Anyone replace their rear main seal themselves? 850 1994

Hi Dick,

I recently did this on my '95 850T. I mostly followed the procedure in the Volvo shop manuals (echoed in the Haynes manual) which was generally to support the engine, drop the sub-frame on the drivers side, (loosen on the passenger side,) lower the engine down, and pull the transmission off. Rather than the transmission jack, I landed it onto a 2x12 set up as a fulcrum. Crude, but it worked. It also helped to have an assistant who also knows cars.

I replaced the transmission output shaft seals too, not because they were leaking, but because I had the tranny out and it's easy to do when it's out. Also changed the fluid.

I ended up building an engine hoist out of lumber with a long threaded rod to lower the engine with. Crude, but reasonably effective. Ends of a 4x4 rested on 2x4's set on the inside of the fender by the top of the strut towers.

Hardest part was getting at the bolts on the rear engine mount - just difficult to reach and get a wrench on properly. If you've done other cars, this won't be anything particularly new.

A lot of the induction system (air filter, induction pipes, etc.) all had to come off to be out of the way.

Only problem I have is that somewhere in the process, I developed a vacuum leak that I'm still trying to track down. It keeps setting my Check Engine Light with a 3-1-5 trouble code (EVAP). Many of the hoses were getting old and cracked, so I'm suspecting it's one of them. (Tried to replace them, but the dealer didn't stock the hose, and NAPA was less help...) One of these days I'll find it...

Good luck!
