The push pin does wear out in time. I know this because I had this problem
about ten years ago. Back in those days, living in rural Wyoming, I could
not buy the fork separately so I replaced the entire clutch master
The fork bushings or the pressure plate seem like possiblities (Graham
Mccann's suggestion; the release bearing is one year old, the clutch disc
was replaced ten years ago, and the pressure plate was old even then). But
that means removal - perhaps the height of excitement in MG mechanics.
In a related note, an old MG mechanic showed me an unusual trick some ten
years ago. By drilling a hole in the transmission bell housing of a
diameter of over an inch (25 cm), one can access the pressure plate bolts,
undo them, and pull the transmission out without removing the engine. Or in
my case, separate the engine and transmission to get to the clutch.
However with my OD transmission, I found it such a tight fit that its just
as easy to pull the engine forward enough to remove the transmission.
Looks like a fun weekend ahead.
