About 5501801015 - Pressure Relief Valve
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5501801015 is a pressure relief valve catalogued for MTU 396 engines. The catalog unit weight is 0.316 kg, which we use to estimate freight before quoting.
Technical Notes: Fuel system
The fuel system meters and delivers fuel at the pressure and timing the combustion process needs. Small wear in injectors, pumps, or valves shows up as higher fuel consumption, smoke, uneven cylinder temperatures, or rough running long before a complete failure.
Series 396 engines use conventional pump-and-nozzle injection rather than common rail. Injection pump and nozzle-holder references vary between ratings and older engines may carry superseded numbers.
When This Type of Part Is Usually Replaced
- exhaust temperatures differ noticeably between cylinders
- black smoke, hard starting, or knocking points to injection problems
- fuel leaks appear at high-pressure lines, unions, or pump seals
Checks Before Ordering
- Check the maintenance documentation on reusing high-pressure lines; deformed sealing cones on refitted lines are a common leak source
- Injectors should be ordered with the correct seals and copper rings for the cylinder head
- Exchange (EX-prefixed) injectors and pumps are a practical option when new units have long lead times
