About 5841800143 - Oil Spray Nozzle
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5841800143 is an oil spray nozzle catalogued for MTU 956 and MTU 1163 engines. The catalog unit weight is 0.248 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
