No pressing was ever necessary to install bearings into case or on crankshaft.

If you are using a torch, be sure to stay away from your newly installed seals. Rotate torch in a circular manner around the bearing bore. It doesn't have to be scorching hot to do the trick. Install bearings until fully seated in bearing bore.

You can always use an oven or, better yet, a bbq grill to do the heating as well.

Use something similar to Yamabond or Loctite anaerobic sealer. Definitely not silicone.
THANK YOU! Your method seems a lot easier than the manual. Had not thought about heat gun, will try that.
