    Default Hyd motor ID

    I have a rexroth hyd motor I need some more info on. There are 3 numbers on the tag attached to this motor.
    codice#7.003210001
    serial# 1301569 028
    data# w2311

    Info I need is cuin displacment, max flow, max psi, and max rpms.
    I know this motor will run 3150rpms at 2150psi and 18.5gpm. This suggests a 1.3cuin motor. I have been told, but havent be able to verify, that this motor would run at 4800rpms at around 30gpm which are the numbers I am shooting for. I just hate to go thru the build process and findout my info is wrong at the end of the project. Any help would be appreciated.

    30 GPM would run the 1.3 cu in motor at 5331 rpm.

    Where did you get the pressure limit from?

    Check your motor out with some comparative data.

    Bosch Rexroth Mobile Hydraulics

    PSI BAR Converter

    Cubic Centimeters To Cubic Inches (cm3 to in3)

    That is not a lot of torque.

    What are you building?

    JJ, this motor is used on a vibrating assembly. The numbers posted came from the schmatics for the equipment. I am wanting to use the motor to run a hydraulic chainsaw. I dont believe the numbers I posted are the lmits for this motor, just what it is speced for the particular assembly it came off of. I am trying to find out what those limits really are.

    These do not look like any Rexroth part numbers that I have ever seen. Suspect these are the OEM numbers from the machine you took this motor off of.

    I presume this is a gear motor with that small of displacement.

    I am suspect as to displacment. This motor is a bmount and weighs probably 25lbs, with #12jic ports and a casedrain. The numbers came off a tag attached to motor. It is, or should be, a rexroth, but it is a special application motor. I havent been able to find anything using those numbers either. I suspect the equipment manufacturer could have attached their own tag to the motor, but those folks wont tell me anything about the motor. Sell me a new one they will, but I guess they are afraid someone might try to find a cheaper replacement instead of buying one from them if they give out to much information.

    Can you post a picture of the motor. Some times a picture is worth 100 posts. This may be one of the older Rexroth gear motors that they sold to some one. I want to say Haldex Barnes but not sure. I think they were made in either North or South Carolina. Just looking in one of my old books and the 1.28 cubic inch that had an SAE B mount & had #12 SAE ports. Those models all stated with PF in the model code and were good to 3600 PSI.

    That looks like an axial piston motor. Possibly A10F* series. If you remove the SAE plug show in the top middle of the motor do you see a rotating group consisting of the cylinder and some pistons. If you remove the work port plugs you should see some kidney shaped ports that feed the pistons.
    Do a google search for RA 91172. This should be the data sheet for the A10FM motors.

    I think you are on to something, the a10fm 23-28 looks pretty close to what I have. I still havent figured out how to match the numbers up to cuin displacment

    looking at the serial number serial# 1301569 028, and assuming the last 3 numbers also represent the displacment, then this would make this a 1.73cuin motor. My 30gpm intended fluid flow would produce only 4006 rpms. My intended pressure was only 1500psi and would yield 413inlbs and about 31hp. Not exactly what I am looking for.Do these numbers sound about right to you
