Re: Bolt Torque?
Opps.
The flywheel housing bolts should be 55 foot-pounds. Here is what Burtz says:
"Flywheel Housing/Cylinder Block Attachment Bolts
"When using an original flywheel housing that is 1/2-inch thick at the 4 lower attachment bolts, use the original 7/16 UNC × 1 1/16-inch long bolts. If using our new flywheel housing that is 7/8-inch thick at the 4 lower attachment bolts, use 7/16 UNC x 1 1/2-inch long Grade 8 bolts (McMaster Carr 92620A673). With either the original or the new flywheel housing, use the original 7/16 UNC × 1 11/16-inch-long bolts. A torque of 55 Ib-ft is recommended.
"For judging, lock washers are required at the 2 upper bolts, and we recommend
Blue Loctite Threadlocker for the 4 lower attachment bolts."
