Truck Service


The durability of Cat Truck Engines is legendary. Many are still in operation after thirty years on the road—and our service staff has the training to service them. In fact, our technicians are the most experienced and best trained in the Midwest, and they’re on call 24 hours, seven days a week.


Altorfer is authorized to perform warranty repairs on Cat on–highway engines in all kinds of vehicles, from semis to fire trucks to RVs. And with Caterpillar’s World Parts Distribution Headquarters and On-Highway Engine Manufacturing facilities located in the middle of our territory, we’re better prepared than anyone to meet your most urgent service needs.


Altorfer offers guaranteed low cost engine overhauls on all makes of Caterpillar powered trucks. Altorfer uses genuine Caterpillar parts overhaul kits. Service history is checked to insure your engine has all the latest factory updates. Based on the life of your engine and your buying needs, we offer Bronze, Silver, Gold, and Platinum OPT overhauls. Please check out the best, before trying the rest!
