Title: A65T Restoration - Fork Legs - Advice Needed!
Post by: mikescott on 30 Jun, 2026, 15:00
Hello all - I'm restoring a 1970 A65T and am having difficulty with the fork legs. I need to replace the oil seals and have got two problems: 1. I can't see how to get the legs off,even with the workshop manual - do I need one or more special tools or is it possible without? 2. One of the chrome oil seal covers is free, but the other one is absolutely solid and won't move even with a strap wrench.

Any advice gratefully received!

Cheers, Mike

The chrome oil seal holders require a pin wrench. Note the two blind holes near the bottom. The factory tool is like a C wrench and has a fixed pin on the end with a screw pin on the other.
If you have a welder, you can make one. Best to use half a piece of thick walled pipe with the inside diameter the same as the outside diameter of the chrome holder. Drill a hole through near one edge and weld a pin then weld a handle across the outside. Using a piece of flat instead makes it hard to keep the wrench from trying to turn sideways as you pull.

But if you're renewing the oil seal holders a hammer and punch usually works well.

the best way to remove the seized oil seal holder without damage is old school. place the tool [ 2 tools for outside notches or inside notches] in a good vice then with a bar in the slider spindle hole, push or locate the fork onto the tool and turn the bar.

Thanks for replies, folks! I've now got one of the oil seal holders off successfully, but the old seal is absolutely solid and won't budge whatever I try.

Have you heated it yet?  I find some things get stuck sold with hardened grease, it becomes like cement.  Heat then penetrating oil on the joint, the sudden cooling pulls it in.

No, I haven't tried that yet, but will have a go!
