B25/B44 Fork Oil Seal Holder removal tips

Postby gunnag » Sat Apr 11, 2009 4:37 pm

Im rebuilding a pair of B25/B44 forks and would like to remove the chrome oil seal holders.

In the absence of the correct tool, I wondered if anyone had some tips on how to unscrew the oil seal holders from the fork bottoms.

Im trying to avoid scratching the oil seal holders so dont want to use pipe grips or similar.

Have already tried a rubber strap wrench but as the chrome finish is so smooth I cant get any purchase.

All info welcome !

Gunnag,
I use a strap wrench like you suggest but wrap a strip of rubber cut from an inner tube around the seal holder before using the strap wrench. This has always worked for me.

Hi Ed,

thats a great tip, I tried using an old inner tube as you suggested and the strap wrench grips real good but I still cant get the oil seal holders off. Looks like they are seized tight so Im going to soak them with wd40 and maybe try with a bigger strap wrench :roll:

Hi Gunnag,
Just be careful not to get too high up on the seal holder or it will want to cave in on you ok?

get a bit of 3/4" ply about 4" square ,bore a hole using either a hole saw of the appropriate dia, or mount the ply in the lathe and bore to the correct dia.once this is done put 2 hack saw blades in the frame and cut into the bore from one side of the square.(the 2 blades give a wider cut). once this is done slip the ply over the seal holder in the vice and tighten. this will now allow you to turn the fork leg without marking the chrome. to make a more permanent tool use a bit of tufnol.

I made my own tool to get the seal hoders off. A piece of tube with 2 "lugs" on the bottom to match with the slots in the shouder on the inside of the seal holder. I would have to measure it but I think it was 1 1/4" N.B. schedule 40 pipe (blue band).

PM me your email address and I will send you some pics.

It might be just me but isn't it easier to use the right tool? It's readily available and got to be worth having unless you are never going to own another BSA ever again!

It is a bit messy but I have found that using the correct tool ( as shown in the previous post) I have had more luck mounting the tool in the vise and turning the leg. I seem to be able to get more down force this way which stops the tool riding up and chewing off the lugs.
However we now have a press so I will be experimenting mounting them in the press as I have killed about 3 or 4 leg tools to date.
