The spring/damper assembly needs attention. It leaks and looks generally distressed.
I see new replacements are not given away, so will likely get this one fixed.
There is a ball joint assembly top and bottom (Heim joint I'm told), that is a press fit in the damper ends.
The top one had moved over, to the extent that the damper was rubbing against the frame.
It looks, from the sketch in the parts book, that there should be distance pieces on either side of the Heim joints, all missing on the bike here.
Would I be correct in assuming that they are steel spacers, with two different outside diameters?
It looks like something like that would work, to help retain the joints in their proper central positions.

Don't be trying to work all this out yourself, find a local suspension specialist and drop it in for service. Motorcycle suspension is difficult to work on without the right tooling.

Hi Jorian,

I agree with JWilliam. If you don't have proper tools (and the expertise!) for such an overhaul then leave it to a specialist. I've had my rear shock fully overhauled, see viewtopic.php?f=3&t=7937 for more details. Good luck!

Huh , what a couple of soft cocks

Jorian ,you don't say what type of shock you have . Mine is a mazocchi duo shock. The only special tool needed is a spring compressor. There used to be kits available to rebuild the mazocchi and I'm sure Olin's did one ( there have been 2 stock shocks used Mazocchi and Olin's ). The rebuild ain't much more than cleaning ,replacing parts in the kit , and re-oiling/reassembly. The missing distance pieces don't need someone with a degree to replace either. Even shoving a few washers in there would do the job .......admittedly some nice spacers would look better than a bunch of washers but they would work . Apart from us lot eBay and Google are your friends too

This one is a Marzocchi DuoShock too.
It was sent to a rebuilder with a good reputation, decision being the owner's.
They couldn't advise about the spacers, but I think I can see what's needed and will fire up the trusty lathe and make some.
Always good to get others' thoughts, so thanks fellas.
