Hmmm. Well, from Paul's description of the oil pump cover, I definitely
have at least the wrong oil pump cover brazed onto the back plate. However,
the clutch was working fine until the plate exploded so I don't have the
problem Stewart outlines. Ergo - Perhaps I have the correct backing plate
with the wrong oil pump cover brazed onto it. Iis this possible??
The pilot bushing looks as if the shoulder on the transmission input shaft
has been up against it, but it also looks as though it is not all the way
into the flywheel which could also explain the input shaft chewing on it.
Sooooo..... What is the proper thickness of the backing plate on the 1275
engine, and where do I get the proper one and the proper oil pump cover and
gaskets if I have the too thin plate for the smaller displacement engine??
Brad may have been right about the Shipwrights Disease, but for different
reasons entirely!
Cheers!!
