Brand new, Cross hydraulic gear motor. Model 40MH10DACSC. Pressure balanced loading plates for high efficiency. Aluminum body for good heat dissipation. Pressure lubricated Teflon impregnated sleeve bearings. Internal check valves eliminate need for case drain at shaft seal pressures under 250 PSI.
Hello, I am looking to drive a leaf blower with this motor. My system has 3,000 psi and 8 or 16 GPM. My question is how do you deal with the condition when the hydraulics are turned off on the tractor and the impeller will want to spin down. I plan to be spinning the impeller at around 3200 rpm. Thank you
A: Item 9-8745 was designed for that specific issue. It features a relief valve for protect a non-reversing application's powered side; and a bypass check to allow for motor 'coasting' to a stop when a directional valve does not have work ports open to tank in neutral and there is a flywheeling mass attached to the motor shaft.

Could you give me the output HP for the cross series pumps up to 1.0 cu in if operated from a stated 18 hp pto on a john deere 1025 R . What Dynamic pump to use to get 2700 to 3200 RPM for each motor. I need the maximum output HP of the motor ( need 7 to 8 HP )
A: If item 9-8902-3 were used, you have just enough PTO power to push 7.4 gpm at 2500 psi. With that flow and pressure you would be able to see approximately 3400 rpm with 150 in/lbs torque from item 9-7073-50; generating a total of 8 Hp. You only have enough available power to drive one pump and motor combination.

Looking to possibly pair this motor with one of your White 1.1 cu in axial piston pumps, driven by a 24 hp engine. Do you see any problems with this arrangement that I am missing?
A: That combination seems to be within the continuous ranges for both products. There doesn't appear to be any obvious issues.

Thank you for the previous answer. Your mention about shearing the hydraulic motor shaft is a good point. The snow blower does have shear pins which are 1/4" bolts with grooves cut in them to reduce the diameter (i.e. give a wear spot). I would think that the shear pin would go before the 5/8" motor shaft, but... Is there another motor with similar specs that would have a larger shaft? Thank you.
A: Unfortunately, no. We don't appear to have anything in that displacement range or near that would work nearly as well. If there are shear bolts in the system it will help. It may be the best option at this point.

I have a mini skid steer that has 9.6gpm and 3000psi at the aux. hydraulic couplers. I have a 42 inch snow blower that I'd like to use with it that should be turning 1800rpms to work correctly. This seems like the right motor for it. Can I use this with a love joy to coupler to connect it to the snow blower shaft? Also, I don't know anything about case drains. How does that work?
A: Yes, given that set of conditions that will be about what you could expect to see from the motor. While it is possible to use a jaw coupler set to join the shafts keep in mind that at that speed and pressure you could see up to 10 HP going through a 5/8" shaft. If the snowblower jams for any reason with a direct coupling the motor shaft could shear before any relief valving could act. The shaft seal can tolerate up to 250 psi in the return line, so it's not typically critical that the case drain be hooked up on these motors unless you know the return line pressure could or will exceed that.
