I wan to add live hydraulics to my 49 M and would like to try and use the fan belt. More specifically the belt that runs the altenator. My question is had anyone done this and can you keep enough tension on the belt to keep it from slipping? If this will not work what is the next best option? What size pump (gpm) would I need to put on the say lift an after market 3 point, power steering, etc.

Thanks,
Bob

Go to your local wreckers and look for something that has a multiple v-belt drive on the harmonic balancer. All you have to do then is match crank sizes,. This will then give you a dedicated V-belt drive for your hydraulic pump. Best of luck. Alex

I believe Northern Hydraulics had a blet driven pump with an electric clutch on it. Not very cheap though :)

I've seen some (little Ford/Ferg??) that have a shaft that goes through the "hand crank" hole in the nose and mounts on the front and would be direct drive to some type of coupler on the crank pulley. You'd have to watch direction of rotation and take care not to bump anything with it sticking out the front. I'd look for one from a 400-450 as mentioned above if it was me and my $... good luck

Quite a lot of Combines (e.g. Claas Matador) had a hydraulic pump driven by a vee belt.

M&W made one that bolted in between the distributor and the cam gear. I have seen Case live pumps bolted in there also. You could also get a pump off of a 300,350, 400,450.

I would add a pulley to the crank & dedicate a belt to just the hyd pump. Sharing a belt means at least 3 pulleys for the one belt, and then they don't circle any of the pulleys enough & slip much worse.

Sharing power steering & anything else makes for erratic operation. The power steering is usually the lowest demand, so any time you turn the steering wheel the rest of the hyds stop operating. You can plumb options (more $$$) to make this less noticeable, and a lot of us have tractors that share steering & lift - sure beats not having either. :) Just a heads up if you hadn't considered it.

By the time you put all the parts together & modify sheet metal or brackets to make it work, would a distributor pump be a little neater & about the same money, or do you need more gallons?

I had thought of adding a pulley to the crank, but was looking at the ease of putting the hydraulics on. How does one go about putting a pully on the crank and what type of pulley. What is the price on a distributor pump, I've seen them but don't know much about them.

I have an industrial I-6 which is a w-6 and it has a pump mounted via belt from the crank pulley. It is used to lift a large blade. It resembles a pto pump you might find on a truck. I can take a picture or two and send you if you would like to see it. The belt that drives it is of good size, perhaps first finding a pump suitable for your demand would be better then finding a pulley to match the speed and pull.
