Thread: 3 Bearing Oil Seal

The two half moon bits you refer to are the piece that hold the rear main seal. Make sure you use a good gasket sealant (without a doubt Hylomar Blue is the best for this) on the rubber faces of them and also where the two halves join together.
From memory I think the correct method of assembly is to put the seal over the crank and then insert the spring and join it up. Then bolt the top half of the rubber coated retainer in place (over the seal). Bolt the bottom half of the seal retainer to the seal block, make sure the "T" seals are in place, then bolt it up into place. A couple of guides are best for ensuring the "T" seals don't get damaged along the way. I think it's recommended the cork compound "T" seals are best if soaked in oil overnight, before installation.
It's a bugger of a job to have to do again, so best do it right the first time.


Alternatively you can bolt the block in place, then fit the rear main seal, then install the two piece seal retainer. I did this recently to fix a leaking rear main (not "T" seals) as an in vehicle repair, and it was successful.
Good Luck!!!!

In picture two of yours, the seal fits in the cavity/groove between the silver block and the rubber half moon piece (as you call it).
With luck someone else who is smarter than me with computers, will be able to put a pointer on your picture to identify the spot.


Cheers, Mick.

When sliding the cap back in, use some feeler gauges between the block and the cap to allow the T gaskets to slide over without cutting.
