I would be terribly grateful if anyone might have a moment to help me with either of the following two inquiries. I have a hydraulic motor, possibly an old one, identified on the nameplate as Haldex Hydraulics Corp., Rockford, Ill. It has two numbers: 040206 and then further below: 77101. I would love to know its specs and especially the size and type of the fitting that should screw into the threaded holes on the sides. It’s too small for ½” NPT and too big for 3/8” NPT, and I’m not even sure it’s NPT.

Second, the motor is mounted on a blower that was removed from some kind of machine. I’ve attached a picture of the blower-motor combination. Do you have any idea what the application for this kind of blower might have been. You can see the motor on the right side and a 4 inch air intake on the opposite side.
I've been thinking of rigging it up on my Bobcat 610 to blow leaves and debris.

Waste of time. Derbis blowers are in the range of 8 in wide by 48 in dia. That thing is just not going to blow many leaves. You Probably have fittings that use an o ring at the base.
