Seating the crank & Installing seals
Posted: March 13th, 2011, 10:44 am
Everyone has their own procedure, heres how I do it.
I never have a camera on hand, but the phone was there.
I use these aluminum tools to pull the crank into the cases, they shoulder on the ends of the shafts, or the washer surfaces.
The large seal installer is 2 pieces, the outer piece also seats the output shaft seal
The stator side case has the crank seated


I wet the outside of the seal with wd-40, grease the inside.


Here is the seal seated perfectly square and reccessed so it wont burn on the flywheel by being only flush with the housing

Drive Side goes the same way, The driver here has an hourglass shape on the bottom that holds the seal by the lip, that way it wont be pinched or folded and its not trying to start crooked or get away on ya.

A cylinder stud threaded into the crank works to pull the seal in and seat the crankshaft (done before the seal install, sorry, no picture.

The same procedure for the seal happens at the sprocket side, I don't pilot the seal by the lip there, but the tool is made narrow to not contact the ribs arround the inner or outer circumfrence of the seal.
Hope this helps some guys.
