Frequently asked questions

Have a question? Refer to our FAQs for answers to your most common questions!

Don’t other market alternative undercarriage systems deliver the same life as Caterpillar’s product?

Cat’s quality and design drive system life. We offer unique products with extended life including SystemOne for many tractor models, deeper hardened links for D10/11, high abrasion undercarriage for D11, sleeve bearing track for D11, synthetic oil in components, post turn seals, positive pin retention, Chrome Nitride bushing end face coatings, consistent hardness depths and proper core hardness for component reusability. Dealers use Custom Track Service (CTS) to extend system life and support machine uptime and productivity.

How does the quality of Caterpillar undercarriage compare to other market alternatives?

Cat continually invests in methods to ensure and build quality into its manufacturing processes. Cat’s track sealability continues to be the best in the industry. We demonstrate our commitment to quality by providing Undercarriage Assurance to our customers.

Isn’t SystemOne™ just a product offering to attempt to lock the market place into continuing to buy Cat product?

The first and foremost goal of SystemOne is to provide our customers with differentiated product that provides the lowest owning and operating costs in the marketplace. At times, that means offering revolutionary product designs such as SystemOne which deliver unique benefits to customers.

Cat premiums are a stretch for the value received as compared to other market alternatives – how can I justify paying more?

Caterpillar’s cost per hour is less than other market alternatives even though the initial purchase price is higher. The cost per hour calculation is necessary is understanding overall product value. Cat’s components are reusable/rebuildable – bushings, track rollers and idlers. With the purchase of Cat parts comes the unmatched commitment and expert support from Caterpillar and its dealers. Undercarriage Assurance guarantees against leakage and breakage for an extended time period.

Isn’t Undercarriage Assurance comparable to what many competitors offer?

Cat Undercarriage Assurance is the best in the industry. The Cat dealer strives to inspect undercarriage at the end of the assurance period. Competitors frequently do not honor their stated coverage to the customer.
