Extended Service Contracts (ESC)

A Power System Extended Service Contract (ESC) offers coverage beyond the Standard Warranty period and, because it is transferable, it may increase the resale value of your Cat® engine, marine vessel, or generator set. ESC offers protection against unexpected repair bills and a hedge against rising parts and labor costs by providing 100 percent parts and labor reimbursement for covered components, less any applicable deductible.

Engine Rebuilds and Swing Engines

Facilities: HOLT has a 6 rebuild shops with a new 72,000 square foot facility in Waco, bringing our total rebuild capacity to over 1,800 engines per year, with engine dynamometer capacacity up to 3600-8. 

A Cat engine is the best investment in value and productivity you can make, but when the equipment begins to tire, our rebuild programs can deliver a cost effective second life. Engine rebuild programs allow you to transform your equipment from tired to like-new, restoring its original productivity—programs unique to Cat equipment.

HOLT’s rebuild programs will meet your engine’s needs, whether it’s before or after failure,. The Cat certified rebuild program incorporates the very latest technology and critical engineering updates into your machine at a fraction of the cost of buying new. A HOLT CAT custom rebuild includes many of the same upgrades as a Cat certified rebuild but provides the flexibility to be customized to meet your specific needs.

Rebuilt engines are built to original emissions ratings and will include all critical engineering updates for longer life and improved fuel consumption. Replacement engines are dyno tested to help ensure same-as-new performance at a fraction of new price. Engines come fully assembled and ready to install, minimizing downtime and cost and are backed by solid warranty protection.

For fast turnaround, HOLT offers a swing engine program--exchange your engine for a rebuilt one, in the following:
