Flipping a Worn Boom
Service Interval: Every 25 hours—Inspect the boom
for wear.
Inspect the bottom of the boom for wear. If it is worn,
complete the following:
Note:
A boom is worn when grooves from the chain
are deep enough that the link rollers contact the boom.
Note:
If you have already flipped the boom once,
replace the boom when both sides are worn.
1. Park the machine on a level surface, disengage
the auxiliary hydraulics, engage the parking
brake, and lower the loader arms.
2. Shut off the engine and remove the key.
3. Loosen the jam nuts and move them to as close
to the head of the tensioning bolts as possible
(
Figure 11 ).
4. Remove the chain from the drive sprocket and
boom.
Note:
Use a hoist to lift the chain.
5. Remove the boom, flip it over so the bottom
becomes the top (or if you have already flipped
it once, replace it), and install the boom again
(
Figure 11 ).

6. Install the chain over the drive sprocket and idler
wheel.
Note:
Use a hoist to lift the chain.
7. Adjust the tensioning bolts until there is
approximately 2.5 cm (1 inch) of slack between
the bottom of the boom and the chain. Tighten
the jam nuts.
Note:
Ensure to adjust the jam nuts on both
bolts evenly.
Replacing the Digging
Teeth
Service Interval: Before each use or daily—Inspect
the boom for wear.
Due to the high amount of wear placed on the digging
teeth, you need to replace them periodically.
To replace a single tooth, remove the bolts and nuts
securing the tooth to remove it, then install a new
tooth in the same position. Torque the bolts securing
the teeth to 37 to 45 N∙m (27 to 33 ft-lb).
