    Replacing pto crankshaft seals without taking engine out?

    Is it possible to remove the crank seals by taking the pto coupling off and picking out the old ones and tapping in the new ones without removing engine?

    Yeah. I was afraid of that. There must be a groove in the crankcase they set in.

    So how much of the engine do I have to remove to get it out. Obviouslly it would be much easier to pull it appart after its out. Hoping not to have to remove all the intakes and eshaust manifolds if possible.

    Gotta split the case and all the bolts are on the bottom, so you have to pull the motor out and flip it over to split, both manifolds removed makes it much easier to pull.

    Yes you can remove the seal without removing the engine, it is rubber, just cut it a little by little it will be gone eventually. Just there is not way to out it back without spitting the crankcase. So nope.

    I am just kidding

    You have to remove everything, including the flywheel the coupler everything. It is a good to to check the crankshaft. And clean up the whole engine. If it have not been open before. You might want to consider getting the all new gasket kit.

    Sooooooooo, glad my boat is just sinking now. All that requires is a bit of duct tape here and there. Good luck on the rebuild though. Tons of great help here for that!

    I dont intend on rebuilding anything if I can help it. Compression is good, just have an air leak from rear pto seal. But we'll see......

    I'd inspect it hard while apart.
