Product Details
0414755018 by the Numbers
Verified identity and fitment data for the complete diesel unit pump, supplied for the Liebherr D934 / D936 industrial engine.
Every item in this listing is a complete electronic unit pump assembled as one sealed body, not a nozzle or a service kit. Bosch built the family as a PLD unit pump — a single-cylinder element with an electronically controlled spill valve bolted to it — and that family name is why the assembly belongs to the unit pump system rather than to any shared-pressure layout. The Bosch PLD unit pump badge on the cover tells a fitter which bench checks apply. Buyers arrive by several routes: some read the code off the old body, some bring the Liebherr host number off a parts list, and others search by the Deutz 1013 unit pump they are replacing. All of those routes land here, because it is one physical unit carrying one interchange set.

Most buyers arrive with a single number alone, so the whole family sits on one page. Send the nameplate and we confirm the fitment before you order; the same reference doubles as a depot guide for pumps coming off a D934 or D936. Interchange numbers seen across independent sources: 0 414 755 018 / 0414755118 / 10116257 / 04262056.
Fitment verification
- Engine code plate — the plate on the block must read the D934 or D936 build, not another rating from the same family.
- Old pump nameplate — the part number and the etched line are read straight off the body so we match the unit, not just the engine.
- Flange and connector photo — the mounting face, the bolt pattern and the chassis side of the connector show which build revision the pump belongs to.
About the 0414755018 Assembly
What a single-cylinder camshaft-driven element is, and how it sits in the fuel circuit of a D934 or D936 industrial diesel.
What is a unit pump?
It is a single-cylinder, camshaft-driven high-pressure element that both pressurises and times the fuel for one cylinder. The 0414755018 is a complete unit of that kind in the Bosch PLD family: one body holding the plunger element, the return spring, the roller tappet, the spill valve and the solenoid, so nothing is left for the engine to meter separately. The name is not decorative — it describes a pump that stands on its own, unlike an element that only works as part of a larger housing.
How does a unit pump work?
The engine camshaft lifts the roller tappet, the plunger compresses the fuel trapped in the element, and the spill valve opens at the moment the control unit chooses so the pressurised fuel leaves for that cylinder’s injector instead of going back to the supply. Timing is electronic, pressure is mechanical, and the two meet inside one small body. On a D936 there are six of these elements, each trimmed individually, so a tired unit shows up as one cylinder drifting away from its neighbours long before the engine refuses to start.
Electronic unit pump explained
The principle is simple: a mechanical element with an electronic spill valve bolted to it, where the cam does the work and the control unit does the timing. Putting that beside a system that makes its pressure in one place and distributes it to every cylinder comes down to where the pressure is generated — in the individual element here, versus in a single pump feeding everything. Both are high-pressure diesel injection, but the hardware, the leak-down behaviour and the bench checks are all different, which is why the two never interchange. A pump that will not build its delivery on the bench is not cured by changing nozzles somewhere else in the circuit.
Inside this assembly sits its own plunger and delivery element in one body, which is why no separate internal component number is published for this part number. The pump is built to the Bosch 0414755018 specification, carries a 12-month warranty, and is supplied new under the Vidishi Auto brand as a compatible replacement.

