diameter. Insert jacking screws (1/4-20UNC grade 8) with
at least 1.5 inches of thread length into each of the three
tapped holes to force the ring gear out. Be sure and alter-
nate between the jacking screws to keep the ring gear from
becoming misaligned in the bore. The screws will push
against the outer race of the main bearing. This bearing
will have to be replaced afterwards.
