ATHENA Fork Oil Seal Kit 36x48x10.5 mm for KAWASAKI, YAMAHA, HONDA and SUZUKI 1974-1999

The ATHENA 36x48x10.5 mm P40FORK455036 fork oil seal kit is designed for YAMAHA DT 250, IT 175, IT 250, IT 400, IT 425, TT 500, TY 350, XT 250, XT 500, YZ 100, YZ 125, KAWASAKI KDX 125, KDX 175, KDX 250, KL 250, KLR 250, KLX 250, KX 125, KX 250, SUZUKI DR 370, DR 400, RM 250 and HONDA XR 200 from 1974 to 1999. Fitted at the top of the fork leg, under the dust seal, the oil seal keeps the fork sealed. A leak lowers the oil level, the damping changes and oil can run onto the brake disc.

Specifications

• Manufacturer part number: P40FORK455036
• EAN code: 8055681307803

When to replace it?

• Film of oil on the inner tube after a few fork strokes.
• Oil traces on the fork leg, the caliper or the brake disc.
• Fork that becomes softer on one side.

Before replacing a leaking seal, clean under its lip: a trapped grain of sand is sometimes enough to cause the leak. If it still leaks, replace the seals on both legs. Measure your seal (inside diameter, outside diameter and height) or check the original part number: the size is in the name.

Fitting tips

1. Drain and disassemble the fork leg following the manual, then remove the dust seal, the circlip and the old seal.
2. Check the fork bushings and the condition of the inner tube: a scratch or a rust spot will cut a new seal.
3. Protect the end of the tube (plastic bag), oil the lip and drive the seal in straight with a seal driver of the right diameter.
4. Refit the circlip and a new dust seal, then reset the fork oil level.

Frequently asked questions

Do I have to change both seals?
Yes: they have the same age and the same mileage. Replace both oil seals and, ideally, both dust seals.

Why is my new seal leaking?
Most often because of a scratched or pitted tube, a lip turned back during installation, or worn bushings that let the tube develop play.
