Really like the looks of your hydraulic pump set-up. Planning something like that for my M. What brand or make is your pump? Thanks--Bert

The pump is a Borg-Warner. It is at least 20 years old. I am told that B-W no longer makes them. Northern Hydraulics has an identical pump in three different displacements. They go for around $520.

I previously used the pump in my '86 Ford F-350 Diesel. Many other trucks were set up like that. A salvage yard that specializes in trucks should have a few. You could also try any truck equipment dealer to see what they have.

You will go nuts installing it if you use a 7" driving pulley on the crankshaft. The V-belts just clear the frame channel by 1/8". But that may only be a problem because of the front Fast Hitch I made. The bottom of the fan shroud also has about 1/8" clearance from the pulley. The next size pulley down is 6". I am glad I stuck it out with the larger pulley. What you use will depend on the displacement of the pump and your hydraulic power requirements in PSI and GPM. Have fun. I'll send more pictures if you need them.

After I wrote the above post, I remembered that my nearby auto repair shop has a used clutch pump similar to mine sitting on a shelf. I can find out if he wants to sell it and get a price.

Thank you for the information and especially the pictures. I will have to modify my tractor somewhat. The aftermarket front end mounting prevents me from placing the unit below the frame rail. May be able to work something out on the left side near the governor. Again, thank you

Thank you, but I think I have one on an old Ford PU that I have.--------------Bert

If mounted near the governor, you will have problems using a 7" pulley on the crankshaft, maybe even a 6" pulley would be too large. I think all the electric clutches for those pumps are 7". I think the V-belts will have clearance problems with the fan shroud if the pump is mounted higher than the crankshaft. Of course, you could cut the shroud.

Perhaps you could install an air conditioner clutch on the hydraulic pump shaft. I dunno. One has to consider if that will provide enough "grab" if the hydraulic circuit is demanding high PSI's.

I'll have to take a look at my 400 to see if something could be worked out.

I took a look at my 400.

I don't see how you can run a clutch pump like mine above the frame channel. The add-on crankshaft pulley would have to be very small. Probably in the range of 3". That means the pump will only have a maximum RPM of something like 700 RPM. That doesn't give you alot of GPM .

Those that run pumps above the frame seem to be using regular pumps and do it in two ways. The first is with sprockets. The second is using the IH fan belt in a triangular fashion that runs over the crankshaft pulley, water pump pulley, and the hydraulic pump. You are not going to find a clutch pump with that kind of pulley.

One other option is pictured below. This might be a M&W attachment or perhaps Behlen. On this tractor the fan only has 1/16th" clearance before it hits the pump pulley. The fan shroud has been modified. IH had a similar set-up for tractors not equipped with a Hydra-Touch or Lift-All system. I doubt if they chopped up the fan shroud however.

If you want to use a clutch pump, you should think about modifying the aftermarket front end bolster or swap what you have for a genuine IH wide front end as used on my 400. Or go trike.
