Removal
1. Check that the stabilizer is fully retracted and the float
removed.
2. On the stabilizer end, tag and remove the top wear pads
and shims from the outrigger beam.
NOTE: The outrigger wear pads and shims are adjusted at
the factory. Tag the shims and wear pads during
removal to ensure proper reinstallation.
3. Extend the outrigger beam slightly so that a lifting strap
(Figure 7-4) can be attached to the outrigger beam.
NOTE: To prevent nick and gouges to the bottom of the
outrigger beam, do not attach chains to the
outrigger beam.
4. Remove the hydraulic lines from the base of the extend
cylinder (Figure 7-1).
