MGB Rear engine plate

[WillR]

The torque for the bolts holding the plate is hiding from me in the bently manual. Are these picky?
Thanks for looking.

Not really. But the book has the 5/16" @ 20lb/ft and the 3/8" @ 30lb/ft.

Just be sure to replace the lock-tabs.

HTH!

Thanks Doc!

First thing I'm trying to put together and realized I only THOUGHT I took to many pictures.
I'm seeing some have the rear main seal retainer. Seems like one of three things is possible
1 I misplaced mine
2 some one else has been in this engine before me AND lost it ( not to likely)
3 only earlier models had one.

The large bolts are 9/16 and have lock washers no tabs I remember or came in my nwip set.
The bently manual is surprisingly un helpful when it comes to the rear plate. Probably because it should be a cake walk
And I'm complicating it

I realized I did not ask a clear question.
Should my rear main seal have a retainer that I have misplaced?

The top two bolts had lockwashers. the rest had tabs.

I don't recall whether the later (later than 1969) engines had the retainer or not.

A poor photo but if you save it to your machine and zoom in, you can see the bolts and tabs.

All 5 mains had the seal retainer and later 5 mains did not have lock tabs. Very shallow head bolts and locks. The longer 3/8 bolts with the thicker heads are at the top of the backplate.

well I figured out why I didnt remember this plate at all. I left it on for the machinist. Found it in the box of old bearings and valves. I also found this guy. I know its not mine...

Thank you for the responses and help.

MGB distributor drive and retainer in bottom pic is a good thing to have as extras if they are not from your engine!
