4421800543 Specification
About 4421800543 - Oil Nozzle
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
4421800543 is an oil nozzle catalogued for MTU 183 engines. The catalog unit weight is 0.095 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 4421800543 depends on the full engine serial number and assembly position.
Usually Ordered with Oil Nozzle
Injectors are refitted with new sealing rings, and the high-pressure connection is checked at the same time. These MTU 183 references are commonly checked in the same job; each still needs its own fitment check.
Cross-Reference and Superseded Part Numbers
Catalog history distinguishes earlier and later numbers where documented. Reference-only entries do not establish replacement direction or interchangeability. Confirm the offered number against the engine serial number and installation.
