    Anyone out there know if you could put a cocking or sometihng of that sort at the end of the shaft of the pistons to stop leaking ? I really dont want to blow 100 on each piston right now . Thanks guys

    I highly doubt that would work. There more like $45 for the angle cylinders I believe.

    Can't use caulking there :) As long as its holding pressure you can run it leaking if your short on cash. Just keep in mind you will need to add fluid, and moisture will also get in there, so if it gets really cold and your plow doesn't work, you may need to drain the fluid and get the ice out in the frigid weather a day before a storm. No big deal.

    Two complete cylinders for less than $100? I thought they were almost $100 each.

    To the OP - you can rebuild those. Your dealer should have the seal kit. The trick is getting the packing nut out. You should get the correct sized wrench. A pipe wrench can crush them. I would start soaking the packing nut threads with Fluid Film now.

    Depends on what he has, I'm thinking there the old style based on his Aviator pic. If so they can be had for $45.

    Ya there a $100 a piece. Its a MM1. I'm just tryn to take the easy way out for being cheep this yr. Plus i'm going to have to spend some money one the up and down piston as well cause that is leaking . Baught the plow used and i found out all these probs after i baught it. should of done a little more testing before i left the lot with it . The seal replacments for the angle pistons are $30 but the dealer told me good luck getting them loose and that i would be better off buying the pistons and others have told me the same . didnt know if you guys out there know differently.

    I dug out my old receipt from my overhaul last year. $90.86 at Donavon's for a PAIR of them 20117K. I think it was when Fisher dealers were selling parts at discount last fall / winter. Might want to give them a call if you decide to go new.

    Just slap new ones on. If the pistons are starting to rust, it will still lose fluid and collect moisture. IIRC I paid $80 each for new ones on my western ProPlow last year. Also, put new hoses on at the same time.

    You could try cleaning up the pistons with some scotchbrite or some cheesecloth and tightening up the packing nuts.

    my lift piston seems to have a ring of fluid on the top of the cylinder everytime it lifts up. seems to be a small leak, since it is holding preassure im just going to watch the fluid levels and leak.

    Try tightening the packing nut ....When you park it for the spring spray it(RAMS) with some F&F or lithium grease for the season....Avoids rust....It's called Maintenance.... Lube all pins TOO ......
