I recently noticed a small leak on one of the FJ's forks. The bike's MOT (annual safety check) was due so I decided to replace the seal. This is fairly simple job and one I've done in the past. A couple of special tools are needed though. From my records I see that the seal was last replaced 8 years and 55,000 miles ago so not bad.
The leak is very slight but I guess it won't get better |
Tip - loosen the fork top bolt before removing the fork otherwise it's tricky to get off |
Fork removed |
Drain oil |
This is the dust seal |
The metal inside the seal has corroded and burst the seal. I don't think this caused the leak but it's not good because flakes of rust could score the fork leg. |
I got a pair of oil seal & a pair of dust seals |
To strip the forks a special tool is needed. It's a long bar with a 27mm hex head. I made this one years ago. |
It goes down the fork to allow the damper screw to be removed |
The fork then comes apart |
There is some pitting on the fork leg |
The pits are outwith the stroke of the seal (otherwise the tube would be scrap) I buff them smooth to avoid damaging the new seal when fitting. |
New seal installed |
To push the seal into place I made this tool a long time ago |
New oil |
The dust seal on the other fork was a bit crusty so I replaced it as well |
All done. The fork protectors are after market. I don't know if they do any good but why not? |
