Introduction
Use the procedures that follow to check the vertical movement and the circular movement of the swing bearing. Two dial indicators with magnetic bases are required for the procedures.Required Tools
Table 2
Tool Qty Description
A 2 Dial Indicator Procedure To Measure Vertical Movement Of The Swing Bearing
Place the machine on level ground.
Empty the bucket.
Position the upper structure parallel with the tracks.
Inspect the static torque of the bolts in the swing bearing to make sure that the bolts are tightened properly.
Set the torque wrench to a torque value of 800 N m (590 lb ft).
Make a mark on the head of the bolt that is relative to the carbody or the bearing race.
Apply the specified torque to the bolt.
If the head of the bolt does not move, the torque is within the specification.
If the head of the bolt moves, replace the bolt.

(D) Inner race of the swing bearing
(F) Carbody
Refer to Illustration 1. Position dial indicator (A) between the carbody and the outer race of the swing bearing (C). Position dial indicator (B) between the carbody and the outer race of the swing bearing (C).Note: Position the dial indicators at the front center of the carbody and at the rear center of the carbody.
Illustration 2 g02173683
Position the machine as shown in Illustration 2.
Adjust both dial indicators to "zero".
Illustration 3 g02173685
Position the machine as shown in Illustration 3. The angle between the ground and the track should be approximately 15 degrees.
Calculate the total distance of movement between dial indicator (A) and dial indicator (B). Record the total distance movement of in Table 1.Note: This measurement is one of three measurements of the vertical swing bearing movement to be used in Step 14.
Reposition the machine as shown in illustration 2.
Note the distance movement of both of the dial indicators. Calculate the difference for each dial indicator and the measurement at the zero point that was measured in Step 7.Note: The difference calculated for each dial indicator should be less than 0.05 mm ( 0.002 inch). A greater distance may indicate that the dial indicator has moved out of the original zero position This greater distance also indicates that the measurement from Step 9 is not a valid measurement and more vertical swing bearing movement measurements are necessary. Repeat Steps 6 through 11.
Remove the dial indicators. Rotate the upper structure three times in a clockwise direction. Rotate the upper structure three times in a counterclockwise direction.
Repeat Steps 5 through 12 three times.
Calculate the average of the values that were recorded in Step 9. Compare this average to the service limit specifications are shown in Table 1.Procedure To Measure Circular Movement Of The Swing Bearing
Place the machine on level ground.
Empty the bucket.

(E) 1000 mm (39.4 inch)
Position the upper structure parallel to the tracks. Refer to Illustration 4 for the correct position of the boom, of the stick, and of the bucket.
Stop the engine.
