( 2 ) TS - Improved Wear Material
( 3 ) NTS - Standard MaterialSegment Installation
Proper installation of the sprocket segments is critical in order to prevent loosening and subsequent loss of damage to other parts. Use the following guidelines to install the segments.
Lubricate the threads with 5P-3931 Anti-Seize Compound .
Ensure that the washer is against the final drive hub. The washer should not be against the segment.
Tighten all bolts on any one segment to the value in table 2.
Then, tighten the bolts by an additional 1/3 turn. This stretches the bolts properly for good retention.
