I am installing the heavier flywheel on our 08 150 r. I took out the flywheel nut no problem with an impact but i cant hold the flywheel still to be bale to torque it down. When in gear and brakes pressed it turns, resistance increases but wont tighten and rear wheel turns. What are some tricks you guys have used to hold the flywheel still while you torque, after all i cant see why it is so hard if it is only torqued to 47ftlbs (dealer recommendation). I want to to finish this today to get out there this weekend so please let me know your tricks asap. Thanks.
