Jason,
When the rubber deteriorates on the pulley, the two pieces can and do turn
on each other throwing off the timing marks. This has happened to my 72 and
probably lots of other MG owners have the same problem. Moss lists the
pulley as NA with their number being 433-695. I believe the rubber is there
as a dampener, thus the harmonic dampener designation for the crankshaft
pulley. If the pulley turns on itself too much you could have a real
problem. If you find a solution or source for replacement pulleys please
pass it on.

Subject: Crank Shaft Pulley, Clutch plumbing, Engine Paint
Hi List: I am currently in the midst of a full restoration to my chrome
bumper 74. As I am sealing up my freshly painted engine, I have a few
questions:
Pulley
I noticed on the inside of my crankshaft pulley there is a badly
deteriorated rubber ring. The rubber ring is not on the pulley hub, it is
on the back side of the pulley - about midway between the hub and the outer
edge - it almost appears that it is glued on. Any idea on the purpose and
how I might renew it?
Clutch fluid
I intend to switch my braking system over to silicone. My decision is based
primarily on the inability of the fluid to damage my new paint job. Now,
can I use this same fluid in the clutch system? I think I can, but every
reference to DOT5 I have read deals with the braking system.
Paint
Also, I used black engine paint (from Moss). After reading the can and
asking folks at my local auto parts store, I decided against using a primer
on the block. Well, last night I was browsing the Moss catalog and I
noticed it recommended using a primer for its line of paints (but I am not
sure if it applied to the engine block paint). What is the general practice
out there? Should I sand it down again and redo, this time with a primer?
Thanks guys & gals
