MEASURE TRACK CHAIN PITCH
Maximum used is the maximum allowable wear for turning
pins and bushings.
1. Remove slack by putting a wooden block between
sprocket and chain; then slowly move machine in
reverse to tighten chain.
2. Measure pitch across several four-link sections as
shown, except section on either side of master pin, to
find average chain wear. Use a tape measure such as
the JT05520 Metric Tape from JT05518A or JT05523
Undercarriage Inspection Service Tool Kit.
