Whats this??
« on: June 18, 2016, 09:33:18 AM »
Hello Chums,
I was a bit peed off to spend £40 on a set of gaskets from DS only to find that some O rings are missing; like the crucial ones between the barrels and head.
However, also got some rubber oil seals and don't know what they are for; don't remember seeing these on the strip down.
They are soft rubber rings about 8mm high and 15mm in diameter and there are 8 of them.
Any ideas?
Thanks in advance.

Hi Yozzer, thanks for the reply.
Don't think I've got any of those; just got 2 big dowels (part no 11) at each front stud.
What happens if these are left out?
Didn't find any when I took it apart....
Cheers
Phil
