    older model uni-mount motor works only when it wants too, clicking sound at the NEW solenoid, took the motor cap screws out and has rust all over the long bolts, cleaned the positive side terminal and the ground, my guess with the amount of rust that was on the bolts the motor has to rebuilt or replaced, would getting it rebuilt be cheaper or would it be better to get a new one,like i said it does work but only when it feels like it, I'm a rookie when it comes to plowing or working on these things so please be patient with me:help:

    You have a cable system? If you do, check the ground wire coming out of the controller.

    If you have a relay system, there is a black/orange wire (ground) connected to the solenoid....Make sure that wire is clean and making good contact. Also check the wire on the plow side to make sure it clean and making good contact..

    As for the motor, if your good at it,I would of taken the motor apart (you should take the pump off the housing to do this) , using a find sand paper, clean the top of the armature (copper around the shaft),clean the brushes, clean the inside of the housing, grease the brass bearing, then if everything look good, put it back together..

    Check all the ground wires making sure they are clean, and the positive wire as well, mount the motor back on the housing, and see if it works better compare to how it work before....

    Or just go out and buy a new if you don't feel comfortable doing all mention above..

    thanks Twinman, it is not the cable system type, i have a handheld electric controller, i would like to try to attempt that cleaning like you say but usually things don't go back together to well for me, there is a local company around here that rebuilds that stuff so i might have them look at it. Thanks again and Happy Holidays to everyone
    Thumbs Up just went outside and removed the motor, placed a large screwdriver into the base and attempted to manually turn the motor with no luck, hooked the battery charger directly to the motor and as soon as i hit the positive terminal on the side the charger just peaked liked it had a dead short, DAMN

    Replace the motor..Might not be worth repairing it..Most likely better off buying a new one, and maybe cheaper..

    As long you have the pump off the housing, it might be worth changing the fluid, cleaning the screen as well...I know I would if I haven't already done it.........

    Does this look like it?

    Pump #56133 single lug. ( not two lugs attach to the motor..Some come with a ground lug attach to the motor casing)

    Here is a web link..

    If you have a napa auto parts store, or a plow service place, they should carry the motor..There like $100.00.. Don't forget to change the gasket.. Also for the fluid, use the blue fluid..
