Trunnion Adapters

The trunnion pins should be supported to within 1/16 inch of the trunnion adapter plate. See the "A" dimension in the table for the width of the mounting plate. The maximum distance between the trunnion pin support mounting surfaces should be less than or equal to the "A" dimension plus 0.13 inches.

The trunnion pins should be ground to the "D" diameters shown in the table. The trunnion pins should be made from steel with a hardness greater than 30 HRC and a yield strength greater than 60,000 psi.
