About X54514100028 - Diaphragm
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
X54514100028 is a diaphragm from the bleed valve group of MTU 956 and MTU 1163 engines. The catalog unit weight is 0.016 kg, which we use to estimate freight before quoting.
Technical Notes: Gaskets and seals
Gaskets, O-rings, and sealing rings keep oil, coolant, fuel, charge air, and exhaust gas in their own circuits. On high-speed MTU engines they work against high combustion pressures and frequent thermal cycling, so a seal that looks intact can still have lost its elasticity or set to the shape of the old joint.
When This Type of Part Is Usually Replaced
- a joint has been opened for inspection or repair, even if the old seal looks usable
- oil or coolant weeping appears at a cover, pipe flange, or housing
- a coolant test shows oil contamination or combustion gas in the cooling system
Checks Before Ordering
- Material matters: fuel-system and coolant-system O-rings of the same size can use different elastomers
- Superseded gasket numbers often reflect a material or thickness change, so mixed old and new gaskets on one joint should be avoided
- Order the complete set for a joint rather than single pieces when the cover or head comes off

Engine-series references do not confirm every installation. Final fitment of X54514100028 depends on the full engine serial number and assembly position.
Cross-Reference and Superseded Part Numbers
X54514100028 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.
Other Parts in the Same Assembly Group
Catalog descriptions for MTU 956/1163 engines list these part numbers under the bleed valve. The grouping follows the catalog text; it is not a confirmed kit list or a drawing revision. Parts in the same group are often renewed together, but each reference still needs its own fitment check against the engine serial number.
| Part number | Description |
|---|---|
| X59699100286 | Pressure Spring |
| X59699100285 | Pressure Spring |
