	the left bearing, at the same time fitting the shifter yoke to the groove in the shifter sleeve. Install the double reduction shaft bearing outer race in the right side of the carrier and tap it in flush with the carrier. Install a new gasket on each side, and then install the same number and thickness of shims that were removed when disassembling, making sure the cut-out in the gasket and shims line up with the lubrication openings in the housing, Fig. 46. Assemble the bearing caps, being careful to line up the lubrication openings in the cap with those in the carrier. Install three lockwashers and nuts on each cap, evenly spaced, and tighten them securely. Install the shifter yoke shaft bushing over the shaft and tap it into the carrier. Then install the cork seal in the top of the bushing. Assemble the

Then check the tooth bearing on the ring gear for pinion depth. If the pinion is too deep the tooth bearing will be below the pitch line. If it is too shallow, the bearing will be above the pitch line. To make pinion depth adjustment, remove the pinion cage and— 1. Add shims between cage and carrier if the pinion is too deep. 2. Remove shims if the pinion is too shallow. Excessive backlash between the ring gear and

Check the bearing adjustment. Correct adjustment of the double reduction shaft bearings will produce a slight "drag" when it is turned by hand. Bearing adjustment is secured by the use of shims of .003" and .005" thickness. Assemble a new pinion cage gasket and the same number and thickness of shims that were removed when disassembling. Be careful to line up the oil holes. Assemble pinion cage and pinion assembly to the carrier with the lubrication fitting in the cage to the top right side, being careful to line up the oil holes, Fig. 47. Install three lockwashers and nuts evenly spaced and tighten them securely. Adjustment Paint the ring gear with red lead, or coat it lightly with prussian blue. Turn the drive pinion
