2. Insert assembled height gauge components, rear bearing and screw into axle housing through pinion bearing cups.
3. Install front pinion bearing and Cone 6740 hand tight.
Gauge Tools In Housing-Typical
4. Place Arbor Disc 6732 on Arbor D-115-3 in position in axle housing side bearing cradles. Install differential bearing caps on Arbor Discs and
tighten cap bolts to 41 Nm (30 ft. lbs.).
NOTE: Arbor Discs 6732 have different step diameters to fit other axle sizes. Pick correct size step for axle being serviced.
5. Assemble Dial Indicator C-3339 into Scooter Block D-115-2 and secure set screw.
6. Place Scooter Block/Dial Indicator in position in axle housing so dial probe and scooter block are flush against the rearward surface of the pinion
height block. Hold scooter block in place and zero the dial indicator face to the pointer. Tighten dial indicator face lock screw.
7. With scooter block still in position against the pinion height block, slowly slide the dial indicator probe over the edge of the pinion height block.
Observe how many revolutions counterclockwise the dial pointer travels (approximately 0.125 inch) to the out-stop of the dial indicator.
Pinion Gear Depth Measurement-Typical
8. Slide the dial indicator probe across the gap between the pinion height block and the arbor bar with the scooter block against the pinion height
block. When the dial probe contacts the arbor bar, the dial pointer will turn clockwise. Bring dial pointer back to zero against the arbor bar, do not
turn dial face. Continue moving the dial probe to the crest of the arbor bar and record the highest reading. If the dial indicator can not achieve the
zero reading, the rear bearing cup or the pinion depth gauge set is not installed correctly.
