Fork Seal Removal
« on: September 20, 2023, 09:35:51 AM »
I'm stripping down my forks to get the stanchions re-chromed.  I'm struggling to remove the old fork seals, as I want to replace these when rebuilding the forks.  The Haynes manual, and some YouTube videos, advise that the seals are "simply pryed" out - I've tried this without success.  Are there any hints/"tricks of the trade" to remove these?  TIA

Have you tried using one or two long thin woodscrews - screw them into the middle of seal sides then use a tool to pull them out with the screw. I'm assuming you have removed the top circlips. Use a  piece of wood to protect the fork top if you are levering against the alloy top of the leg.

Mine were a pig to get out.
I resorted to lots of heat and then leverage, with protection for the top of the slider as Ted says.
Good luck

Hi,

This tool available on Ebay
Sealey Rubber Seal Gasket O-Ring Puller Remover removal Tool - AK7000

did a super job for me on the forks and would be versatile enough for other jobs. ;)

Hope this helps.

Got the same type except mine Snap-On. Works well but as Bryan says be careful you don't gouge the alloy wall. I use a thin sheet of metal to protect the top of the fork.

A bit of heat works wonders too

Thanks all - much appreciated

Circlips are removed - I learnt that the hard way many years ago!

With regard to the use of heat - do you concentrate the heat onto the leg (to expand the metal), or the seal (to soften it)?

I've never needed heat but it would soften or melt the rubber part of the seal so it might be safer heating the seal than risking melting the alloy. I suspect a hair dryer on the seal would work.

Heat the alloy, don't use a naked flame or you risk blistering the lacquer, hot air gun will do. As the alloy expands it will allow the seal to pull out easier.

Success!!

Heat (from hot air gun) onto metal did the trick, and I was able to pry out the seals.

Thanks for all help - much appreciated.
