 TM 9-2815-226-34-1
e. Measure thrust flange wear at four points 90 degrees apart. If distance between thrust flange and rear
counterweight does not exceed 3.006 in. (76.352 mm), flange wear is acceptable.
f. If wear exceeds 3.006 in. (76.352 mm), shaft must be ground to restore flatness.
g. If after grinding, dimension does not exceed 3.008 in. (76.403 mm), standard thrust rings may be used.
h. If dimension exceeds 3.008 in. (76.403 mm), flange must be reground to accept 0.010 or 0.020 in. (0.254 or 0.508
mm) oversize thrust rings, i. Regrinding must clean up a minimum of 90 percent of thrust surface and result in
maintaining installed crankshaft end clearance below 0.015 in. (0.381 mm).
