10403716114 Inline Fuel Injection Pump for 1006TAG Engines

The application we stand behind is the Foton Lovol 1006TAG, also written 1006TAG02: a six cylinder inline diesel rated at 121 kW, turbocharged and air to air intercooled, built for generator sets and industrial plant. Two numbers carry that application and they are worth checking against your machine before anything else, because they are the ones the published data actually supports: six cylinders and the engine power rating above. On a genset package the nameplate gives you both, usually alongside a rated output in kilovolt-amperes rather than kilowatts, and the conversion back to engine kilowatts is straightforward. That is the diesel injection pump the engine was built with, and an order that starts from the number on the removed unit is the one that arrives correct.

Why the removed pump matters more than the model list. The CPES designation series runs several variants across emissions revisions and output ratings, and two machines with the same model badge can take different parts. The data plate and the actuator arrangement on the old unit are the ground truth: they carry the pump number and the governing variant, and they survive long after the paperwork is gone. Match that, then count the delivery valves, then check the actuators, then order. A six cylinder inline injection pump bought this way arrives correct the first time, which is the whole point of the five steps above.

What this page is not claiming. We are not saying that any neighbouring designation fits, that a component number for the cam or the feed pump internals is settled, that the published application covers a machine without a plate check, or that a pump from another engine family will substitute. 10403716114 is the pump published for the 1006TAG 1006TAG02 121 kW six cylinder diesel, and T73208233 describes the same unit on those machines. 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 diesel engine with an inline injection system keeps the low pressure and high pressure sides in one casting. Fuel arrives at the inline fuel injection pump at feed pressure, an internal feed and transfer arrangement raises it, and the cam lobe acting on each pumping element forces a metered charge up that cylinder’s delivery line. Because the pressure is generated inside the body and the cam decides the timing, the assembly either pressurises all six cylinders consistently or it does not. On this particular unit the delivery bank is visible from the outside: six valve holders in a row, each closed with a green cap, one per cylinder.

The naming is where most ordering mistakes start. The words fuel injection pump, diesel injection pump and inline injection pump describe a family of parts built on the same idea across very different engines, not one unit. Within the CPES designation series the number that follows the mounting class carries the cylinder count and the plunger bore, and neighbouring designations do not substitute for one another. What makes a unit the 10403716114 pump for your machine is the combination of number, valve count, actuator arrangement and engine plate — which is why this page anchors on the number and treats everything else as reference rather than promise.

On a six cylinder engine the diesel fuel injection circuit is one shared path: one pump, six pumping elements, six delivery lines. That is what an inline injection system means in practice — pressure is raised centrally and the cam meters each cylinder in turn — and it explains the split you can diagnose with: a supply-side fault such as a tired feed pump or a blocked filter drags every cylinder down together, while a single worn pumping element shows up on one cylinder and leaves the rest steady. That distinction is worth more than any guess, because the two causes cost very different amounts.

The governing arrangement is the part that catches people out on this family. A conventional inline pump meters through a mechanical lever and sector linkage, and a workshop swapping one of those for a unit with electric actuators has changed the part, not just the age of it. The 10403716114 unit carries two flat electric actuator modules stacked on the actuator end, one above the other, and the presence of that pair is visible in the photographs. Their control voltage and set points are not published for this number, so we will not guess at them; what we can do is confirm the modules are there, and confirm the variant is right for your application once we have the engine plate.

When the pump stops behaving, the engine tells you through how it runs rather than through a warning light. A hard start that clears once warm. Smoke that stays once the engine is hot and working. An idle that hunts and will not settle. Each of these is examined properly in the symptoms section below, together with the delivery line comparison that finds the guilty cylinder without guesswork.

Where our supply differs is what arrives. Original equipment supply comes through the manufacturer’s own channels, and a buyer who needs a factory boxed part does need to go there. What we supply is an inline pump replacement — a new compatible unit for the same job, sold under the Vidishi Auto brand, carrying the same published number and designation format, at a single-piece minimum with no core return. That last point matters on a diesel job: nothing has to come back, there is no exchange loop to manage, and the old pump stays with you for the parts shelf or the warranty file.

