Note: This procedure will require a clear space of
approximately 16 feet at the front and rear of the vehicle.
2. Park the vehicle on a hard, level surface. Move the
boom to a horizontal (level) position. Extend (or retract)
the boom until the boom is extended approximately
two feet (610 mm). Move the quick attach to the
horizontal position. Place the travel select lever in
the (N) NEUTRAL position, place the neutral lock
lever in the (N) NEUTRAL LOCK position, engage
the parking brake and shut the engine OFF.
3. Remove one thumbscrew (Fig. 3-1, 1), one internal-
tooth lockwasher (2) and one flat washer (3) holding
the rear cover (4) to the rear of the outer boom (5).
Lift the rear cover straight up until the capscrew in
the top of the cover clears the hole in the top of the
outer boom. Remove the cover from the outer boom.

4. At the rear of the boom, measure the amount of
threads protruding beyond each elastic locknut
(Fig. 3-2, 1), and record that measurement for
reassembly. Loosen the extend chains by loosening
the two locknuts located at the rear of the inner
boom. The locknuts must remain fully engaged with
the threads of the extend chain clevis’.
