im wondering if anyone has had success in adding another pulley wheel up front for an additional belt driven accessory? Im thinking of a pump specifically.

 

I added a separate V-BELT pulley system that drives my Ford A/C and the belt-driven vacuum pumps for the trailer brakes.

I was fortunate to have a brand-new shiny zinc-plated B pulley that was exactly the right diameter for the job; this pulley was in a big box-lot that I had bought at an auction years before for probably a couple dollars.

I had my machinist/genius re-cut the center and lathe-mark/drill the six holes, such that this B V-belt pulley is immediately in front of the fan pulley.

I very much prefer my auxilliary V-belt system over adding more serpentine pulleys and a longer EXPENSIVE belt.

It is a simple matter to eliminate any offending unit that is V-belt driven; not so when one long belt does it all.


I doubt there is room between the fan blades to do likewise with a secondary serpentine-belt system; maybe a 4-rib, but not an 8-rib.

 

yeah i was thinking a v belt would be best for sure. just wondering how would be best to mount it and to what? would the alternator position be a good choice? and what was your method of disengaging it?

 

anyone else have any experience with doing this?

 

I know there is a v belt pulley that can be added to the alt but I forget who makes it.

 

What pump are you trying to run and why would you want to disengage it? Mine has a hyd. pump mounted high on the driver side with a a/c type elec. clutch.

 

im thinking about mounting a haldex hyrdaulic pump for the purpose of pumping veggie oil through a centrifuge. engage/disengage for while filtering or not.

 

I am a little confused by the question.

My V-belt drive pulley is direct-bolted onto the same bolts that hold the fan pulley.

My only means of dis-engagement is to remove the V-belt.


Another probably easier option = I often see alternator pulleys on E-Bay and the like that have both the 8-rib plus a V-rib groove.

Be aware that there are several sizes of V-rib groove.

Cars and smaller engines are usually equipped with "A" size belts.

Most diesels and equipment have "B", which are larger at 5/8" wide.

I much prefer the "B" size.


You can get away with using an "A" belt on a "B" pulley, but not the other way around.

 

anyone else mounted pulleys off the fan pulley? do u have any photos? or how ya do it? do u have to take off the fan and fan belt pulley?

 

ive got a zena welding system, ive got their accessory pulley mounted to the alternator, adapting the welder drive with a short-v belt, I adapted the alternator bracket to mount the welder on top when needed, at above idle rpm, I get 150 amps of power, the welder also doubles as a backup alternator. the fan clearance to the fan pulley dosent warrant much room for anything, without deleting the fan, so I went outboard.

 

Another vote for a v-belt combo pulley on the alternator. I have mine driving a compressor for on board air.

 

I have a hydraulic pump mounted on the drivers side and a v belt running off of the fan. I had to get rid of the fan clutch to mount the kit that I have. The hydraulic pump has a clutch like an air conditioner. I tried getting rid of the engine fan and using an electric unit, but had trouble with the truck heating in the summer while towing. I also had to remove the oil filler and install a filler in one of the valve covers.
