So I’ve taken apart my C3035 Newton Bennett shock absorbers.
These are used on early XK120 and all Mark V but not Mark VII.
There is a fine threaded retaining ring inside the outer sleeve that
unscrews after you remove a little split pin.
Then when I got the sleeve off I found the slimy gooey remains of what felt
like a mushroom but looks like it might have once been a rubber ring.
The top end also unscrews and I found a couple of o-rings in there but I
decided to stop and ask the collective wisdom of this group.
The question is, O wise guys, does anybody know what this bit of rubber
looked like when it was new. Was it just a bump stop ring that bumped
against the retaining ring when it was extended, or was it a bellows to keep
the dirt out?
And does anybody sell new rubber bits for these things?
Here are some pictures.
I did some googling and found pretty much nothing on this Newton company
except they also made clutches.
The damping function seems to be fine, just leaks a bit at the top, needs
new o-rings and maybe a little more hydraulic oil.
Incidentally the cross section picture in the manual is the wrong model
shock, doesn’t show this rubber mystery ring.
