MEASURE TRACK ROLLER WEAR
Minimum used is the maximum allowable wear for
rebuilding roller tread.
Under some conditions roller wear can be uneven. If wear
is uneven, rollers may be interchanged to even out the
wear.
Measure roller tread diameter using a caliper such as the
JT05519 Special Roller Caliper from JT05518A or
JT05523 Undercarriage Inspection Service Tool Kit.
