Reposition Extend Chain Clevis
NOTE: Before proceeding with the repositioning of the extend chain clevis, check
the chain for any chain stretch that might have occurred. Refer to ìElongation -
Extend Chain Onlyî on page 157.
1. Return to the cab, start the engine and fully retract the boom. With the
boom horizontal, extend the boom out approximately 2 ft (610 mm) and
shut the vehicle OFF.
2. At the front underside of the outer boom (4), loosen the retract chain adjust-
ment nut (5). Back the nut off until the top of the nut is flush with the end of
the threaded clevis.
3. This step will require the help of an assistant. Return to the cab, start the
engine. Have the assistant watch at the front underside of the outer boom.
The person in the cab should slowly retract the boom until the retract chain
adjustment nut touches the clevis mounting tab (6) on the underside of the
outer boom.
