007603016105 Specification
About 007603016105 - Copper Sealing Ring
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
007603016105 is a copper sealing ring from the coolant pump group of MTU 956 and MTU 1163 engines. It is the later number for 0009976644, 06.56190-0708, 06561900708, so lists quoting those numbers are normally supplied as 007603016105. The catalog unit weight is 0.003 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- Superseded gasket numbers often reflect a material or thickness change, so mixed old and new gaskets on one joint should be avoided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
