Heavy Duty Extended Life (HDXL) Undercarriage with DuraLink





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.




Maximize the life of your undercarriage


Undercarriage costs can account for up to 50% of your machine’s parts and service costs. That’s why it’s critical you take care of your dozer's undercarriage with proper maintenance. Watch this D11 walkaround video for best practices on what to look for to ensure you maximize undercarriage component life.

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 long will I own this machine?


How many hours a week will I use this machine?


What are my typical ground/soil conditions?


What are my impact conditions?


What attachments are on my dozer?


What grades/slopes are typical on my jobsites?





Dozer undercarriage is a big investment, so it pays to choose wisely. Turn to your local Cat dealer for money-saving advice on selection, operation, maintenance and repair.

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.
