    When you changed the fluid did you find any water in the old fluid? How did you determine that it froze up? Just curious.

    well i got more info from customer at work. he said it wouldnt lift . but the chain took up the slack and that was it. he drove it 2 miles with it down. then just before he got to the shop it poped / banged / what ever and lifted up.

    i played with it out in the lots and it never skiped a beat ever. and i ran all options on the blade. i even checked for green in the electrical plugs. none in there just lots of electric goop like thay are supost to have.

    so i told him it might have been a rock in the piviot point or some fluke thing like a slight bad cirket contact at the plug. drive it till it does it again or i cant fix it. you know the old thretin it with the fix it man and now it aint broke rutine. :dizzy:

    Since it would pull the slack out of the chain, then the valves had to be working in order to direct the fluid to the lift ram.Sound's like it just didn't have enough hydraulic force to lift the plow.Probably due to a "stuck" pump relief valve. All it take's is a tiny piece of debris to hold the relief ball off it's seat, basically causing a hydraulic leak on the pressure side of the pump. The Western's need at least 1100psi of pressure just to lift the blade off the ground.
