Oil Seal 25mm

The 25x35x7 oil seal is used in pressure washer drive assemblies, where maintaining tightness in the oil zone while working with a shaft or axle is required. In service practice, it is used for repairing oil leaks, gearbox rebuilding, and overhauls of the machine’s mechanical components.

MPN / reference: 41024
Size: 25x35x7
Version: replacement part

APPLICATION

The oil seal is used in typical service work:

• sealing a shaft or axle in the oil section of the assembly,
• repairing oil leaks in the drive system,
• rebuilding the gearbox and mechanical parts of the pressure washer,
• inspections of machines used intensively in workshop and service conditions.

SYMPTOMS - WHEN IT IS WORTH REPLACING

It is worth considering replacement of the oil seal when the following appear:

• oil leaks around the shaft, axle, or drive housing,
• signs of oil seepage in the seal area,
• reduced tightness after prolonged operation under load,
• hardening, cracks, or deformation of the sealing lip after disassembly,
• signs of wear on the surface cooperating with the seal.

HOW TO CHOOSE THE RIGHT COMPONENT

Selection of the oil seal should be done carefully:

• verify the 25x35x7 size,
• confirm the manufacturer number: MPN 41024,
• compare with the removed part: inner diameter, outer diameter, height, and working profile,
• check the condition of the shaft and the seat, because worn surfaces may shorten the service life of the new seal.

With oil seals, even a slight difference in size or profile can cause leakage.

COMPATIBILITY

The oil seal should be selected based on MPN 41024 and the 25x35x7 size, according to the parts list for the specific assembly. As a replacement part, it should only be used where the size, profile, and intended use match the given drive system.

What does it mean that this is a “replacement part”?|It means a substitute part selected for a specific dimensional and functional application.

Will a replacement part work the same as the original part?|It can work correctly if it is properly selected for the specific assembly. Our replacement parts are checked and tested in service conditions.

Can the oil seal be selected only by the 25x35x7 size?|That is the starting point, but it is not always enough. It is worth confirming the seal profile, the way it works in the assembly, and compatibility by MPN 41024 or the removed part.

Why does a new oil seal sometimes still let oil pass through?|Most often the cause is not the new part itself, but a worn shaft, damaged seat, incorrect installation, or contamination on the sealing surfaces.

When replacing the oil seal, is it worth checking other drive components as well?|Yes. In service practice, it is worth checking the condition of the shaft, seat, housing, and the oil level and condition, because these elements directly affect the durability of the new seal.
