    I need some serious help on an older western plow. My lift has decided to quit. this is an older mark II lift unit. it sounds as if the electric motor is fine but the pump will not lift the plow more than 1/2 an inch. I checked fluid and fluid was low so I filled it up and I am still having the same problem. If anyone can help let me know

    Try losing your packing nut on the lift ram. You will probably have to use some lube over a couple days to loosen it up. Good Luck.

    If the motor sounds strong then either the gear pump is weak or the inlet filter is plugged up...
    I'd pull the motor off and check/clean the filter.
    If you check it and it's clean, then the pump is probably weak..

    If the pump is week how would I go about fixing it?

    They're one of the easiest to change..
    If you review the manual you will see it's not a hard job at all..
    I posted a link to the Western service manual for these cable pumps in another thread here..(post #14) http://www.plowsite.com/showthread.php?t=51001

    B&B thanks it was the filter screen the bottom of the unit was gunked up with a thick sludge. Is there any thing else i should watch for should i replace fluid agian to make sure every thing is clean?. I just acuired this truck and I have been trying to fix all of these little quirks before I get out with it. The guy I bought the truck from said it had been setting for a number of years.

    Since it's a manual angle plow, if you cleaned out the reservoir real good when you had the motor off, you got 99% of the sludge/crud out of the system and you should be good to go...
    And congrats on a job well done!
