LOCKING PIN BUSHING REPLACEMENT - CONTINUED
FRAME BUSHINGS INSTALLATION
Bushings are installed from the inside and outside of the frame.
Lightly coat outside of new bushings (1) and bushing bore in frame (2) with 603 locktite.
Place one new bushing (1) on installation tool and center in frame bushing bore and lightly tap tool to get bushing
started and centered.
With bushing aligned, hold pressure on tool and press against bushing while it is being driven/hammered into bore until
tool bottoms out against frame.
When installing the second bushing, drive it in only until it contacts the first bushing in the center of
the frame. Do not drive it in until the bushing driver seats against the frame. Failure to follow this
caution may cause distortion of bushings and binding of locking pin. This could cause the locking pin
not to move or the bushing to be pushed out of the bore.
Ensure that seams of the bushings are not aligned with each other.
Install second bushing (1) from opposite side of frame (2). Drive in until it makes contact with first bushing.
Clean inside of bushings (1) of excess locktite that may have seeped through holes in bushings.
Allow locktite to cure for 24 hours before the locking pins are extended into bushings.
Apply a thin coat of GAA to locking pins and bushings.
Return boom and cab to operational position (TM 10-3930-675-10).
