TM 5-3805-260-2429.To check the tooth contact setting between thebevel gear and pinion after the gear clearance(backlash) and the bearing preload adjustmentshave been made, use the following procedure:a)Put small amount of prussian blue, red leador paint on be el gear teeth. Turn pinion andcheck marks made on bevel gear teeth.b)With no load, correct tooth contact settingwill be as shown. The area of contact startsnear toe of gear and goes about 30% up thelength of tooth. With this setting when load isput on gear, it will be over the correct area ofteeth.c)If bevel pinion shaft is too far away frombevel gear, short toe contact will result asshown. The teeth of pinion will be in contactwith toe ends of convex faces (part thatmakes a curve toward the outside), and topedge of heel end of concave faces (part thatmakes a curve toward the inside). To correctthis, move pinion shaft toward gear by adecrease of shim thickness between pinioncage and carrier. After this is done, checkgear clearance (backlash) and tooth contactagain.3-244
