I've changed rear main seals twice and still had a leak because of a groove in the crankshaft. Decided to try the repair sleeve from http://www.silver-seal.com/shop/engine_parts/repair_sleeves. I did the job with the boat in the water(I keep mine at sea all season). Here's some pictures. Used a ladder across the boat and ratchet straps instead of a crane or jacks.

Picture of the repair sleeve and the tool, believe I payed 30$ for the package, if it works it's a cheap fix.

Micro sleeve halfway in, just to tap it in with the tool and a hammer;-)

And we have a new sealing surface. You can still use the same size rear main seal, the sleeve does not build much. Will it work, time will tell;-) The tool that came with the sleeve was perfect to tap in the rear main seal as well.

You should double check the sealing OD on the crank, on mine it's 3.748”.

hi,

how is it going after couple hours of service of the sleeve ? Is your oil leak totally gone ?
I have received the parts for my engine. I'm planning to do the same operation soon.

Forgot to answer this one, got a tiny leak at the side where the curve on the oil pan begins, before the repair sleeve it was leaking in the middle and littlebit on the side, I'm 99.99% sure that the oil pan gasket is the cause of the leakage on the side, I changed that one last winter and probably didn't do a good enough job, I'll re-do it next winter. So I'm pretty sure that the rear main seal is not leaking anymore.

Thanks for your reply. I have also installed the sleeve on the crankshaft when I was rebuilding the engine. The rear main seal is the standard size. After 10 hours (engine break-in period) i havé noticed a tiny leak in the middle of the bellhousing. All gaskets and seals are new.
I'm in contact with the sleeve manufacturer to see what coule be the cause... Is it because i use the standard rear main seal on the sleeve? We Will see their answer.

Used the same thing on 4x4 transfer cases... Worked well for me, looks like it will for you to!

I can't imagine doing a job like that with the boat in the water!
