How to Fill-Out CTS Inspection
Report Using Caterpillar Form
as Example*
1. Customer and Machine Information
2. Component History — This section
should be filled in from history records
prior to the inspection. It should reflect
date(s) or meter reading(s) which will
allow calculations of hours on the
parts. Lines are provided next to the
track roller positions to enter a flange
type for each roller. Use “S” for single
flange and “D” for double flange as
installed on the machine.
3. Inspection Information — Meter
reading is used to determine hours on
parts. Hours per week is for expected
future usage of the machine and is used
for projecting and scheduling alterna-
tive actions.
The notes section is for any additional
information pertinent to the inspection
which is not on this form. Major rec-
ommendations to the user may also be
included on the reverse side of the CTS
Inspection Form.
Record the measurement of each com-
ponent to the closest 0.01" (0.1 mm) for
the left and right side of the machine.
4. Calculated Data — Hours on Wear
Surface is very important data and may
be calculated by subtracting the hours
or date installed from the current hour
meter reading. Without knowledge of
the component hours, no projection of
total potential will be possible even
when percent worn is determined.
Percent Worn is obtained by using the
measurement and the appropriate
impact or allowable wear ratings from
the wear chart portion of this
handbook.
Total Potential Hours to Service Point
(100 percent worn) are calculated by
dividing the hours on wear surface by the
percent worn. This will give the potential
to the service limit assuming constant
conditions. It may not be reliable using
percent worns less than 30 percent.
Total Potential Hours to 120 percent
Worn are calculated by multiplying the
total potential hours to 100 percent worn
by 1.2.
A line is provided to show the calcu-
lated average of track roller data. This
line is used to determine track roller
swapping considerations.
