Crank seal question SLT780
Can the crank seals be replaced without splitting the cases?
Can it be done with the engine still in the ski?
Anybody want to trade my Cylmer 92-95 manual for a "96 up manual so I can stop asking so many dumb questions?

Don't hope. Do a pressure test on the cases. Plug up all opening air tight. Then add 9 lbs of vacuum or pressure to the pulse line fitting and see how long it holds for. It should hold for a few minutes. If not, you got a leak and will be running lean. (Very bad)

Crank seals usaully dont go. But its always better to be safe than sorry.

If you are that far into the motor already, you are about 90% of the way there. take the extra hour and $40 and install new seals. It would be foolish not to.

As long as you keep track of the shims when you take it out, it is a drop in and go affair. splitting the cases is about 30 bolts. you will need to clean them and buy some good sealant, and of course have a torque wrench, but very straightforward.
