same model and part number, at a single-piece minimum with no core return. That last point matters on a governor job more than on almost anything else: nothing has to come back, there is no exchange loop to manage, and the removed governor stays with you for the warranty file.

One thing we do not do is dress that up. The T73208261 governor we ship is ours, not a manufacturer’s and not an engine maker’s. The part numbers, the model designation and the manufacturer name appear on this page so you can match the governor you are replacing. They are references for fitment, not a claim about who made the part, and the marks visible in the photography are recorded as markings carried by the goods. The buying guides hold the general method for confirming any diesel part from the unit itself, and the glossary explains the terminology if any of the names above are unfamiliar.

How we label data. Confirmed means a value from the published pairing for this governor or read from the goods we handle, including the drive end, the bearing bores and the external linkage visible in the photography. Reference means a part number, a family designation or a cross reference quoted so your paperwork can be matched, and carrying no claim about origin. Not published means the field is left blank on purpose — a speed range or a lever dimension that we cannot source would be worse than an empty cell, because a governor adjusted to a figure from a product table is a machine with no speed limit.

What is in the box. One mechanical injection pump governor: the cast body with its stepped top cover and the sensing element closed inside it, the splined drive stub and its collar, the mounting bracket, the linkage lever plate with its elongated adjusting slot, the adjusting stud with its lock nut, the stop pin, and the two hex union fittings on the coupling side, as photographed. New joint material at the mounting face and at both fuel connections is required at fitting and is not asserted as included for this line. Not supplied, and not part of this listing: the pump body, the plunger and pumping element, the delivery valve, the feed pump, the drive gear, the timing gear, the pump bracket and the injector. Each of those has its own number and its own listing, and a governor fitted without them is not a working fuel system.

Read the table from the top, because the order matters and the first two rows are the ones that decide the order. CRSV350/750PB0C196R is the model designation of the assembly and 10 421 535 096 is its part number, and those two are published together for the same governor. T73208261 is on this page for a different reason: it is the supplier number for this listing and it is published by the engine maker against a fuel pump on the same platform. It identifies the platform, not this part. Used as a T73208261 cross reference map, the table is a boundary as much as a bridge — a parts system will match the governor numbers and not the pump number, which is worth knowing before a search box tells you a part does not exist.

The middle rows are the pump side of the pairing, and they are there to be read as context rather than as a claim. The pump number and the pump model tell you what this governor is published against, which is what makes the fitment question answerable at all. They identify the pump, not this part, and a buyer who needs a pump needs a pump listing rather than this one.

The last two rows are the half of the mapping that catches people out. Both are published numbers for other governors in the same or a neighbouring series, and both exist so that a buyer holding one of them can recognise what is already on their machine. Neither is interchangeable with this one. A governor is matched to one pump family through its drive stub and its external linkage, and a number from a neighbouring build may drive the linkage at a different ratio or bolt to a different face. Use those rows to identify a unit you already have, not to authorise a purchase you have not verified. If you are holding a number that is not on this list, send it to us with the pump model.

What the table deliberately does not do is extend itself. It does not say that a neighbouring number fits your pump, that a governor from another pump family substitutes, or that the speed settings for this build are settled. Those are exactly the assumptions that turn a cheap order into an expensive week of machine downtime, and we would rather leave the cell empty than fill it with a guess. Our comparison charts set out the number families we can evidence, and the buying guides cover the general method for confirming any diesel part from the unit itself.

The practical difference shows up on the bench. When a machine loses speed control and the governor will not hold its setting off the engine, the choice is to run the machine without a reliable speed limit or to fit a known-good assembly and have the fault clear itself. Keeping a matched spare — right governor model, right part number, right pump model, linkage present — turns a machine that has to be taken off site into a same-visit swap. That is the case for holding one of these on the shelf before anything has failed, and it is why the minimum order is a single piece rather than a batch: a governor is bought to fix one machine, not to stock a shelf.

