Component Evaluation EEC-0131 V1.1
Component Evaluation
4. Failure in the electrical system can result in intermittent or undesirable actuation
of the control valves. When any malfunction occurs, the master switch must be
turned OFF until the problem is resolved.
Rotation Bearing and Gear Box
1. A simplified method can be used to check for excessive backlash between gear
teeth on the exterior of the rotation bearing and pinion drive gear on the gear
box. The method involves placing a piece of tablet paper on the gear, then rotate
the boom to check for proper alignment and clearance. Remove the paper from
the other side; the paper should only be partially cut from the gear teeth.
2. If the gear box is too loose or too tight:
A. Loosen the bolts that connect the gear box to the turret box.
B. Rotate the eccentric ring to move the gear box closer or further from the
bearing.
C. Once the gear box is in positon, tighten the bolts that hold it in place.
3. Bearing bolts must be torqued to values listed in the Parts Manual-Turret/Bearing
Assembly.
4. Rotation bearing bolts should be checked after the first 10 and 40 hours of
operation, and on a monthly basis thereafter.
Filters
1. Both the return and pressure filter elements should be replaced after the first 20
hours of operation, and every 500 hours thereafter or when indicated. NOTE:
new units may require more frequent filter element changes due to normal
wear-in of new parts.
2. If the dirty-filter gauge on the return filter housing at the reservoir indicates the
filter is dirty with the engine on high speed and the filter housing is warm to the
touch, the element must be replaced immediately.
