Hello,
I put the case together this weekend with the cam and crank! It looks and feels great! (IMG:style_emoticons/default/biggrin.gif) But I had trouble putting in the main seal (on the fan end). I used a rubber mallet and a roll of electrical tape to tap it in. The roll of tape helped because it gave a flat surface to hit on, with the hole of the roll letting the end of the crank come through. None the less, I managed to tear the seal and now need to get a new one! Does any one have some advice so I don't waste another seal??? One thought I had was to back off all the case bolts/nuts to get a bit more space and then retighten the bolts/nuts. Cheers Nate PS: attatched picture shows engine case assembled from flywheel end. Attached image(s)

I make sure the seating surface is really really clean and I put some grease on the mating surface of both the case and the seal. I get a 2x4 that spans the seal, and tap it in. Of course I will hit the 2x4 not sqaurely which will cock the seal in its bore, but after a few tries, it goes in. I get the seal flush with the edge of the case with the 2x4, then carefully tap it until it seats around the edge of the seal with a socket extension. I also grease the inner lip of the seal so that the flywheel doesn't tear it during the first startup.
Has worked well so far with the seals I've replaced. -Chris |

Chris is right. Done it this way and it works well.
Good luck. |

Thanks!
I'll order up a new seal and try it with the grease and 2x4. Cheers, Nate |
