Need installation instruction guide for older fisher mm1 - PlowSite.com™

NWanner · #1 10-09-2011, 04:59 PM

The e-mail link on fisher's website bounced back and I couldn't find a phone number, so I'm guessing their customer service is non-existence? Anyways, I need the installation guide for a fisher mm1 7.5' plow onto a 1997 GMC K1500. I currently have an under hood hydraulic pump, but am working on picking up an electric pump.

I've used the fisher publications a few times very helpful in my opinion

I think I found the hydraulic pump installation instructions I was looking for, but it looks like a lot of parts and way more complicated than I was expegging. Would sourcing an electric over hydraulic pump save me a lot of troubles?

It might but it will hit you in the wallet pretty hard.

What is wrong with the pump? What pump do you have? The diagrams make it look worse than it is.

I'm not sure the exact pump I have, all I know is that it is a belt driven hydraulic pump. There was two listed on the fisher website, "GC belt driven.." and "belt driven.." and I'm not sure which one either. I was just reading that you have to remove and exhaust manifold bolt among a lot of other things and it made me uneasy.

Is there more involved in converting a belt-drive hydraulic to an electric/hydraulic than just hooking up the electric pump?

NWanner · #10 10-18-2011, 12:04 PM

Also, I'm missing the crankshaft pulley, belt, and it lists 100+ parts, mostly fasteners, which I don't have either.

sweetk30 · #11 10-18-2011, 04:43 PM

gc pump = gear clutch pump real fancy with electric clutch head like a a/c compressor and remote resivor.

belt drive = reg std old school unit.

and missing pulley on crank side. . .

sounds like a sehp factory fisher lift/angle pump up on the head gear or aftermarket unit is in order for you for easy of install and money.

Yes, it's a wholesale change. You won't be able to adapt much of the belt drive system to the electric hydraulic. Wiring harnesses, pump, isolation module, joystick, hoses etc. Well north of $1000 new.....sorry.

It's definitely an old school pump then. Could I get some details on those alternative pumps if you don't mind?

Good to know, thank you.

aftermarket unit all new ready to install. prob just swap your hoses from valve unit to this and fill up and blead out and go. http://www.northerntool.com/shop/tools/product_613_613

factory sehp pump would have to find used and possible reman. but when i see them go on ebay its basicly the cost of the aftermarket unit just about. but here ya go http://library.fisherplows.com/fishe...751_031203.pdf

if you have belt drive now then your wiring harnness is just for plow lights. so no need to change out. if aftermarket unit just add it and get good batt conections for trouble free use and go. also make sure you got good size alt for amps and upgrade the alt to battery cable to 4 ga wire for best voltage transfer. and the battery is high cca spec.

some guys might buy the old belt drive pump and control vale from ya so if you do swap then list them up here in the sale section and get some cash back.

Thank you for the info, I really appreciate it. Unfortunately it looks like an aftermarket unit (at least brand new) is out of the question as it would cost more than I bought this "complete" plow setup for. I guess I'll have to push forward with the belt driven pump. I saw mention of a shop in Rye NH with a good reputation so I'll give them a call and see what they can do for me.

sweetk30 · #16 10-19-2011, 03:56 PM

no problem on the info.

watch ebay for hydrolic pumps or plow pumps. try searching few diffrent ways. sometimes you can score a deal.

1 time few years ago i got a gc pump fisher unit the fancy clutch head and remote resivor pump and tank all new for under 300 shipped. thats almost 800-900 bucks new.

and if you find a 12volt pump thats only fluid power out and return you can reuse your control valve and plump the pump in just like the belt drivin pump and just hook it to a toggle switch and turn on when plowing and off when not plowing. as the valve unit will dist fluid were it needs to go.

you need 1500-1800 avg psi and 2.0-3.0 gpm flow to run the plow setup.

NWanner · #17 10-21-2011, 01:44 PM

Turns out that the 96-97 Vortec's use a different pump with a remote reservoir and I have the one with the pump/reservoir as one unit. For the $400 to get the right pump plus parts I'm think I might as well search out a complete used electric-over-hydraulic system and try to sell off this system to recoup my losses. Guess you really can't get into this game for cheap, either that or I'm just having **** luck with this.

sweetk30 · #18 10-21-2011, 06:59 PM

you got every thing basicly .

just grab a electric unit factory style or aftermarket.

the 96-up used newer vortec motors and was the last of the old style plows with live hydro. so finding specifc parts like we said will be super hard.

good luck tho and any more questions just ask.

NWanner · #19 10-21-2011, 07:16 PM

I'm going to see how much this local guy wants to fab a custom mount for the pump. If it's too much I'm just going to find a complete used mm1 electric/hydraulic, sell this complete setup, and be done with it.

Says he can't do anything for me and that my best bet would be to find the pump w/ external reservoir and bracket. Said that finding the pump wouldn't be the hard part, but finding the bracket for that pump to fit on my truck would be almost impossible as they only made them for a few months. All other options are more money than it's worth. I have a wanted ad up in the classifieds but I'm not very hopeful.

Plow prices are going up and they're disappearing fast too now. At this point it looks like finding an electric minute mount is the only practical thing. I have to sell of this setup and a giant bed mounted spreader first though before I can do anything else.
