I am from the way back but, the machine for me is the H/S50XL Hyster with a "C" prefix in the serial number. They repaired all of the flaws between the "A" and "B" models and hit a home run with the "C". They were available with the Isuzu (diesel), Mazda or GM power plants (the Mazda being more durable with less problems). The transmission was simple, the cast steer axle was heavy duty and the drive axle was bulletproof. The unit was not without flaws though. #1 The engine harness main connector would fail yearly and need replacement, #2 The tilt cylinder shells would crack at the rear weld #3 The Transmission control valve leaked (repaired by doubling gasket) and #4 The upright tilt bushings would only last about 3000 hours. All around a great machine. In my opinion, a far cry from the over engineered units we have today. Sometimes more is not really better.
