80in front crankshaft seal?

[Summiitt]

Is the front crankshaft output seal a hard one to replace? My 52 80in leaks about the size of a 20c piece after a 50+km run, not sure if I should bother replacing it or not as I don't do allot of Kays in the wee truck?

Hi

I've never done that job with the motor in situ . Is there enough room behind the front crossmember to remove the crank pulley ? The hardest bit is removing the pulley off the crankshaft .
