Rear main seal

I've got everything apart and the upper seal doesn't want to move. I'm using a small punch and have tried tapping both sides. Does this sometimes happen or do I need a bigger hammer?

I had the same problem with my seal, make sure you don't damage or score the seal cavity. I used some penetrating oil and tapped on both sides until it broke lose. It took a while, but eventually it slid out. When you install the new seal, be sure to oil it well and install it in the correct direction.
Good luck

Had to loosen all the mains, seal slid right out. Also replaced the oil pump, timing chain, gears and cover. Took it out last night for about an hour ride and no leaks so far Thanks for the help. Now I need to fix the exhaust leaks.

Easy job. How clean did you walk away from it?

CLEAN!!!! I pressure washed top to bottom and still made a mess but not as bad as if I hadn't washed it first.

I drained my oil the night before to let the oil drip down, I have a lift in my garage, and still made one hell of a mess.

Other than the clean up, it was a easy job.

You must loosen three or four main bearing caps to get the top seal out. Just loosen a little and let the crank come down a fraction.

I have done a few rear mains some come out easy others not so easy. One thing I wanted to point out, is that if you are hitting it with a punch make sure you are hitting against the metal ring which is molded into the seal. If you are only hitting against the rubber material, it will be difficult to break the seal loose. As others have said you may need to loosen the crank to get the old top half out. Just be patient and take your time.
