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
|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
|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?
