SERVICING/ASSEMBLY INSTRUCTIONS
Proper installation of sprocket segments is critical in preventing segment loosening and subsequent loss/damage to other parts. Install segments per the following guidelines:
1.
Lubricate the bolt threads with 5P3931 Anti-Seize Compound.
2.
Bolt heads against the segments, nuts against the final drive hub.
3.
Tighten all bolts to 175 +/- 40Nm (130+/- 30lb ft).
4.
Then tighten additional 1/3 turn. This properly stretches the bolt for good retention.
CUSTOM TRACK SERVICE
Oval sprocket segments are not tape measured across the teeth to determine wear. The segment geometry and sprocket guarding does not allow for this measurement. Segment wear for oval sprocket tractors and loaders is determined by using the sprocket reuse indicator gauge. For the 953/D5 segments, the plastic gauges part no. 5P8616 (included in 6V9413 CTS tool kit). The use of the gauge to determine show when a worn sprocket can continue to be used or should be replaced is shown below.
Figure 5: Segment OK to use Figure 6: Segment should be replaced
Notice in Figure 5, the gauge indicates the sprocket can be reused, even though the tips of the teeth are cosmetically worn. The gauge is designed to show this, and thus avoid premature changing of the sprocket segments. Page 66 of the CTS handbook (14th edition) describes sprocket wear management in greater detail.
