About X51699100034 - Radial Lip Shaft Seal Aux PTO End
Published catalog details are identification references. They do not establish current stock, supplied condition, or confirmed fitment for your engine.
X51699100034 is a radial lip shaft seal aux PTO end catalogued for MTU 2000 engines. It is the later number for 0259973847, so lists quoting that number are normally supplied as X51699100034. The catalog unit weight is 0.156 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- Superseded gasket numbers often reflect a material or thickness change, so mixed old and new gaskets on one joint should be avoided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
