Control Box Side Bearing
Disassembly.
1. Remove the control box side bearing assembly from the unit.
2. Remove the oil plug and drain the oil.
3. Position the bearing assembly in a vise with protective jaws or use two pieces of wood to protect the bearing housing.
4. Remove the four hex head bolts and flat washer from the end cap.
NOTE: There are shims in the bearing housing end cap. These should be saved for possible use during reassembly.
5. Remove the end cap, O-ring, bearing seal, shims, inner race and roller bearings.
NOTE: There is an O-ring on bearing end cap. Be careful not to damage it during disassembly.
6. With a bearing splitter or similar tool, remove the roller bearings from the inner race.
7. With a hammer and punch remove the bearing races from the bearing housing.
8. Inspect the roller bearings and races for wear, scoring or other significant damage. Replace if necessary.
9. Inspect the O-ring and bearing seals for wear or other damage. Replace if any signs of wear or damage are visible.
10. Clean the air vent hole.
11. Clean the parts thoroughly with clean solvent.
Reassembly.
1. Coat the outer edges of the oil seals with gasket sealant and press them into the bearing housing and the bearing end cap.
2. Press the bearing races into the bearing housing and the bearing end cap.
3. Press the roller bearings on to the inner race and place the inner race in the bearing housing.
4. Place the O-ring on the end cap, and apply oil to the O-ring.
5. Install the original shims and the end cap.
6. Torque the four bolts in a criss-cross pattern in equal steps to 13.5 N•m.
7. Lock the assembly in a vise and set up a dial indicator to check the end-play. To measure the end-play, rotate the shaft while
pushing in one direction and set the dial indicator to ‘0’. Now rotate the shaft and pull in the opposite direction while reading
the dial indicator. The end-play should be 0.025 to 0.127 mm. If the end-play is incorrect, use different shims to obtain the
correct end-play. After the correct end-play is obtained, fill the oil reservoir.
8. Place the assembly on the work bench with the vent up. Rotate the shaft by hand. The shaft should be free enough to rotate
without having to hold the housing.
CAUTION: Make sure to install the bearing assembly in the unit with the vent facing up.
