*M1-series tank end connectors aren’t repairable, so there is no Condition Code F rating. Use
the connectors until the thickness falls below 3/16 inch. Then replace them.
**Sprocket window wear is measured from the front bushing bore.

I
n PS 614, we told you how to take care of Bradley track in the desert. But Bradleys
aren’t the only vehicles whose track takes a beating.
Heavy loads, non-stop missions, severe temperatures and abrasive sand also take
their toll on track for the M1-series tank, M88-series recovery vehicle and M113-
series vehicles.
So follow these track inspection and preventive maintenance tips to get the most
life possible out of your vehicle’s track.
Track Shoe Wear
Follow the Condition Code F wear guides below from TM 9-2530-200-24,
Standards for Inspection and Classification of Tracks, Track Components and Solid-
rubber Tires.
Condition Code F means the track shoe or pad is repairable if it’s replaced
when
it reaches this level of wear. Components and pads worn
beyond
these limits can’t
be repaired.
Follow these guidelines for component replacement and turn-in. All measure-
ments are in inches.
