"Lint" On My Pump Filter

    So this year I swapped over to a dedicated hydraulic fluid after reading posts here that it is perferred over ATF (which i had been running for years). And when I say I swapped, it wasn't just drain the ATF and put in the new fluid. I removed and cleaned out the internal pump and completely flushed out the angling pistons and hoses. i used a bit of kerosene to really get it all cleaned out.

    So now with 2 storms and 120 driveways under it's belt, I noticed the plow started to function extremely slowly. I checked the fluid and that was fine. So i removed the electric motor and the internal pump. Sure enough, the pump filter was blocked up with what looks like the lint that collects in the dryer. i cleaned it, put it all back together, and it works perfectly again.

    What is this lint-like substance??? can anything be done to prevent it from collecting? and why didn't i ever have this problem when running ATF in the past?

    the lint is from the lift and angling cylinder's,are your ram's pitted ? they scrape the cotton duct material off the packings .

    now that would make sense to me. there is no pitting on my angling pistons as they are about 3 years old and always greased when the plow is not in use. the lift piston is a different story. i got the pump used and it did have some pitting on it. i guess its time to invest in a new lift piston and packing set. thanks for the input wild bill. i appreciate it.
