Inspection of Rotation Bearing Clearance
1� It is not feasible to make an analysis of the condition of the rotation gear while it is on the unit� There
are too many variables involved for this to be accurate�
2� A bearing may cause a problem in the operation of the Boom Truck or the confidence of the
operator long before it would be deemed structurally unsafe�
To properly check the radial clearance of the rotation gear, it must first be removed from theBoom Truck
and placed on a heavy flat table� Remove all dirt and grease from the outside of the gear and secure it to
the table with clamps, assuring that the inner raceway rotates freely after clamping it to the table�
As shown in the figure below, attach a large “C” clamp in position #1, and tighten just enough to take all
the slack out of the raceway� Install a dial indicator as close to position #1 as possible, and set it to “0”�
As shown in the figure below, attach a large “C” clamp in position #1, and tighten just enough to take all
the slack out of the raceway� Install a dial indicator as close to position #1 as possible, and set it to “0”�
Remove the “C” clamp and attach at clamp location #2 and again tighten just enough to take up the
slack in the two raceways� Look at the dial indicator, noting the amount of change in the reading� This
measurement is the radial clearance of the bearing� The following bearing clearances should be observed�
