If you have a lathe, a bridgeport and a mcmasterr carr account, you can do just about anything. I wasn’t fond of the three legged “spider drive” attachment that was included with the transmission dyno - it lacked precision in the concentricity and runout department. Necessity is the momma of invention - I machined a Cummins crankshaft simulator. This way I can bolt up any flexplate that is used behind a Cummins engine and have a drive that runs seamlessly.

TIG is one of our credentials. It makes the
TRANSMISSION

GREATER
If your builder can’t TIG weld your 68 pinions and ring gear orifices, you may want to go somewhere that can.

Why do I weld every one?
Because 48 thrust washers need all of the oil they can get!
