stretch bolt

[rudi]

For the big end bearing caps the original bolts that need a tab washer are not longer availible. Hence stretch bolts are the only option left.

Do these stretch bolts need a plain washer or should they be torqued down w/o any washer at all.

I remember using stretch bolts w/o plain washer for fitting the flywheel. Later it appeared that thes bolts were protruding at the block side scraping the cranck seal housing.

Thanks for advise, Rudi

Rudi according to the Moss catalogue no washers are used with the stretch bolts and also they should never be re-used.

Correct me if I'm wrong, but I always assumed the original bolts were reusable, in which case there must be plenty lying around in scrapped engines (even in Belgium).

I was told by a well-known TR specialist that the 4-cylinder engines are usually only useful for the crankshaft (if at all) so you should be able to pick one up quite cheaply and get lots of other spares out of it.

I just re-built my engine again and I still have all the original bolts for the con-rods and for the main bearings. I have 174,000 miles on these bolts and I've had them out 5 times now. There are no flat washers or lock washers under any of them, but I used new lock tab retainers each time for the con-rod bolts.
