Illustration 4 g06128513 - Use a vernier caliper to measure the bearing assembly. The correct dimension is
80.3 + 0.0 − 0.100 mm (3.16 + 0.00 − 0.004 inch) . This measurement determines the correct angle of the rotating group. - Add shims or subtract shims (23), if necessary.
- Once the correct dimension is achieved, remove retaining ring (20), cover (21), and shims (23) from shaft (33).

Illustration 14 g00991078 - Place housing (3) into a soft jawed vise. Install Tooling (G) onto housing (3). Use Tooling (D) to measure the depth to the plate. Take this measurement in more than one location. Tighten the bolt on Tooling (G). This will push the plate and the barrel downward. Continue downward until resistance is met. Do not use force. Again measure the depth to the plate. Record the difference between the two measurements. Then subtract
0.20 ± 0.05 mm (0.008 ± 0.0020 inch) from the measurement. This is the correct thickness of shim (23). Remove Tooling (G).Show/hide tableIllustration 15 g00940683 - Remove plate (5) from the housing.
