Subject: [Healeys] Clutch bearing

About to replace the clutch in my daily driver BJ7. The clutch has lasted nearly 20 years but I am on my third throw out bearing/bush. In the past I have heated the bush and soaked in oil for 24hrs before installing. 
 Do you guys think this makes any difference to bush life or have any other suggestions. I do a fair bit of driving in stop start traffic so the bush gets a lot of work.
Cheers
Piet

Pieter, I'm not sure that you are using the correct part names.
The throw out bearing is normally made of carbon, is mounted on the clutch
fork and operated by the clutch slave cylinder. It requires no lubrication.
I suspect that you may be referring to the pilot bush, which is an oil
impregnated bronze bush which is installed in the rear end of the
crankshaft and, within which, the forward end of the gearbox first motion
shaft rotates when the clutch is disengaged.
If it is the pilot bush which is failing prematurely the most likely cause
is misalignment between the engine and the gearbox.
Originally 2 special pilot bolts were installed to ensure that these
components were correctly aligned.
