    Hello this is my first time so i hope i get this right. i have an old belt driven fisher pump i changed the pump three times in four years. so i want to change to an electric pump. i have an opportunity to buy what i think is a MM1 pump with piston attached its used with some cables. It came off a 8ft plow and my truck is 9 ft. first should i convert? if so how big of a deal is it? thank you for any help you can provide

    Well, you would need to change your controller, and add a new battery harness for starters. Not a big deal at all really.

    As far as the one your looking to buy, you'll need the 10" ram, not the 6", I would measure this right away, before considering it.

    I'm not too familiar with belt driven units, but there are several guys here that are. I'm sure one of them will pipe in shortly and give you a hand.

    If it were me, I would figure out what is ailing your current set up, chances are it's a simple fix.

    The manuals for both setups can still be had. The Belt Driven is referred to just that and the one your looking at is titled EHP.
     
  3. Three pumps in 4 years screams of something really wrong to me. It would be MUCH cheaper to fix what you have. Some things to check would be belt alignment, fluid level, and what if any leakage you may have. There also could be other things wrong that make you think its the pump.
    An old style belt driven pump should give you many years of service with proper annual fluid change and maintenance. Can you give us more info?

    BTW, Welcome to Plowsite!

    belt driven or MM1please help

    thanks to all who responded i truly do apprediate your impute. Ok so to answer all the questions. the plow has been on the truck for about 15 years at first it was working greatwhen i bought it then i had to Rev the motor to get the pump to move shortly after that the origanal pump died. replaced with a rebuilt ( scam) pump one year later it dird replace with a new fisher pump one year later it died. now the pump thats on their now is still working however when its cold it move fine but when its hot i have to rev the moter to get it to move also. also last year i played with one of the cables because the plow would not stay up by twisting the center cable i was able to adjust that problem is it possible its the cables? lastley i never flushed the fluid but i have to think most of the old fluid is gone after changing busted hoses and pumps. clearly i need more help. thank you again for any words of wisdom you may have to offer

    thank you for responding I just figured out how to respond to your message (lol) Ok I put in two fisher pumps they are new the last one is still in the truck however it's not working good. it raises slowly and when the motor gets hot it stops moving until I let it cool down. so I was thinking of converting to the MM1 pump piston set up. on the other hand if i can fix this unit. I would truly love that thank you for your help

    I would replace the fluid after each pump change. Your fluid is probably contaminated, and taking out the new pumps. I change fluid yearly even if nothing fails.

    What are you using for fluid? Is your belt slipping? Do you have enough fluid in the pump? Sorry.I know these are silly questions, just trying to get some info. 3 pumps in 4 yrs, something is killing your pumps. I have a 19 year old pump its alittle slow now, but going strong.

    Hello ok let me tell you I'm using dextron fluid in all cases but I never chaged my fluid so perhaps that's the problem? So I can buy a MM1 system today for 250.00 its used the question is is this a better f
    ix than the belt driven units

    I would go to the fisher website and look at exactly you need to make the MM1 system work on your truck. Is there any parts missing from what your buying that you will need to purchase. Will the MM1 Pump bolt up to your frame. You will need a new controller. Yes you will be upgrading, but you may have to upgrade other pieces to make it work properly. Wish I could tell you what to do, I would try fix what you have, but you have already done alot and sounds like your done screwing with it. At least flush your current system before you throw in the towel.