• A speed that hunts and will not settle — A governor is a feedback loop, and a hunting speed means the loop is oscillating rather than settling. Wear in the sensing element, a linkage that has loosened at its pivot, or a rack that is not moving freely all produce it, and a governor that is simply out of adjustment produces a milder version of the same thing.
• An idle that will not come down — When the spring side of the balance is not strong enough against the sensing side, the set speed creeps and the idle sits high. It is easy to mistake for a pump that is delivering too much, because the symptom is the same from the driver seat.
• A speed that swings when load is applied — Load comes on, the engine dips, and it recovers slowly or overshoots before it settles. That is a governor responding but not quickly or not smoothly enough, which usually means the linkage geometry or the preload rather than the pump internals.
• A set speed that has crept upward — A governor that has lost preload lets the engine run faster than it was set to as the hours go on. This is the failure worth catching early, because the same loss of control is what removes the top speed limit.
• A stop speed that will not fall away — The lever stop position is what brings the engine down at shutdown, and when the linkage or the stop has worn the engine keeps running above the intended idle after the stop is pulled.
• No speed limit under load — This one is a safety symptom rather than a comfort one. A governor that has lost the spring side of its balance will let the speed climb when the load comes off, and that belongs on the list of things that gets a machine taken out of service rather than a note in a log.
• Speed that changes with the machine attitude — On an application where the engine can run at an angle, a governor whose linkage is binding will follow the attitude instead of the load. That points at the linkage and the mounting rather than at the sensing element.
• A fault that moves with the governor off the engine — The test that separates governor work from pump work is a bench check. If a governor taken off the engine still misbehaves on the bench it is the governor; if it behaves correctly on the bench while the engine misbehaves with it fitted, the fault is elsewhere in the fuel circuit.

The pattern worth holding on to is the one that is about speed rather than about delivery. A worn plunger or a delivery valve shows up on one cylinder and leaves the engine steady on the rest. A tired mechanical fuel pump governor shows up across the whole machine, because the governor is what every cylinder is being told to do. That single distinction does more diagnostic work than any code name, and it is why we would rather see a governor off the machine on a bench than a code decoded from a list. The fault code guide explains how to read the data behind a code, and our maintenance guide covers the filter and water separator intervals that keep a mechanical injection system healthy.

• Step 1. Mark the linkage before anything is unbolted
  Photograph the linkage before you touch it: where the lever sits, where the adjusting stud is set, and where the stop pin is. A governor is adjusted, and knowing where it was adjusted from is the difference between refitting it and losing the setting.
• Step 2. Flush the system if the pump failed internally
  If the old governor came off a pump that failed, replacing only the governor destroys the new one. Drain the lines, fit new filters, and clear the pump before the new assembly goes on. This is the single biggest cause of a second failure.
• Step 3. Clean the mounting face and the fuel connections
  Wash around the mounting face and blow the sealing surfaces down before releasing anything. Grit between the governor and the pump face weeps from the first minute, and the joint material is the cheapest part of the job.
• Step 4. Support the body and unbolt evenly
  Work the bracket bolts in sequence rather than freeing one corner at a time. The body has to come off square, and the drive stub at the shaft end must never be levered against to gain clearance.
• Step 5. Inspect the drive stub and its bush
  Check the stub, the collar and the bush in the shaft end face for wear, burrs and scoring. A stub that has been turning against a worn bush will damage the new governor within hours of running.
• Step 6. Refit the linkage without disturbing the setting
  Put the lever, the adjusting stud and the stop pin back the way you photographed them. If a part has to be replaced, treat it as a new adjustment rather than assuming the old position still holds.
• Step 7. Fit new joint material at every sealing face
  A fresh seal at the mounting face and at both fuel union connections, every time. Reused seals and reused joint material are the most common causes of both a weep and an early return of the same fault.
• Step 8. Set it on a test bench, then verify on the engine
  A governor is a calibrated device and the setting belongs on proper bench equipment against the rated speed of the engine it is fitted to. Once fitted, confirm the idle settles, that the set speed holds under load, that the load-off rise is within what the engine maker allows, and that the stop brings the engine down.

Two notes on what we deliberately do not print. We do not publish the governing speed range, the droop figure, the rack travel, or the tightening figure for the bracket, because all of them are either a bench setting or a figure belonging to the pump the governor is bolted to — and a figure copied from a product page into a workshop manual is how a machine ends up with no speed limit. Take them from the engine manual and from the bench. And we do not publish a diesel fuel injection adjustment procedure as a shortcut, because the mounting bolts, the fuel connections and the linkage setting each have their own requirement and they are not interchangeable. The installation guide covers the surrounding routine, and the glossary defines the terms if any of the above are new to you.

