Learn From My Mistake!!

hughes:
Guy's I spent the week pressing out the bearings in the engine cases. I was using a hydraulic press to remove and install the bearings. Got all the bearings installed accept the crank bearings and seals. Saved those for last. Went to installed the first crank seal using the hydro press and used just alittle to much pressure an pushed the seal through the other side. Busted the lip off thats hold the seal from popping out in the clutch area. Bone Head Mistake. The other seal went in easy using the large socket and tapping it in with the hammer. I think I can fix it with JB Weld. it's a no stress or load area it just keeps the seal in place. Wish me luck.

machine:
Hughes, do you think you could have it TIG welded???

hughes:
I used jb weld on it today. The good thing is the lip fits perfecty back where it came from. If you tap it back in with a small hammer it fits so good you need a small pick to remove it. So I put jb weld on it and tapped it back in place and used jb on the outside dia. of it. I think it will hold.

Johnniespeed:
The J-B weld is good stuff, but if it doesnt hold, there are many excellant welders and machinists out there. I am very sure someone could fix it.  I would try J-b first , there is almost no stress on the seal. I am guessing engine vibration would be the concern here.   Also you can keep an eye out for a trashed engine to grab a case half .   Is yours a 87 ?

FIVE-HUNGE:
I once saw the cases from a Pro Circut race bike. the lips you are talking about were removed for easy crank seal replacement. Somebody correct me if I'm wrong but I think Kawasaki is the only bike to have these lips for the crank seals.
