To pin or not to pin

[peejay4A]

The newly skimmed flywheel and new ring gear are now installed. Clutch plate and cover next. Should I roll pin the release fork to the clutch cross shaft? I'll be using a hardened taper pin and lockwire.

6mm high tensil bolt it.

I just used a new pin and lockwire, ST didnt pin it.

 

If the pin was changed when the clutch needed attention perhaphs the known problems wouldnt arise.

That depends on the quality of the pin and if you lapped it in

When I restored my TR6 I did not lap the pin in, it proved a big mistake and after 3000 miles the gearbox was back out to replace the pin!!

This time I brought a good quality pin from TR enterprises and lapped it in, new lock wire then I drilled and reamed a 4mm hole through the fork and cross shaft and inserted a roll pin

No issues since 7000miles on.

So to answer your question in my opinion add the roll pin

Cheers Phil

Weld it to the shaft...unless you enjoy replacing pins

Tricky replacing the cross shaft bearings if you've welded it though

 

So how easy is it to knock in and remove a roll pin when the assembly is in the bell housing? I'm leaning towards an H/T nut and bolt through the fork/shaft as there's a nicely ground flat part on the fork.

Carpe diem.

 

Taper pin lapped and fettled so that it tightens fully. Then a 5.6mm roll pin through the cast boss on the release fork. Now if I can find out how to install the double shaft bearings I might be able to join gearbox to engine.
