BUSHING 4B2065 1F2246 - Caterpillar

1. Remove the cover from the bevel gear compartment (1).2. Remove oil lines (2) from each hub.3. Fasten a hoist to the bevel gear shaft for use as a support.4. Remove the bolts from each bearing cage (3). Install two 1/2"-13 NC forcing screws (4) in the bearing cage. Tighten the forcing screws evenly until the bearing cage is free of the bevel gear case. 5. Remove nuts (5), bolts, and locks that hold the shaft to the gear. 6. Move the bevel gear shaft (6) into the steering clutch compartment on the right. Fasten a hoist to the bevel gear shaft and remove it. Weight is 80 lb. (36 kg). 7. Fasten a hoist to the bevel gear (7) and remove it from the bevel gear compartment. Weight is 57 lb. (26 kg).Install Bevel Gear And Shaft
A bearing adjustment for the bevel gear shaft can be made with the transmission in or out of the machine. A more specific preload can be put on the bearings with the transmission out of the machine. The following procedure is for putting preload on the bevel gear bearings with the transmission removed. See BEVEL GEAR AND PINION in TESTING AND ADJUSTING for the application of preload on the bevel gear bearings with the transmission in the machine. 1. Fasten a hoist to the bevel gear shaft (1). Put the shaft into position through the steering clutch compartment on the right side. Move the shaft to the left through the bearing cage bore. Install the bevel gear shaft (5) without the bevel gear (3) unless the transmission has been removed.2. Install the right bearing cage (4) with a full package of shims. Install the bolts (7) that hold the bearing cage. Tighten the bolts evenly.3. Install the left bearing cage (2) without shims. Install two bolts (6) without lockwashers, 180° apart. Tighten the bolts evenly while the shaft is slowly turned until a torque of 60 to 80 lb.in. (6.78 to 9.05 N m) is needed to turn the shaft. To find the torque needed to turn the bevel gear shaft, weld a strap of metal across the nut for the steering clutch hub. Weld a small nut in the center of the strap. Install the nut and strap on the end of the bevel gear shaft. Put a torque wrench on the small nut.4. Measure the distance between the left bearing cage and the face of the bevel gear case with a feeler gauge. Make a measurement at the location of both bolts. Make sure the distance is the same all around the bearing cage. 5. Remove the left bearing cage. Install an amount of shims with the same thickness as the measurement in Step 4. Install the left bearing cage and its bolts. Check the torque needed to turn the bevel gear shaft again to make sure that it is between 60 to 80 lb.in. (6.8 to 9.06 N m). 6. Remove the right bearing cage. Move the bevel
