J&M Storm Tracker 2 Track system 3660-36ST-2 - Manual (Page 13)

Pg. 13
BELT INSPECTION
The rubber track is composed of several layers of cable, similar to the cables used in automotive tires.
The most important set of cables are located about 8 mm (0.3 in.) beneath the inside surface of the track.
This set of cables, called zero degree cables, withstands track tension. Other cables, called breaker
cables, are located between the zero degree cables and the outside surface of the track. These are laid
in various angles to provide lateral support and to protect the zero degree cables.
When any of the cables are exposed to moisture by cuts or gouges in the rubber, they can deteriorate by
rusting. Because of this, any exposed cables should be repaired as soon as possible. Any damaged
zero degree cables that protrude above the surface of the track should be clipped or ground down to
below the surface of the track to prevent additional damage due to unraveling. Cuts, gouges and minor
wear on guideblocks are not expected to cause operational problems. However, a track that has two or
more consecutive guideblocks missing should be replaced since this could lead to untracking, possibly
damaging other undercarriage components.
STORAGE PREPARATION
IMPORTANT: When the track system is not going to be used for a length of time, store the tracks in a
dry, protected place. Leaving your track system outside, open to the weather, will shorten its life. Park
the track system on level ground. Block the front and rear of the belts to prevent the tracks from rolling
unexpectedly. Inspect the track system and touch-up spots where the paint has been worn away (use a
good quality primer paint).
REMOVING FROM STORAGE
1. Make sure the air spring pressure is inflated to 100 psi.
2. Inspect rubber belt for cuts or gouges and repair any damaged cables.
3. Check for missing or damaged guideblocks and replace as necessary.
4. Lubricate all grease points.
5. Repack the wheel bearings. Use Bearing Gard MK1 or equivalent lubricant.
6. Check the seal for wear and replace if necessary.
7. Check the wheel hubs and make sure the nuts are properly torque to 350 ft.-lbs.
When performing maintenance work, wear sturdy, rough-soled work shoes and protective equipment for
eyes, hair, hands, hearing and head. Follow Operator’s Manual instructions to ensure safe and proper
maintenance and repair.
Your local, authorized dealer can supply genuine replacement parts. Substitute parts may not meet
original equipment specifications and may be dangerous.
BE CERTAIN THAT ALL POWER IS SHUT OFF TO THE GRAIN CART BEFORE PERFORMING ANY
MAINTENANCE OR REPAIR WORK.
