Help! Is my motor Bad on E-47?

    I left my truck with a 'new' employee this weekend. I come back, works fine for 2 hours, then the plow lifts and angles very slowly and whines. I pull filters and clean them, check fluid level, and it is still just as slow and noisy.

    Pump was professionally rebuilt before the season started. What are the signs of a weak motor? I have one on order, but need to know that is going to fix my issue.

    I bench tested the motor after I pulled it off, it spins on the bench, but I am wandering if it maybe doesn't have the power to turn the pump. Pump moves freely when I turn it with my hand.

    note that it got worse quick, it is to the point now where you can here motor running and sounds noisy and plow wont move up left or right.

    More likely air locked than a bad motor.

    Pull all plugs again, re drain, disconnect hoses, refill, run up and down with chain unhooked. If it works fine then, then assume you have bad quick connects, swivels, hoses, or rams/loose packing nuts. You will need to find out which of the above, and bleed the rams out before connecting.

    If doing that shows no improvement, then replace motor.

    thanks for the reply. A few things to run by you.

    I hooked up a spare pump and it works fine, so that would mean the hoses are good.

    If there was a problem with a connector or swivel, I would assume that would cause one motion to fail, not Up, Left, and Right all at once.

    Let me know your thoughts.

    A bad fitting can let in air, and air lock the whole system.

    All I can say is that if the backup unit works, it's likely the motor...but I would go ahead and swap fluid completely and do what I said. on the off chance that the pump is air locked, you could save yourself some money. Worst case, you spend an extra $9 on fluid and still have to put a new motor on it.
