ATHENA Fork Oil Seal Kit 33x45x11 mm for YAMAHA TW 200, YZ 80 and KAWASAKI KX 80 1983-2015

The ATHENA 33x45x11 mm P40FORK455024 fork oil seal kit is designed for YAMAHA TW 200, YZ 80 and KAWASAKI KX 80 from 1983 to 2015. The fork oil seal keeps the oil inside the fork leg while letting the inner tube slide. It is a wear item: dust, mud and impacts on the tubes eventually damage its lip, and the fork leaks.

Specifications

• Brand: ATHENA
• Manufacturer part number: P40FORK455024
• EAN code: 8055681307773

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.
