6 - WORKING OPERATIONS
Partially controlled wear factors
Speed
Unnecessary speed can cause a higher wear rate on pins, bushings and sprockets. The faster the speed, the faster
the wear rate. High reverse speed accelerates bushing and sprocket wear. Reverse speeds are faster than forward
speeds. Wear rate is a function of speed and distance traveled not just hours worked.
Impact
High speed will increase impact loading when there is low grouser penetration on hard surfaces or when working in
rock.
Impact can cause structural problems such as bending, cracking or breakage of components. This can also affect pin
and bushing retention and bushing cracking. Fractures can be caused by a worn chain.
Turning
Wear rate increases with increased turning. Turning increases interference loads between moving components.
Turning in reverse accelerates bushing and sprocket wear due to increased loads transferred from the rotation of the
bushings against the sprocket in reverse.
Track slip
Wear rate on all components increases when tracks slip. Track shoe grousers are affected due to increased sliding
between the grouser and the ground.
Favored side operation
Wear rates will increase on all components when only one side of the machine is favored. Wear increases as more
power is applied to the favored side. More packing and slippage will occur on the favored side that will result in an
increased wear rate.
Reverse Operation
Avoid excessive use of reverse operation. This is nonproductive use of the machine that accelerates bushing and
sprocket wear. Most speeds are faster in reverse than forward.
Dozing
Dozing shifts the machine weight to the front causing a faster wear rate on the front rollers and idlers.
Ripping
Ripping will shift the machine weight toward the rear causing a faster wear rate on the rear rollers. During severe
applications, the sprockets and track bushings wear much faster.
