REASSEMBLY, FRONT GEARCASE (ADC)
1. Clean the gearcase housing of debris.
2. Replace all O-rings, seals, and worn components.

replace, press new bearing onto shaft.
NOTE
Due to extremely close tolerances and minimal wear,
the bearings must be inspected visually, and by feel.
While rotating bearings by hand, inspect for rough
spots, discoloration, or corrosion. The bearings should
turn smoothly and quietly, with no detectable up and
down movement and minimal movement side to side.
4. Install input shaft, bearing, and snap ring.
5. Press the pinion shaft seal into the gearcase, until the
seal is flush.
6. Install the LH output hub
s
into the gearcase
housing. The output hub should spin freely.
