5321800143 Specification
About 5321800143 - Oil Spray Nozzle
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5321800143 is an oil spray nozzle catalogued for MTU 2000 engines. The catalog unit weight is 0.030 kg, which we use to estimate freight before quoting.
Technical Notes: Lubrication
The lubrication system supplies oil to bearings, pistons, the valve train, and turbochargers, and on many engines also cools the pistons. Low oil pressure is one of the main protective shutdown triggers, so pumps, valves, and coolers in this circuit are critical to availability.
When This Type of Part Is Usually Replaced
- oil pressure drops at operating temperature compared with earlier readings
- oil analysis shows coolant, fuel dilution, or rising wear metals
- the oil cooler leaks internally or externally
Checks Before Ordering
- Use an oil of the category permitted for the engine and fuel in use
- Pressure-relief and regulating valves should be replaced with their springs and seals
- After a bearing failure, clean or replace the oil cooler to remove debris

Engine-series references do not confirm every installation. Final fitment of 5321800143 depends on the full engine serial number and assembly position.
Usually Ordered with Oil Spray Nozzle
Injectors are refitted with new sealing rings, and the high-pressure connection is checked at the same time. These MTU 2000 references are commonly checked in the same job; each still needs its own fitment check.
Cross-Reference and Superseded Part Numbers
5321800143 has no public alternative number listed in our current data. We still check old-part photos, engine serial number, and catalog position for supersession before quotation.
