Final Drive Wheel Bearing Adjustment Short Heel Contact Setting c. If bevel pinion shaft is too far away from bevel gear, short toe contact will be the result as shown. The teeth of pinion will be in contact with toe ends of convex faces (part that makes a curve toward the outside), and top edge of heel end of concave faces (part that makes a curve toward the inside). To correct this, add shims under pinion bearing cup. After this is done, check gear clearance (backlash) and tooth contact again. d. If bevel pinion shaft is too near to center of bevel gear, short heel contact will be the result as shown.
The teeth of pinion will be in contact with the 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, remove shims from under pinion bearing cup. After this is done, check gear clearance (backlash)and tooth contact again. Wheel Bearing Adjustment (1) Hub. (2) Washer. (3) Nut. 1. Tighten nut (3) slowly to 135 NҐm (100 lbҐft) while hub (1) is turned to put the bearings in position. NOTE: Several adjustments of both pinion and bevel gear can be needed before correct tooth contact and gear clearance (backlash) is made.
Always remember that a change to gear clearance (backlash) will also change the tooth contact. Therefore, be sure gear clearance (backlash) is in correct adjustment before tooth contact is checked. e. After gear clearance (backlash) and tooth contact are correct, remove extra Prussian blue, red lead or paint from bevel gear and pinion. 3 2 Wheel Bearings (2) Washer. (3) Nut. 2. Loosen nut (3) completely and tighten it again to 50 L 5 NҐm (37 L 4 lbҐft). 3. Bend washer (2) to hold the nut in position. Power Train Testing And Adjusting 27
