Remove all the shims from assembly (1) .
Install assembly (1) and cap (2) on trunnion (3) without the shims. Tighten the bolts and maintaining equal distance on both sides of the cap.
Insert as many shims as possible into spaces (A) and (B) between the cap and the assembly.
Add two additional shims to the total shims that are used.
Install half the shims at location (A) and install the other half at location (B). Tighten the bolts to the proper torque.
This allows the assembly to move on the trunnion freely within the specified tolerance.
