Hey Spare - I see you're on right now - or anyone else.....

I cleaned up the rusty, pitted shaft and installed new seals, but still leaked out the weep hole. The shoulder of the cam shaft isn't beveled, so it's hard to get the seals on, especially while fighting the rest of the fit (particularly where the casting meets the oil pan gasket at the bottom without scraping off all the RTV).

I buggered up the outer (water side) seal getting it on. Is there a trick to getting the thing back together without wrecking the new seal again?:head:

I think I'll sleeve the shaft with a Speedy Sleeve this time to be sure I have a good surface for the seal to ride on - of course that's going to make the seals even harder to get on.

I appreciate the help.
 
speedy sleave should help, pull the dowel pins out of the cover/block on the front of the engine, this should allow you to move the cover around a little bit more, after you get it in place, use a screwdriver shaft to align the cover thur the dowel holes(the holes go thru the cover), after you get it snugged in place, you can install the dowels thru the cover with a punch
 
Thanks Spare

SpeediSleeve - Tested sleeve retaining compound, but, even with the activator stuff it didn't set up very well, and the pitting in the cam was too deep, so I set the sleeve with JB weld.

It took three days, but I pulled the locating pins (a little Kroil, some harfing up & down with vice grips, more Kroil, etc. etc.). I almost gave up, but finally saw some little bubbles when I was working the vice grips and knew I had it.

Man - you were a great help - got it back together - the seal looked perfect and it ran without a drop of coolant leaking. Got it done just in time for a big family visit and was able to pull the kids around on the donut, which made their summer (they talk about their visit and the donut all year:nice:
Now I can get on with some cosmetic work and setting the boat up better for fishing around here.

Thanks again - you're what makes this site great.
