CLEANING AND INSPECTING GEAR
CASE (w/o Reverse)

NOTE: Whenever a part is worn excessively,
cracked, or damaged in any way, replacement is nec-
essary.
1. Wash the gear case halves and unsealed bearings in
parts-cleaning solvent.
2. Inspect the gear case halves for trueness, scoring, pit-
ting, scuffing, or any imperfections in the casting.
3. Inspect all threaded areas for damaged or stripped
threads.
4. Inspect the bearing areas for cracks or excessive
bearing movement. If evidence of excessive bearing
movement is noted, replace the component.
5. Inspect the bearings for wear, scoring, scuffing, dam-
age, or discoloration. Rotate the bearings. Bearings
must rotate freely and must not bind or feel rough. If
any abnormal condition is noted, replace the bearing.
6. Inspect the planetary and ring gears for wear, cracks,
or chipped teeth.
7. Apply a light film of Arctic Cat ACT Drive Fluid to
the unsealed bearings prior to assembling.
