Check Track Shoe Hardware
Check track shoes periodically for loose or missing cap
screws and nuts. For shoes with missing or loose cap
screws and nuts, remove shoes and clean the mating
surface of shoes and links before tightening cap screws
and nuts. Replace cap screws when they have been
stretched to yield previously.
Operating a machine with loose shoes can cause the cap
screws and holes in the shoes and links to wear, making
it difcult to keep the shoes tight. Loose shoes can also
cause hardware malfunction and loss of shoes.
1. Clean the mating surface of shoe and links. Install
shoes.
2. Apply a light coating of oil to cap screw threads before
installing.
3. Install nuts with the rounded corners against milled
surface of link and chamfered side away from link.
Check that nuts are square with the milled surface of
link and there is full contact between nut and milled
surface. As necessary, hold the nut so it does not turn.
