    Hey there,

    I've been thoroughly digging for answers to this, but couldn't find any. I have a 1993 F250 with a similarly aged Unimount Western setup. It's been giving me issues since I've had it. Basically, it takes about 7 seconds to raise the blade from the ground to all the way up. This is WAY slower than my other truck's unimount with a new pump. However the left to right is fast as new. When it's warmer out, the plow seems to rise a tad faster, but it still isn't where I'd like it. I was toying with the little valve (screws in and out to speed up/slow down plow drop speed) and for some reason when I screwed it in tighter, it dropped quicker, although I read the opposite. The truck also has a brand-new battery, and fresh fluid. It took 3/4 of a quart, so it could have been low before.

    Basically, I was wondering if it could be the motor (although it's clearly making noise and raising the plow) or the pump. Should I replace the pump?

    Get a 5000lb gauge and do a pressure test. You can take the motor off and take the top off, give it a look. You did clean the filter.
