TM 5-3805-260-24 DIFFERENTIAL AND CARRIER ASSEMBLY (LOCK TYPE) d) If bevel pinion shaft is too near to center of bevel gear, short heel contact will result as shown. The teeth of pinion ill be in contact with toe ends of concave faces (part that makes a curve toward the inside) and the heel ends of convex faces (part that makes a curve toward the outside). To correct this, move pinion shaft away from gear by an increase of the shim thickness between pinion cage and carrier. After this is done, check gear clearance (backlash) and tooth contact again. NOTE: Several adjustments of both pinion and bevel gear can be needed before correct tooth contact setting and gear clearance (backlash) is made. Always remember that a change to gear clearance (backlash) will also change the tooth contact setting. Be sure gear clearance (backlash) is in correct adjustment before tooth contact is checked. e) After correct gear clearance (backlash) and tooth contact setting is made, remove extra prussian blue, red lead or paint from bevel gear and pinion. 30. Remove the guide bolts and install the remainder of bolts (32) to hold the pinion shaft housing to the carrier assembly. 31. Install the locks and bolts for the adjustment nuts. Install the lockwire to hold bolts (33) and the bolts for the adjustment nuts. 32. Put jaw (31) in position in the differential group and install the two bolts (34) and the lockwire to hold the jaw in position.
