(A) 24 mm (0.95 inch) (B) 57.15 mm (2.25 inch)
Use Illustration 16 for finding the correct location to drill the holes (1) .
Drill holes to a diameter of 9.62 mm (0.38 inch). Drill holes to a depth of 8 mm (0.32 inch).
Install four 5J-3941 Spring Pins in the roller cap before the roller cap is installed on the elevator frame.
Use four 6K-5040 Hard Washers and four 0S-1606 Bolts to attach the roller cap to the elevator frame. Torque bolts to 775 40 N m (570 30 lb ft).Repeat Steps 1 through 4 for the remaining three roller caps.Note: If the bolt holes in the roller caps no longer line up with the bolt holes on the bottom of the elevator frame, the bolt holes on each cap may be enlarged to 25.4 mm (1.00 inch).Reassembly
Reassemble all components. If the paint was damaged during the repair, then reapply paint. Be sure not to paint mating surfaces of
