BOOM ARMS 6.2
Removal
1 Lower the boom arms and shut off the engine. Turn
the ignition key to the “RUN” position and cycle the
boom and tilt controls to relieve hydraulic backpressure.
Lock the boom lift control in the float position.
2 Return the key to the “OFF” position and engage the
parking brake (raise the restraint bar).
3 Remove the quick - tach assembly from the boom
arms. (See Section 6.1)
4 Disconnect the hydraulic hoses between the boom
arm and reservoir tanks. Cap the open hose ends to pre-
vent contamination. (fig. C3601)
5 Fasten chains or lifting straps with an adequate
capacity to sustain the weight of the boom arms. Most of
the weight is at the front of the boom arms. Attach one set
of straps as close as possible to the front, (fig. C1844),
and the other set approximately half way toward the rear.
6 Using an overhead hoist, raise the boom arms enough
to take the weight off of the lift cylinders. Remove the
bolts from the pivot pins in the lift cylinders that are
mounted in the boom arms. (fig. C3603)
7 Remove the pins by reaching between the ROPS and
the boom arm and pushing the pin out toward you. Take
care not to let the lift cylinder fall on your hand.
8 Remove the bolts from the upper rear boom arm
pivot pins mounted through the main frame. (fig. C3604)
9 Remove the pivot pins using an appropriate drift
punch and hammer. Use care, do not broom up the end of
the pins.
10 Raise the boom arms enough to free from the loader
and remove them.

Installation
1 Upon installation follow the above procedure in the
reverse order.
2 Replace any worn or gouged pins and bushings
3 All stationary bushings should be coated with anti -
seize compound to assist ease of future disassembly. Do
not get the anti - seize compound on moving or pivoting
parts. The compounds contain abrasives that may cause
premature wear of pivot pins and bushings.
4 Torque the hydraulic hose fittings as outlined in the
Section 1 Hydraulics torque chart page 1-35.
