Seal lip only onto flat surface a bit....

Clutch side is fine...

New crank seals will definitely put a drag on a crank. That's why the crank must be centered and free spinning before installing the seals.

The crank spun very freely before seal installation.... The seal on the flywheel side did not want to go on smoothly and kept trying flip "inside out" for lack of a better description...

My crank didn't smooth freely at first after all SHCS were tightened. A few taps on flywheel shaft side and it spun nice and smoothly until I installed both seals too far. After resplit ting the case with the bearings still in the bore the bearings still were tight. I'm going to press out the bearings with the seals and I've ordered new seals to start over again. So basically as soon as the seals form their seal on the shaft that's far enough I presume?

I usually put them on just a smidge further than the lip on the crank, as there's a usually a washer there and you don't want it rubbing on the washer

Here is my flywheel side after reassembly. It's noticeably tighter after that seal went in. Notice the depth that the seal body went in, it's also barely sealing up the bearing surface it is any.

Here is the clutch side before installing the seal

The crank looks centered in the case, felt ok before seals went on
