I need some direction on how to change my fluid in my plow, and how to tell when it is full.

Also, where the fill and drain is. I am new to fisher plows, and plowing in general.

Thank you

Well, its a MM2, 9' on a 1997 Chevy 3500 dually, that is all i know, It supposedly came with the truck from the dealer if that helps.

being this close to a nasty storm, and not being familiar with it, i wouldn't touch it until after this storm is over as long as changing the fluid isn't a life or death situation for the plow. Is this your truck or a friends? MM2 is A LOT newer than 1997, so if you mean dealer as in when the truck was new, then you were lied to!!

Well, it has the plow attached to the frame, and the lights, i thought that was MM2, I might be wrong, all stickers are gone/painted over (by me) ... When I take the plow off the truck, the lights and frame come with it. I thought that was MM2.

The 4-5 times I used it this year I had no problems, so you are right, if its not broke, don't go fixing it a day before a storm :).. so how do I find out what model of plow I have? The reason I want to make sure it is full of fluid is because my lift piston leaks (VERY LITLE) it doesn't drop at all on its own, but a few drops do end up c oming out of the top ring.

the trianglular shaped piece that the top of the lift chain attaches to, is the top of it flat, or does it have somewhat of a rounding off to it? also, do you have to engage each pin seperatly or is there one lever to activate both pins simultaneously?

Do you connect/disconnect two or three wires when hooking/unhooking the plow?

that wouldn't matter, both the newest MM1's had the insta-act (three wire) as well as all the MM2s until this year. Also, the just previous of the insta act MM1s had two wire as well as this years models are back to the two wire setup.

How about posting a pic of the plow? Then we could tell you exactly what style of plow it is.

Yeah, but I'd put money on him having a MM1. If it's a two plug setup, then that's just reinforcing my theory.

a flat triangle piece, 2 separate pins to lock in, and 2 wireing harnesses to connect.

It must be a MM1,

So, how do I make sure its full of fluid? :)

When you drop the blade down and it goes into float mode, get out of the truck and push down on the triangular piece until you see the lift cylinder completely retract. Then, stand the plow up straight and open the fill plug. The fluid level should be just below the level of the fill plug on the side.

Would this be the same for a MM2? I have not changed my fluid yet and it is 3 years old. I know I am a bad boy. Is there a quick and dirty how to guide on how to change the fluid? Thanks.

Use this link to the Fisher Service Training Manual. Go to page 15, It will tell you what to do. We recomend the Fisher Blue Fluid in electric units. It the best fluid to use.
