Twins / Re: A65T Fork Slider Length

Wow - thanks for all of the information.
I checked on the weekend and my spindle caps also have the counterbore - so it seems that everything is correct. The bike is original in every other way and shows less than 10k miles so I can't imagine why one of the slider legs would have been changed.
The different leg lengths might also explain why the manual says to tighten the thicker RHS cap first. This leads to the question - why? Maybe it does have something to do with the brake forces as suggested by Charles - who knows. Unfortunately after nearly 50 years, tightening the caps (even with some preload (my wife) on the forks), does not fully align the spindle by compressing the longer LHS leg, but rather cock's the wheel off centre - the reason I first started this investigation. The only way I can get the wheel vertical is to shim the bottom of the RHS fork leg a few mm, hence my original thought of simply filing down the longer LHS leg.
I've now played around with the various seals and spacers and think that I can 'extend' the operating length of the RHS leg by placing an additional washer above and below the oil seal. I might even skim a mm off the LHS upper bush flange too. Less drastic and permanent than attacking the leg itself. I have some parts on order and will let you know how it goes.
If anyone can see an obvious flaw in my logic, please let me know.
Cheers
Andrew

Hi Bess,
here are the images. It seems both have the 'counter bores' if they are the small dimples behind the drain holes.
Rather than file a deeper axle groove in the longer leg, I might just shim the oil seal holder 1/8 inch to make the total length from spring seat to axle the same. What do you think?
Cheers

Thanks Julian,
so it seems I have different model sliders. Any idea which one is correct, or what the correct part numbers should be?
Cheers

Twins / A65T Fork Slider Length
« on: 30 October, 2017, 12:39:53 »
Hi,
I'm just returning to British bikes via a 1970 A65T (Pre-OIF) project. Previously I've restored a Bantam and B31. I'm a new member of the BSAOC.
On rebuilding the forks, I cannot correctly align the front wheel. It appears that all components on both sides are identical except for the sliders and axle/spindle caps. The RHS (Brake plate) slider seems to be ~ 1/8 inch shorter (from top of slider to top of spindle groove) than the LHS, with end caps also showing ~ 1/8 inch difference.
- Have I got sliders from different models?
- Which one is correct?
- Can I just file down the spindle groove on the LHS slider?
Any advice would be appreciated.
Cheers
Andrew
