M59 main seal leak

[Hysert]

HI Guys. Got a main crank seal leak at the pulley side! Just started, bearing and crank a fine!! Just wondering how to lock the crank to loosen the 46mm pulley nut to remove it and replace the seal?? Thanks

Normally you can use an impact, or just whack a bar and it will loosen right up.
Strap wrench holding pulley, or if that's not an option, pull the starter and have someone hold a bar on the flywheel teeth.
