[Healeys] 100 rocker shaft question

[Alan Seigrist]

All -

Okay I got alot of great feedback, thank you.  Took the rocker off and the
pedestals slide around.   Was a bit confused at first because this is for
my A90, and I have a spare a90 rocker from 1949 which is different, and on
that one the rocker pedestals are an interference fit (the rocker arms and
pushrods on an early A90 are really cool, but complicated... they eliminate
tappet noise but are too fiddly and complicated).

But my A90 actually has a later motor which is the same as a 100, and I
have a rebuilt rocker on it from rockerarms.com.

It seems the two inner pedestals are free floating, and the two outer
pedestals have a slight interference - I think the interference fit is to
hold the shaft in placeso that the banjo bolt will go in the hole on the
shaft.  I can remove the outer pedestals off with a slight tapping with a
rubber mallot.

Anyway, hope that helps.

Cheers,

Alan
