Brings back memories, I was a Service Rep for Clark back in the 70's/80's when coal was blowing and going. 475C was 12yard machine, we also built several 675's, 24 yards, twin 1710 Cummins engines.

I remember those, the transmission was made by Voith. Worked good but sometimes operators took a long time to get used to it. Those torque converters were only 10" and ran at twice engine speed.

I made a trip to Climax Co. once to do some mods on 475's Climax Moly is what I think the name of the place was. I think we were testing hydraulics for overheating. Dead of winter, hard to get them warmm never mind overheating.

I can't remember the reps name right off hand, young guy, a little goofy but smart, really good on engines. Gale Stokes and I worked together at different times. I spent a couple of years in the Lab at Benton Harbor. I know Gale was in the lab once and a 475 wheel and tire fell on him, any smaller man would have died. I worked a lot of 380 Coal Dozers at Georgia Power, they had about 25 or 30 of them. I kept all my service books, I'll try to look the reps name up.