One thing we do not do is dress that up. The 10403716114 pump we ship is ours, not a manufacturer’s and not an equipment maker’s. The part number, the type designation and the OE cross reference appear on this page so you can match the pump you are replacing. They are references for fitment, not a claim about who made the part. 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 read directly from the goods we handle, including the black data plate, the cast marking on the machined boss and the delivery valve count. Reference means a part number, a published type 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 delivery figure or a component number that we cannot source would be worse than an empty cell, because it would end up in someone’s parts order.

What is in the box. One complete inline fuel injection pump: the cast body with its six pumping elements and delivery valves behind the capped holders, the feed pump mounting, the drive end, and the pair of electric actuator modules on the actuator end, exactly as photographed. A fresh sealing washer goes under every refitted pump, and no separate seal kit is asserted for this line. Nothing on this page is sold loose from the pump, and internal service components keep their own listings for buyers who want a rebuild rather than a replacement.

Read the table from the top. 10403716114 is the part number and it is the one that matters on the part itself: it is what the data plate on the supplied unit carries, and it is the number the parts catalogues list first. The grouped form, 10 403 716 114, is the same number written with spaces the way it is stamped, and a parts system will match one form and not the other, which is worth knowing before a search box tells you a part does not exist. As a 10403716114 cross reference, the table is a boundary as much as a bridge.

The T73208233 row is the second half of the mapping, and it is the one to read carefully. Published cross reference data gives T73208233, written T73208233 without spaces, as the OE number the equipment side of the trade uses, attributed to the Foton Lovol 1006TAG 1006TAG02 121 kW six-cylinder diesel. That is the application we publish on this page and the only one. The point of the row is that a buyer holding the part number, a buyer holding the OE number and a buyer holding the pump itself can be told, in one line, that they are asking for the same unit.

The designation row is the third layer, and it is the one that carries engineering information rather than identity. CPES6PB110D120RS3164 states the mounting class, the cylinder count, the plunger bore in tenths of a millimetre, the design version, the feed pump and governor layout and an application run code; PB6 114A is the published short form of the same designation. These are reference values, quoted so that a workshop comparing a used pump against a catalogue line is comparing like with like.

What the table deliberately does not do is extend itself. It does not say that a neighbouring designation fits, that a component number for the cam or the feed pump internals is settled, or that a pump from another engine family substitutes. 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. If you are holding a number that is not on this list, send it to us with the engine plate and we will tell you what it is and whether it is this pump.

The practical difference shows up on the delivery line bench. When one cylinder’s return volume is climbing, the machine either runs on a compromised cylinder until something else breaks, or the workshop fits a known-good pump and the fault disappears. Keeping a matched spare — correct number, correct valve count, correct actuator variant — turns a two-week machine stop into a same-week 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 set where a single repair, not a warehouse, is the unit of purchase.

• Hard starting, worse when warmA pump whose delivery valves no longer seal will let pressure bleed back, and the engine has to crank longer before it catches. A start that is fine cold and slow hot is a classic pump signature.
• Black or grey smoke under loadFuel that is not atomised properly leaves the stack as smoke. On an inline pump this usually points at a worn pumping element or a delivery valve that is not seating.
• An idle that hunts or will not settleAt idle each of the six cylinders counts and the cam is metering all of them. A pump worn enough to deliver unevenly shows up as an idle that will not hold, often with a shake no mounting fault explains.
• Loss of power when the engine is workedWhen the operator demands fuel, a pump that cannot hold its internal pressure cannot deliver the full charge, and the machine feels flat exactly when it is asked for more.
• Rising fuel consumptionFuel that returns past a worn delivery valve is pumped again and again, so the gauge moves faster than the work done and the tank empties sooner than the hour meter suggests.
• A delivery volume that stands outThe measurement that settles it. Comparing return volumes line by line shows the cylinder whose internal sealing has gone, before any part is ordered.
• A rough engine that no filter work curesFilters and injectors are the usual suspects on a diesel, so a pump fault is often diagnosed late. If the fault returns after a filter and an injector swap, measure the delivery lines.

