For this episode of the Rottler Featured Series, we head out to Tulsa, Oklahoma, home of Memorial Machine, where they’re setting a high bar in the remanufacture of the big natural gas and diesel engines that keep America’s oil fields running.

There we meet Rex Crumpton whose father founded Memorial Machine as an auto parts store and machine shop on Memorial Drive in Tulsa back in 1974. Today the company has two locations and nearly 80,000 sq ft of facility, making it one of the leading big engine reman facilities in the country with a reputation for service and quality that’s second to none.

As Rex will tell you, one of the secrets to Memorial Machine’s success is its focus on adopting state-of-the-art equipment and technology, which includes nearly two dozen of our most advanced machines.

From restoring Waukesha and CAT engine blocks to overhauling crankshafts, connecting rods and cylinder heads, Memorial Machine is leveraging Rottler technology throughout their operation to get the work done faster, more efficiently and accurately.

Walking along the banks of Rottler equipment in the Memorial Machine facility, Rex likes to point out that one of the advantages to the Rottler systems is that one machine can do many operations. And more importantly, once one of his staff is trained to operate one Rottler machine, they can run just about any Rottler machine – engine machining center, seat & guide machine, hone, you name it – which is a huge advantage.

Memorial Machine built its reputation on always delivering the best quality product, so it means something to us when they choose Rottler again and again.

Check out the video and, if you’re in the business of overhauling big, high speed, high horsepower nat gas and diesel engines, make sure to give them a shout!
