CHECK TRACK SHOE TORQUE
Track shoe cap screw torque should be periodically
checked. If the cap screws do not meet the minimum
torque specifications, remove the shoes and clean the
mating surfaces of the shoes and links before tightening
the cap screws.
If unit is operated with loose track shoes, the cap screw
holes in the shoes and links will wear and it may be
difficult to keep the track shoes tight. Loose shoes can
also cause hardware failure and loss of track shoes.
Install all track shoe nuts with rounded edges (A) against
the link and chamfered edges (B) away from the link. Be
sure nut is properly positioned in the link so there is full
contact area between the nut and the link.
