Whats the proper way to put a new rear main seal in? I've already stuffed one up. Its a 1600 twin port. Is there any trick to it?

use a tool to pull em in with the gland nut.

tool is like a super oversized washer, under the nut whala!

use the instalation tool to make it sit in correct

i have always just used a rubber mallet....

with much caution obviously

I bought mine from Gene Berg bout 25 years ago, you can try Vintage 9789-1777 they may have in stock

Go Dave!

i've always just used a large flat piece of wood to tap in it evenly
never had any probs
just chamfer the case edge with a stanley to remove any burs that might stuff the new seal and put a bead of sealant around the seals outer edge
tap in gently & bobs ur aunty
make sure to get ur endfloat right before hand too

Wynns Stop leak !!

Hitting it with a flat piece of wood would get it flush with the case, but how do you push it in past this point? I can get it flush with the case easy enough. I have also been putting it in dry. Are you meant to use any sort of lube or anything?

it shouldnt be in any further its meant to be flush with the case flange other wise it wont seal on the flywheel properly

For those with access to a lathe, this is what the insertion tool looks like.

"insertion tool"......

I aways use some lubricant/gasket cement or even a fine film of silastic around the seal....
Knock it in flush with a wide thick flat piece of wood or a large socket... I usually use a large socket, but My Son had a couple of special tools made... the seal needs to go in just below flush or the flywheel can contact the seal...

also put a couple of drops of oil in between the two seal lips in the centre and run the oil around the lips with Your finger..
this stops the oil seal from wearing prematurely because its not lubricated.... an old mechanics trick...

best of luck

Thanks for the tips guys, got it in. What happens if I dont check the endfloat and just bolt up the flywheel?

You should read your manual once more or get someone else to build your motor!

PS. > "insertion tool"......< What do you mean Bond? We can use the term insert or install the seal in the crankcase if that is what is puzzling.

Push and pull once your finished.

You should hear it - not feel or see it (movement)

Your rockers move .006" so you get the idea

In that case, just put it back together. Wasn't clear if it was a re-build or replace. If you can, it's still a good idea to check endfloat on a used engine as it can also pick up a loose No. 1 bearing in its housing.

B 4 you put the seal and flywheel back on CHECK to see if the rear bearing is moving in the case as this is a common cause of oil leaking and no matter how many new seasl you fit it will still leak.

fixing this requires engine stripping
