X52808100004 Documented Identification
- Fuel-system function
- The MTU parts catalog places X52808100004 in the low-pressure fuel-pump group, not the high-pressure injection-pump group. Reference
- Documented installation
- 20V4000G83, example engine serial 528100707; BOM X00040005, drawing 08100172d, item 50. This is one documented engine build, not universal 4000-series fitment. Reference
- Separate drawing items
- The link X52408100002 (item 150) and O-ring 700429083000 (item 250) have separate catalog numbers. They are not automatically included with a pump quotation. Reference
- Mounting hardware
- Retainer X52607700008 and screw 000933010116 are separately listed in this drawing. Specify a bare pump or itemized assembly in the RFQ. Reference

About X52808100004 - Fuel Delivery Pump
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
X52808100004 is documented in the low-pressure fuel-pump group for the example 20V4000G83 engine build. Distinguish the pump from the coupling link, O-ring, retainer and mounting screws shown as separate drawing items. A complete pump assembly must have its included items stated in the quotation.
Technical Data Status
Published catalog details help identify this part, but they are not a controlled drawing for the item offered. Measurements that are not shown here still need confirmation before substitution or order.
- Check the full pump identification plate, drive interface, flange, inlet/outlet arrangement and offered condition.
- Flow and pressure ratings, installation dimensions and test documentation are not provided by the cited parts drawing. Request an offered-unit specification.
- X52808100015 is a later imported-catalog reference; verify whether the later pump needs related connection or mounting changes.

Ordering Notes
Do not describe X52808100004 as a high-pressure injection pump. Request link X52408100002 and O-ring 700429083000 separately if required for the documented installation; the drawing does not define shipment contents.
X52808100004 FAQ
Is X52808100004 a high-pressure injection pump?
No. The cited MTU example catalog places it in the low-pressure fuel-pump group. Identify the high-pressure pump separately if that is the required component.
Does X52808100004 include the link and O-ring?
The parts drawing gives those separate numbers and positions. Ask for an itemized quote specifying whether the link, seal, retainer and hardware are included.
Is X52808100015 a confirmed direct replacement?
It is a later reference in the imported catalog history. Direct fitment and any related modifications must be checked against the engine serial number; the cited older OEM drawing does not approve the successor.
What replaces X52808100004?
Catalog history lists X52808100015 as the later number. We check whether X52808100015 can be fitted on its own or needs related parts changed, and quote X52808100004 where it is still available and preferred.
Verification Notes
- Catalog references and engine-series listings require confirmation against the full engine serial number before order.