Read the list as symptoms rather than a diagnosis, because every item on it has at least one other possible cause. A tired feed pump or a blocked filter produces the same hard starting. A boost leak produces smoke and flat response without the injection pump being at fault. What separates them is measurement: delivery volumes compared line by line while the engine idles, then a look at the fuel supply and the feed pump side. A cylinder returning clearly more than its neighbours points at the pumping element inside the pump; a low reading across all six together points at the supply or the feed pump instead. Those two causes cost very different amounts, which is why the measurement is worth doing before a part is ordered.

Two more practical notes. If the machine has recently had fuel system work, look there first: a delivery union left slightly proud, an air lock in the line, or a drive coupling fitted a tooth out of position will produce exactly the symptoms above, and none of them need a new pump. And treat one bad pump as a question about the others: they are the same age and they have drunk the same fuel, so a fleet that replaces one usually budgets for the rest. A diesel injection pump found early is a cheap part; the same pump found late, after unburned fuel has washed the cylinder walls, is an engine discussion.

1. 1. Release the pressure and mark the couplingLet the engine stand, release residual pressure, and before anything is unbolted mark the position of the drive coupling against the pump body. An inline pump must go back on the same timing position, and the mark is the only thing that guarantees it.
2. 2. Clean the mounting face before it is openedWash around the pump, blow the sealing face down, and only then release the bolts. Grit that falls onto the sealing face ends up between the faces, and the new pump will weep from its first minute.
3. 3. Unbolt evenly and support the bodyWork the bolts in sequence rather than freeing one corner at a time. The pump is a heavy casting and the mounting face has to lift straight off the engine, not at an angle.
4. 4. Inspect the drive end and the couplingCheck the coupling face, the slot and the drive for wear and burrs. A coupling that has been turning against a worn drive will damage the new pump in the first hour of running.
5. 5. Fit fresh sealing washersA fresh washer goes under every refitted pump, and the delivery line seals are renewed rather than reused. Reused seals are the most common cause of a weep after an otherwise correct pump replacement.
6. 6. Refit square and torque to the engine figureDrop the pump into the marked position, bring the mount up evenly, and torque to the figure for your engine. The figure belongs to the machine, not to the part, and the clamp load is what keeps the timing position true.
7. 7. Seat the actuator connectors and route the harnessThis unit applies its governing function through the two electric actuator modules, so both connectors must be fully seated and the harness routed clear of the hot side of the engine. A pump swapped from a mechanically governed variant will not behave the same way even if it bolts on.
8. 8. Refill, bleed and prime the system properlyThe pump will not lift immediately on a dry system. Fill and bleed according to the procedure for your engine, and run the feed side to prime before the first start rather than cranking a dry pump against its own seals.
9. 9. Verify with a delivery line check and a running checkStart the engine, check for leaks at the unions, the mount and the actuator connectors, then measure each delivery line in turn. Where a doubt remains, a running check confirms the machine is back on its feet.

Every 10403716114 pump 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 water in the system, from incorrect fitting, from a drive coupling torqued beyond its figure, or from a separate fault elsewhere in the fuel circuit. It is a supplier warranty from Vidishi Auto, and we are not a dealer for any of the equipment makers, so no cover from any of them travels with this part.

The cover sits at unit level. It applies to the pump as supplied, and it does not extend to the engine, to the machine, to labour, or to another component damaged when a faulty unit was run on. That boundary is normal for a fuel system part, and it is worth stating before the order rather than after a problem.

