Pump motor question

    Hi Guys,

    first off, I'm a newbie so excuse me if this is a stupid question.

    I just had my batteries checked and replaced in my truck. I have an 03 chev diesel with dual 850 batteries (new). The alt was check and is good. I picked up a used 7.6 western pro-plow last year and it worked great. This season I haven't been so lucky. The plow motor is drawing alot of power and will work for about two minutes and then nothing. When it is working it is slow. I had a bad connection on my nine pin connector and I have replaced this with new connectors, I replaced the solenoid because it there was a small bit of corrosion and rust on the posts. I disconnected the chain from the blade and the lift ram didn't work, I gave the motor a little bang and the lift ram worked (with the blade disconnected) but not enough power to raise the blade. Just wondering if it is a new motor that I should be narrowing in on?

    Also, if it is the motor, is it difficult to replace. Looks to me like it's just removing the pos and neg cables and two mounting bolts, and replacing the cork gasket. Any advise in doing this?

    It seems like you are having a problem with the motor. If you had your electrical system(charging, batteries) and no problems found, I would say check the grounds before making a decision to replace the motor. Like I said before, it seem most likely the motor should be replace.....

    Thanks twinman326. I checked the all grounds last night after replacing solenoid, also replaced any wiring that looked shotty. I checked NAPA here and they don't sell plow motors, so it looks like I'll have to head to the dealer for a new motor. Thanks for your help.

    worn out

    pull your motor,2 bolts and cables. the motor is easy to take apart but if your not comfortable with this just replace it. chances are your brushes are worn out, depending on how much plowing you do brushes generaly only last a few years. i always have spare sets but plow almost 6 months of the year, nov. through april. the commutator on the armature also gets dirty and needs to be buffed up. many motors get purchased but a good part of the time they can be put back in service with just a little tlc. it could have shorted windings also but rare . a clamp on ammeter can diagnose a bad motor in seconds. its your call on how you want to look at this but i am a mechanic and repairing is always my first option over remove & replace. there is a few other checks here but almost guaranteed it is your motor

    Hi Guys, Thanks for your comments. As for hauling the motor apart, I'm OK with. I figure I got nothing to lose.

    Yup. I figured the time I would spend fooling around with the old motor wasn't worth it. I picked up a new motor at the western dealer for $160 (and warranty). It went on in a snap. I changed the gasket, fluid and checked the filter (which was clean). I cleaned up my in-law's driveway as a test of the blade and also to keep in good standing for those Sunday Turkey dinners. The action on the blade is alot faster. Now we are expecting rain on Thursday, so I'm a little ticked off. I need some white fluffy stuff.

    I checked the link you sent but the motor from Angelo's would have cost more by the time I added the exchange, shipping, customs/duty and brokerage fees. Thanks for the link though as it might come in handy in the future. In the meantime, I am going to keep the old motor and haul it appart in when I can get around to it. If I get it working then I'll have a spare. Seems like you can learn alot from other members on this forum. Thanks again.

    Glad it work out for you.....Just to let you know, there was no exchange on the motor....That was for the whole pump unit..I buy a lot from there. reasonable price...Another place that is decent, equipment specialists inc.com They have a break down of all the parts.. It was snowing here last night, but not enough to plow snow.........Happy holidays.........

    Thanks twinman326. Yup, they have good prices alright but the the exchange I was referring to was the currency exchange (USD to CAD). The prices on that website were excellent,especially for the full pump unit, but would probably double by the time I got it to my door. The pump alone here is about $400 at the dealer.

    Have a great Christmas and have fun in plowing. It's freaking raining here today and more rain tomorrow. Looks like it might be a green Christmas if this keeps up. Just my luck, it snows when the plow is out of commission and then rain the day after it's in working order again!! I should change my username to "Badluck Schleprock" from the Flinstones.

    changing the name won't help for a snow storm...I didn't realize about the exchange...U don't have something like Angelo's in your area? Probably if you did a web search for your (Cad) area only you might get lucky........

    Yes, I'll have to check into it. The western dealer here in town is a locally owned family business who have great service. You can contact them at anytime and they'll help you out of a jam. Their prices are generally pretty good as well. But it's nice to have another option if the prices are significantly different, like $90 for a genuine western motor and pump unit. As for the weather, I'll have to learn the snow dance.

    Does anyone know if the motors angelo's sells are the OEM motors (for an insta-act/ultramount pump unit)?

    They're aftermarket. Easy way to know is by price. Anything approx $100 or less will be an aftermarket. Genuine motors start around $150 and go up from there.
