UNDERCARRIAGE
FOR DOZERS
WORLD-CLASS PERFORMANCE PLUS LOW OWNING & OPERATING COSTS
The longer your undercarriage lasts, the lower your total cost of ownership. Because Cat® undercarriage is designed and manufactured by Caterpillar to specifically match your machine requirements, your Cat dealer can provide you with inspections and services that ensure every component lasts as long as possible before replacement.

Operation Checklist
Proper shoe selection and smart operation will make your undercarriage work better and last longer. Here are four ways to get the most from your Cat undercarriage investment.
Always use the narrowest shoe possible
while still allowing for adequate flotation
Minimize high operating speeds
in nonproductive situations, especially in reverse
Alternate turning direction
since turning in only one direction wears out one side of the undercarriage faster than the other
Monitor track spin
which reduces production while increasing wear on all undercarriage components
Maintenance Tips
Practicing undercarriage preventive maintenance is an efficient way to extend undercarriage wear life and avoid undercarriage component failures. Below are some key practices you can follow.
Call your parts & service representative
for expert advice and service
Adjust the track for correct tension
in its working environment
Tighten track hardware
using the Caterpillar torque-turn method for precise control
Perform daily inspections
checking for loose bolts, leaking seals and abnormal wear
Remove mud and debris
so that rollers are able to turn properly
Selection Factors
If repair is not an effective option for your undercarriage, ask these questions to help decide which Cat undercarriage is the right fit for your work and your machine. Precisely defining these parameters will help lead you to the best choice for your needs.

How to clean your undercarriage
For heavy equipment with tracks, getting dirty is a part of the job. But to protect the life of the undercarriage, regular cleaning and maintenance will go a long way to extended wear. Caterpillar recommends to power wash on a regular basis and always promptly remove any large rocks, mud or debris that get logged between the tracks. Many operators carry a shovel for just this purpose.
