SERVICE NOTES:
1).
Add bearing pad shims & spacers as required to shim boom to within 1/16" of a tight fit.
Amounts of shims can vary at each shim point. Whenever a shim is used with a pad, a
spacer must be inserted between pad & shim. No pads shall sit directly on slotted surface
of shims.
2).
Add 1440-4595 Union 76 Mega Plex to all bearing pads and bearing slide areas.
3).
The length of pad bolts depend on the amount of shims used. Bolt cannot extend past
chamfer on bearing.
4).
Bearing pad bolt torques; 3/8" bolts = 32-37 ft.lbs., 1/2" bolts = 76-86 ft.lbs.
