Title: Fork tube straightening Post by: flipper on July 06, 2013, 04,31:10 PM I picked up a drum brake front end for an '83 TT600 a little while back.
Intitally it looked to be okay, but upon disassembly, I've discovered that the chrome fork tubes have a slight bow in them. If you roll the chrome tubes on a flat surface, there is about 3mm of bend in the overall length - not a huge amount, but it is causing binding of the forks when they are compressed without the springs in place. Does anyone know of a place that can straighten these out? And what sort of cost is associated with it? Thanks Peter Title: Re: Fork tube straightening Post by: john t on July 06, 2013, 05,07:00 PM I picked up a drum brake front end for an '83 TT600 a little while back.

Thanks Peter Garage press and a block of wood should do the trick Title: Re: Fork tube straightening Post by: flipper on July 06, 2013, 06,19:37 PM Knowing my luck, I'd probably squash the tube flat!
I was under the impression that it needed to be done with v-blocks and a dial gauge to make sure it was straight.

"V" blocks and dial indicator is the ideal way of doing it but not everyone has them and probably a over kill.

He's a good AMTRA friend and has been hassled by some of my requests over the years!

Each to there own I was under the impression that it needed to be done with v-blocks and a dial gauge to make sure it was straight. As you said it is only 3mm deviation cut your self 3 vee blocks out of wood if you have a hole saw the same size as the fork tube even better drill a hole in the wood and cut it half set it up an the bench mark your high spot and give it a gentle press if it doesn't work take it to a shop nothing venture nothing gained PS only use wood near fork tube |
