Re-Torquing Of Track Shoe Cap Screws
Failure to maintain correct track shoe cap screw torque
will result in serious damage to the undercarriage
components, shorter life expectancy, and it will void the
Manufacturer’s warranty on the undercarriage
components. Each inspection and re-torquing should be
documented by completing a Service Report for each unit,
placing a copy of this report in the machine file, and
forwarding a copy to the manufacturers attention.