Identification: part number location
The number is stamped on the pump body, the spaced form 0 414 755 018 is laser-etched on the black cover nameplate beside the code line, and the flange bolt pattern confirms the mounting. On the frame we photographed for this listing the cover line reads the later issue, which is the number most commonly printed on current production. Reading that plate against these lines is the quickest way to settle a match before ordering.
Reference figures come from the 0414755018 host-number reverse lookup together with the Liebherr 10116257 and KHD-Deutz 04262056 component evidence; the Bosch number is carried on the body as an interchange, never as an origin claim. Net weight is left as not published because no source ties a figure to this part number, so only the packaged shipping weight of 1.700 kg is stated. Pressure is a class rating rather than a per-unit calibration value, and delivery quantity, coil resistance and opening pressure are only meaningful after a bench test. This pump carries its own internal element, so no component inside it carries a number we can bind to 0414755018, and none is printed here.
Cross-Reference & Interchanges
Need an 0414755018 cross reference or an 0414755018 equivalent? The numbers below are the ones buyers match against. All are reference interchanges only.
Further references circulate on marketplace listings, but we print only the numbers we can corroborate across independent sources, which is why the Liebherr host number and the KHD-Deutz number appear beside the Bosch part number. Numbers that turn up on a single page, or that point at a different host manufacturer entirely, are left out rather than copied, because a wrong interchange costs a customer a stripped thread and a wasted day. The control valve, plunger and delivery element inside this pump carry no number that any independent source binds to 0414755018, so we state none at all rather than a borrowed one. Send the nameplate photo and we confirm the interchange set against your build on the same RFQ.
Key Features
What the unit pump system features mean on the bench, and why this element is built for a hard-working industrial diesel rather than a light road engine.
Camshaft-driven element
Each cylinder carries its own cam-actuated element, so pressure is made in the element rather than in one place shared by the whole engine.
Complete assembly, not a part
What you receive is the whole pump body with its plunger, spring, tappet and solenoid — a complete unit, not an internal component of one.
Solenoid spill timing
The spill valve opens at the moment the control unit chooses, so injection timing is set electronically while the cam sets the pressure.
High pressure unit pump class
Rated inside the PLD high-pressure class so delivery stays consistent under sustained load on a machine working all day.
Roller tappet face
The tappet rides directly on the cam, so its face and the bore it runs in are the two surfaces a fitter inspects before fitting.
No invented numbers
Where an internal number is not published against this revision, we say so rather than filling the gap with something plausible.
New and warranted
Supplied new with a 12-month warranty against manufacturing defects, handled against the batch number on the box.
Ready for export
Foam-lined export packing, with the documentation set travelling on every consignment.
Failure Symptoms
Common unit pump symptoms on a D934 or D936, and the checks that separate a tired element from a healthy one.
| Symptom | What it usually means |
|---|---|
| hard starting unit pump | Low cranking delivery on one element or a leaking spill seat delays the first firing, so the engine turns longer than it should. |
| diesel unit pump rough running | Uneven delivery between elements shows as a lope or a beat at idle and light load, smoothing out as the engine comes under load. |
| unit pump misfire | A failing element drops its cylinder under load while the others still carry the machine, so the fault only appears when working. |
| unit pump low fuel pressure | Internal leakage raises return flow, so the element can no longer build its class pressure inside the working range. |
| unit pump black smoke | Poor atomisation from a worn element raises exhaust opacity under load, worst when the engine is asked for torque quickly. |
| unit pump cylinder imbalance | One element drifting out of step with its neighbours changes exhaust temperature spread and raises fuel burn across the whole engine. |
| unit pump diagnostic trouble code | A cylinder-balance or circuit code points at one element for a bench check, which is the cheapest next step. |
| unit pump return flow test | A return-flow reading against the PLD class separates a tired element from a healthy one without stripping the pump. |
| unit pump symptoms | A weak or seeping element drops combustion quality on one cylinder and shows up first as uneven exhaust temperature. |
Two measurements do most of the work: a return-flow reading against the class, and a bench leak check at the spill seat. Recognising these signs early keeps a pump out of a roadside failure, and on an excavator or a loader the window between a rough idle and a machine that will not start is often a single shift. The root cause is rarely the pump alone — contamination past the filter, a worn tappet face and long service hours all repeat the same damage, so fix the cause as well as the assembly.
How to replace unit pump on a D934 or D936
A bench-side walk-through of fitting for the 0414755018, from a unit pump replacement on a single cylinder to a full bench test.
Confirm the code
Match the part number 0414755018, the nameplate form 0 414 755 018 and the engine plate before a spanner moves. A single exchange on the wrong revision wastes the whole job.
Isolate the fuel and the battery
Shut off the fuel supply, relieve pressure in the supply line and isolate the battery before opening the high-pressure connections.
unit pump removal
Unbolt the old assembly, note the flange orientation, and check the tappet bore and the mounting face for scoring or debris before the new unit goes in.
unit pump installation torque
Seat the new assembly to the torque figure given in the engine manual, with a fresh sealing washer and a clean, dry flange face.
unit pump timing
Roll the engine to the timing mark before the element is clamped home. The setting is fixed by the cam position, so being one tooth out will show as a rough cylinder.
Check the unit pump mounting flange
Confirm the bolt pattern, the spigot fit and the connector keyway against the old body before you commit to the change.
unit pump priming
Bleed the supply line and crank without firing until the element is fully bled, then check for weeping at every joint.
how to replace unit pump across a full set
For a complete set, repeat the sequence one cylinder at a time. Working element by element keeps the crank position known throughout and lets you stop if one bore looks worse than the rest.
unit pump cylinder balance
After the first start, run a balance check on the exhaust temperatures and trim as the control unit allows before the machine goes back to work.
Fit a fresh sealing washer every time, work to the torque figure, and prime before the first start. The seal and the timing position are the two steps workshops most often rush. A single-element change uses the same procedure as a full set — change the worn element, not every cylinder on the engine. If the machine is going straight back onto a site, run it under load for a short period and re-check the joints before it leaves the yard.

Buyer Feedback
Field notes from workshops and fleets running the 0414755018 on D934 and D936 power.
Matched the cover number on our old pumps and the flange lined up first time. Even exhaust temperatures after a balance check. A compatible part, not an original unit — exactly what we needed at the price.
One element replaced a tired pump on an excavator; the hard start cleared and the black smoke under load dropped away. Fast quote turnaround and the box arrived intact.
