(1) Use a minimum of one 105-9066 Hard Washer on each side of the frame. As required, use the following shims between the frame side plate and the hard washer:

105-9066 Hard Washer

Quantity ... 2

Thickness of one hard washer ... 6.35 mm (0.250 inch)

124-1440 Shim

Quantity ... 8

Thickness of one shim ... 1.5 mm (0.06 inch)

124-1441 Shim

Quantity ... 2

Thickness of one shim ... 0.51 mm (0.020 inch)

(2) As required, use the following shims:

105-9058 Shim

Quantity ... 4

Thickness of one shim ... 1.5 mm (0.06 inch)

105-9059 Shim

Quantity ... 1

Thickness of shim ... 0.51 mm (0.020 inch)

(3) Pack the bearings with 7X-7699 Grease. Use the following procedure in order to adjust the bearings:

1. Adjust bearing end play within 0.030 mm to 0.130 mm (0.0012 inch to 0.0051 inch).

2. Use the 25.4 mm (1.00 inch) gauge block in order to measure the depth in three places.

3. Tighten the six bolts (4) to a torque of 18 N·m (160 lb in) while you are rotating the roller.

4. Loosen the six bolts (4) and tighten the six bolts (4) again to a torque of 9 N·m (80 lb in) while you are rotating the roller.

5. Measure the distance between the face of the gauge block and the end of the spindle with the depth micrometer. Take an average of the three measurements.

6. Take an average of the three measurements from Step 5 minus the gauge block from Step 2. Then, add 0.20 mm (0.008 inch) to the shims.

7. Remove the gauge block and install shims (6).

8. Install the two lock plates (5).

9. Tighten the six bolts (4) to a torque of 92 N·m (70 lb ft).

10. Bend up the two lock plates (5) against the flat side of the bolt head.
