Hi I am bolting the silver bell housing ring to the block, having replaced the rear oil seal. What is a good torque for the 8 bolts. Also when I attach the bell housing to this ring what would be a good torque setting for those bolts ? It is a 64 3litre with auto trans.

I think you mean the bolts which secure the bellhousing to the engine? If so, as far as I can remember (though it was long time ago!) back in the day we used to tighten these bolts to 30lb ft. Others will no doubt be able to report on the official figure if different.

Hi p5Andrew, thanks for your help, I thought about 30 lbs ft was a good torque. I have had a good look at the manuals etc but find no reference to how tight they should be. I also wondered what a good torque setting would be for the bell housing to the ring attached to the engine. They are studs and I did not want to strip them from the aluminium. I was going tighten them by hand but I did not want the bell housing falling off. When I removed the nuts they were not very tight.

Torque settings of that period were only just becoming prevalent in the 50s and only then for critical or safety related items especially with the relatively new alloy castings (from the 1930s with Rover and others). Time served mechanics tightened fastenings by feel using the correct spanner size and length.
Sadly, this skill has been almost lost on the younger generation of mechanics who have far more specialised equipment at their disposal to give the deemed but not necessarily correct outcome determined by theoretical data.
