Title: WD B40 Fork Seal Holders
Post by: DWS on 26 February, 2017, 18:06:40
Hi

Trying to remove the chrome fork seal holders using a new correct special tool but they will not shift.  Am I looking at applying some heat to them and/or longer bars on the arms of the tool.  Not done this before so any advice please.

They can be very difficult to move - you have to be careful applying too much force with the special tool as it can ruin the slotted ring inside the seal holders, making them even harder to unscrew. It's best to apply heat as long as you are going to re-paint the fork sliders afterwards.

Hi Arthur

Thanks for that, yes the sliders are going to be painted so I'll try the heat treatment next...

Normally you just need to break the stiction after which they should unscrew easily. It's sometimes best to put your weight down on to the tool to stop it jumping out of the slotted ring and damaging the slots - a bit like trying to undo a stubborn slotted screw.

Noted.

I don't reckon the forks have been apart since the bike left the factory in 1970, as its only got 997 miles (documented genuine  :) ) on the clock.  But that's another story...
