Standard PTO mounting measurement between mounting holes - sides 2.75" on CL and top to bottom 5.50" on CL. It turns freely and shifts by hand. This is dirty and needs a good check over, I see one issue , it looks like someone torched off a yoke and accidentally cut into output shaft, see pics. The cut doesn't appear to go past the sealing area but shaft may need to be replaced or reconditioned. No missing teeth on gears.Might need bearings and seals. I think it can be used as air shift with air solenoid (not included) but not certain, item is exact one you will receive.
Im sorry I do not know what this would fit. I don't know what it came off of.
Most certainly an older semi truck or tractor. Possible applications are Kenworth 397 Peterbilt Volvo / White GMC Drill Rig Rail car service Mack Tri-axle dump truck owners and over the road truckers.
