8492000005 Specification
About 8492000005 - Rotary Seal
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
8492000005 is a rotary seal catalogued for MTU 956 and MTU 1163 engines. Catalog history lists X58420200036 as its later number; we check whether the later part can be fitted alone or needs related parts changed with it. The catalog unit weight is 0.145 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- Superseded gasket numbers often reflect a material or thickness change, so mixed old and new gaskets on one joint should be avoided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
