5550100051 Specification
About 5550100051 - Nozzle Holder with Nozzle
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
5550100051 is a nozzle holder with nozzle catalogued for the MTU 12V 396 TC14. The catalog unit weight is 0.657 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 Injection pump and nozzle-holder references vary between ratings and older engines may carry superseded numbers.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

Engine-series references do not confirm every installation. Final fitment of 5550100051 depends on the full engine serial number and assembly position.
Common Replacement Scenarios
This part is commonly replaced when:
- combustion quality, fuel delivery, compression, or exhaust temperature is outside normal range
- installation position and matched mating parts must be checked before replacement
- overhaul buyers need verified valve, nozzle, injector, or pump references before dispatch
Usually Ordered with Nozzle Holder with Nozzle
Injectors are refitted with new sealing rings, and the high-pressure connection is checked at the same time. These MTU 396 references are commonly checked in the same job; each still needs its own fitment check.
