Two Pittman spur gear motors. These are "new old" motors, with 1986 date codes. However due to Pittman's extreme overengineering, they still sound and run great. Has solid steel internal gearing. External shaft is short, about 1/4", with a stainless steel 12 or 10 pitch spur gear that can be attached to additional gearing of your choice or pulled off with a screwdriver.
These can make good 4WD motors for a medium-sized robot if wheels with gears on them are mounted next to the motors.
Pittman #GM9432E962
24v nominal, 3.25A stall, 11.5:1 reduction. Gearbox is 2" diameter at the widest point
Specs derived from Pittman datasheets:
307RPM/v, 4.4oz-in/amp, motor only. This works out to be around 650 RPM no load with the gearbox and 164 oz-in of torque at stall.
Mount using two simple threaded holes in the face of the gearbox.
Motors have only been run for testing and never used. There is surface weathering from sitting around for so long, but this does not affect motor operation at all
P.S. Sorry I didn't answer your question about the pictures of the #2060 chain problem, my computer had i virus and didn't want to risk infecting anyone or anything. Will get pictures A.S.A.P
