NOTE: Arbor Discs 6732 has different step diameters to fit other axles. Choose proper 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.
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.
9. Select a shim equal to the dial indicator reading plus the drive pinion gear depth variance number etched in the face of the pinion gear. For
example, if the depth variance is -2, add +0.002 inch to the dial indicator reading.
NOTE: If an oil slinger is used behind the inner pinion bearing, deduct the thickness of the slinger from the dial indicator reading and use that
total for shim selection.
