Shockmaster fork help

[ozzie]

I have a prewar shockmaster fork and would like to know if it is normal to have side to side movement at the top pivots. There doesn’t seem to be any wear in that area causing the problem. It seems to me shimming washers are required on the pivot bolts to make it tight.

Thanks for your help.

It should not have play in it. Here is a pic of mine and it has a spacer on the inside. V/r Shawn

Thanks for the prompt reply Shawn. Is the spacer factory fitted or did you add it?

I restored this bike about seven years ago so I don’t recall. I do know without them you are going to have some slop. V/r Shawn

Not sure if slop or movement would be the result of the shoulder area of the shoulder bolt fitting too loosely in the pivoting forks?

If tightening is the solution, then perhaps the spacer washers should fit the wide shoulder, rather than the narrower threaded area?

I used metal washers and the fork legs are snug now but I am going to try some hard nylon washers next week.

I was going to suggest delrin/nylon type bushing washers.
Not OG, per say, but they may make the pivot performance better.

I agree. I’m not concerned with originality as the fork will be going on a rat bike I’m building. I had the fork left over from my 39 Supreme.
