Hi,
I know what's wrong with the damping on my R12 but don't want to go in too heavy handed trying to fix it without asking your advice.

The chrome leather damping washers (2061620460) are worn and need replacing. But howto do it? Does the valve piston (2061620510) unscrew? In the parts book it looks like it doesn't come aprt but I can't see how else the damper washer can be replaced.

Someone out there will know - do I start using heat and brute force to try to unscrew the thing or is there another way?

Thanks,
Geoff

You don't need to unscrew the

You don't need to unscrew the valve body to remove and replace the leather seal. The seal is held by the top in a slot machined into the body. If you have a seal there now, you should be able to pull the bottom of it, which should be free, and remove it from the slot. Then you can pull it down and off the body.

When the forks compress, the oil is pushed up to the leather seal, which blossoms out against the fork tube and forces the oil to push against the valve (206 162 053 0) inside the valve body, which is normally held closed by the spring. The pressure pushes the valve up and allows some oil to pass through the body. When the fork stops compressing, the valve closes, and when the fork expands again, oil dribbles past, between the seal and the fork tube, back to the bottom.
