Greeley Automotive Machine offers the most complete automotive machine shop services in Northern Colorado

Complete engine rebuilding: Let us handle your engine rebuild from tear down and cleaning to reassembly and painting. Let us rebuild your engine back to factory specs, and make it perform as good as, or better than new.

Diesel engine rebuilding: We can handle your diesel engine repairs. From small skid-loaders to over the road trucks, we can do whatever you need, valve jobs, crank grinding, block reconditioning, to complete rebuilds. Let us get your diesel back on the job!

Machining: From valve jobs, to cylinder re-boring, to complete machine work packages, if you like doing things yourself, let us handle all of the machining, on our state of the art equipment, and get your complete engine, or individual components ready for your reassembly. 

Balancing: Want your new engine to run smother and last longer? Buy a brand new stroker kit? Let us balance your rotating assembly, and feel the difference.

Dyno testing: Want to truly know how much horsepower your new engine has? Or better yet, want to know for sure that your engine will start and run just like it should before you lean over your freshly painted fenders to install it? Let us start, and break-in your engine on our dyno. Then when all is well we will do power pulls and see what your engine really makes!

Performance engine building: Bring us your rules, give us an idea of your budget, and let us build you a top-notch race engine. Circle track, Drags, Truck and Tractor pulling, or whatever else you race, count on our experience as racers to get you to, and more important, keep you on the track, and running fast!
