When I ran my onan for the trip home the other day. about an hour into the trip, I had stopped to check things to find oil spray on the muffler. this was the longest the onan had run since I have had the motorhome.
I read plenty of posts, and I hope I have it figured out. I am replacing the front seal, the oil filter bracket gasket and the LOP switch.
I just wanted to share my experience, in case anybody out there is trying to do the same.
The job seemed really easy. and I think it is. Tin came off easy to access everything. I did run into a problem removing the flywheel.
a couple posts showed harmonic balance pully puller being used. I destroyed two of them. with zero luck getting the pully to budge.

as you can see, I worked the heck out of them. and this was a process over a couple evenings. I cranked up the tension. and let them sit overnight.
anyway to make this short, I bought a $14.00 timing gear puller from O'reilies autoparts. and it popped it right off. It fit nice, and worked well. I had it off in about 2 minutes using the "timing gear puller" I just had to use 2ea 3/8 in bolts, because the bolts that came with the puller were one size too small.

it is actually has a lifetime warantee, and you can "rent" it. so I could bring it back and get my $14.00 back.
now to figure out how to get the front seal out.