Two questions buyers ask. The 10403716114 warranty starts from delivery rather than from fitting, so a pump held on the shelf as a diagnostic spare is still covered for the stated term from the date it reached you. And because there is no core return with our supply, the warranty is not tied to an exchange claim: the old pump stays yours, and what you do with it has no effect on the cover on the new one.

The minimum order quantity is 1 piece, which is deliberate. A single unit covers a single machine repair, and it means a workshop can test the fitment on one engine before committing to a fleet order. From there the line scales normally — a plant running several engines will take one per machine, and a distributor will take them alongside the rest of a fuel system order on one set of export documents.

We act as a diesel injection supplier for export and we build this line ourselves as the manufacturer behind the Vidishi Auto brand. Pump pricing is quoted per order rather than published as a fixed figure, because pricing moves with quantity and with what else is on the same shipment, which is how fuel injection pump wholesale normally works. Mixed orders are routine on our side: put these pumps alongside filters, lines or other engine lines and they travel on the same paperwork.

For trade buyers, two practical points about a pump line. First, because there is no core return and no core charge, procurement does not carry a returns loop on top of the order itself — the part of buying fuel system parts that usually costs the most administration simply disappears. Second, batch consistency matters to resale: our batches ship from one production run with uniform data plates and a consistent actuator arrangement, so your stock photographs and your counter claims stay honest. If you need the number matched against a machine list before you commit, send the list with the engine plates and we will work through it with you rather than asking you to take the fitment on trust.

Batch photographs are part of the offer rather than a favour. What leaves our floor is one production run with uniform data plates, and the picture below shows the actuator end as it is counted before packing — the same modules, the same plate format, the same finish on every pump in the batch. A distributor who sells against a photograph can only do that honestly if the stock really does look like the photograph.

Distributors serving plant and genset fleets will also find this line sits cleanly beside the wider fuel system range on this site. A parts distributor holding this number against an enquiry can quote from this page without waiting for us, and every unit that ships carries the same data plate and the same actuator arrangement shown in the photographs above. Ordering questions of any kind go to the same team that confirms fitment, which you can reach through the contact page or the help centre.

The dimensions above are a packing estimate for a single boxed pump, and we label them that way deliberately. No source we can stand behind publishes a packaged size or a gross weight for this number, so we give you a figure we can pack and weigh against rather than a manufacturer specification we cannot evidence. For the same reason we do not list an unpackaged pump size or an unpackaged pump weight. Lead time is quoted per order and depends on quantity and on what else is on the same shipment. For export shipping of fuel system parts, every order leaves with its paperwork in place — commercial invoice, packing list and HS code. Read our shipping information for freight options, and our help centre answers the ordering and documentation questions that come up most.

A trade order is packed the way the photograph shows it: the actuator end and the delivery valve bank are the two areas that decide whether a pump survives the journey, so both are protected before the carton closes. A damaged actuator mount or a knocked-over valve holder is what turns a cheap part into a second removal job, because the pump will not seat or seal against a face that has been moved. If your receiving process needs a different pack — labelled per machine, split per engine or boxed for retail — say so at quote stage and we pack to it.

An injection pump is a small number of large, precisely machined parts, so this line is checked at unit level rather than by sample. Every batch passes an incoming check for the black data plate and the cast marking on the machined boss, an inspection of the drive end and the delivery valve bank, a confirm that the sealing faces are clean and undamaged, a check that the drive turns freely and the actuator modules are correctly fastened and plumbed, and a packed-weight confirmation against the documented figure. The supplier shows an ISO 9001:2015 system certification badge on the product photography, which is recorded here as a supplier statement rather than as a certificate we issue. Rather than publish reviews we cannot verify, we tell you how the part is inspected and let your own delivery line bench be the judge.

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 number read off the pump you are removing, the machine details and a photograph of the engine code plate, 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 CPES designation series runs several variants across output ratings and governing arrangements. Support continues after delivery: fitting questions, actuator connection questions and warranty claims all reach the same team, and the person who confirmed your fitment is the person who answers if something is not right.