Every T73208261 governor is covered by a 12-month warranty against manufacturing defects. That covers a unit that arrives out of specification or fails early because of how it was made. It does not cover damage from contaminated fuel, from a pump that failed internally, from an incorrect fitting, from a drive stub torqued beyond its figure, from a bench setting that was never carried out or was carried out incorrectly, or from a separate fault elsewhere in the fuel circuit. It is a supplier warranty from Vidishi Auto and it is not a BYC warranty and not an engine maker warranty — we are not a dealer for any of the equipment makers and no cover from any of them travels with this part.

The two conditions we ask about every time are whether the system was flushed when the old governor came off, and whether the replacement was bench set after fitting. Those are the two most common reasons a new governor fails early, and both are easiest to get wrong on a job where somebody is under time pressure. Tell us what was done and we can tell you quickly whether a claim is likely to stand. If you would rather settle that question before you order, the contact page is the fastest route to a written answer.

The minimum order quantity is 1 piece, and the reasoning is worth stating rather than leaving you to work out. A governor is an individual service part rather than a bulk consumable: one machine loses speed control, one governor is ordered, one machine goes back to work. That is why one piece is the sensible purchase here rather than a workshop batch, and it is also why a single-piece line is not a signal that we do not trade in volume. From there the line scales normally — a fleet running several machines will take one per engine, and a distributor will take them alongside the rest of a fuel system order.

What we do not do on this line is pretend the part is something it is not. The unit we ship is a new compatible replacement sold under the Vidishi Auto brand. It is not BYC-branded, it is not an engine maker’s product and it is not a factory sealed original. That matters commercially as well as legally: if your incoming goods inspection needs a specific brand on the paperwork, this is not that product, and we would rather tell you now than have a delivery rejected. The help centre covers ordering and documentation questions.

The package size and gross weight in that table are a packing estimate, and we label it that way rather than quietly presenting it as a specification. No source we can stand behind publishes a packaged figure for this number, so we give you a figure we can pack and weigh against rather than a manufacturer specification we cannot evidence. If your freight is calculated on volumetric weight rather than actual weight, tell us the destination and we will confirm the chargeable weight against the carton we actually use. The shipping page sets out the full documentation and delivery terms, and the order tracking page is where to follow a shipment once it has left.

On the protective side, the two areas we watch are the splined drive stub and the linkage lever on the outside of the body. A stub knocked out of true will not drive the sensing element correctly and the governor will never hold a setting properly, and a bent lever arm is a fault that looks like a linkage problem for weeks afterwards. Both are packed protected on every unit, and both are worth checking on arrival before the box goes into stores.

A governor is a small number of precisely made parts whose whole job is to behave predictably under a spring load, so this line is checked at unit level rather than by sample. Every batch passes an incoming check on the published model and part number, an inspection of the shaft end face with its two bearing bores, a check that the splined drive stub and its collar are present and true, a confirm that the mounting bracket, the linkage lever, the adjusting stud and the stop pin are all fitted, a check that the two hex union fittings are clean and unblocked, and a packed-weight confirmation against the documented estimate. The supplier shows an ISO 9001 system certification badge on the product photography, which we record as a supplier statement rather than as a certificate we issue.

Rather than publish reviews we cannot verify, we tell you what we will actually put in writing: a written fitment confirmation against the governor numbers and pump model you send us, a written quote against your quantity and destination, and a warranty position on any claim that follows. If you need a supplier who will sign a specific inspection or conformance document with the order, ask before you buy rather than after, because the answer depends on what the document is. The help centre covers the documentation we can provide, and the partner programme page is the route for a standing arrangement that needs more than a one-off order.

Support is not an add-on on this line — it is how most of these orders get placed correctly. It costs nothing before you buy: send the model and part number read off the governor you are removing, the pump model it came off, the engine code and the machine details, and we check the whole set against what we supply before quoting. That last item is the one people skip, and it is the one that matters most here, because the number this listing was published under belongs to a pump rather than to this governor. Two minutes with the old unit in front of you is cheaper than a governor that arrives and cannot be lined up with the linkage on your pump.

Two things we will not do, whatever the order size. We will not quote a fitment we cannot evidence, and we will not ship a governor matched on a platform number when the numbers on the old unit are available. If that costs us an order, it is still the right call: a governor that arrives mismatched costs a workshop a second removal and a machine off the road for longer, and that is the failure we exist to prevent. If anything on this page is unclear, the contact page lists every route to us, and a written answer is always better than a guess on a workshop schedule.
