I had a close call where the factory cam-to-chain wheel set screws had
stretched and only the lock tabs (and the timing of my routine inspection)
saved the day. I talked to the Triumph parts manager, and he sold some up
rated set screws to me. They had the same part# but you can ID them easily as
the top of the heads are rough looking. I stopped reusing old one factory
ones!

fot, at a recent race at sebring the old tr 3 went "bang" and stopped
running. external signs were that the engine turned over like there was no
compression, the dist. didn't turn and the push rods weren't going
up/down.
inside the cam sprocket bolts were sheared and the chain cover center bolt
was
sheared. the crank turns freely, the cam turns freely and the valves go
up/down with no extra effort. the bolts were the stock shoulder bolts,
the
locking tab was in place with the ears bent up in lock position.any
ideas/suggestions as to why the bolts broke? thanks, ken m. tr 3 vintage
racer
