Need your help

[gardener]

Hello friends, I'll need your help, I am looking for a good company who can make me a double grove pulley, it can be the crankshaft pulley or the water pulley, this pulley will be used for moving the air conditioning compressor on my 69 Spitfire. Or if someone knows if the late 70s have the same pulleys and it has double grove pulley. It can be made in aluminum.

this is the original pulley

and this is a drawing of +- what I need

I am not sure I would run it off the water pump pulley. I would think a belt off the crank pulley would be better just because adding to the water pump will put more pressure on the bearings inside the water pump I would think. I may be all wrong but that is my guess.

Thanks Tom, it can be off the crank, but I still need if someone knows who can build this crank pulley out of aluminum, like the one used in the hot rods, and if I'll use a crank pulley now for 2 uses w/p and a/c compressor, is better to: smaller diameter pulley, same pulley or bigger pulley.

A good CNC machine shop can easily do this for you, but it won't be cheap.

I check the price of the A/C system over the internet they're around $900.00 to $1,500 , I went to a big A/C supplier here and found a complete system for around $500.00 so I still have a gap of what I figure it will cost me, and for this constantly hot whether ?? $$ remember my first language is spanish I am not to good with the english abbreviations "CNC machine shop" ?

I believe CNC stands for this. Computer Numerical Control



If you go to this site at the bottom you will find more detail about it.

Just a little free advise, run your A/C off the crank pulley with an idler pulley for belt tension, it will save your water pump. Many early Ford cars and trucks use an A/C idler and should be easy to mount. Ford in the 60s and 70s use a small multi grove crank pulley. Good Luck. Bill C. Mesa, Az.

In the late 60's, early 70's it was fairly common to add A/Cs to Herald's here. I saw (and almost bought) one a few years ago. As I recall, they just used one long belt for everything. The compressor was mounted on the right side of the engine below the water pump.

maybe this is a better idea, I'll try this one if the results went fine I'll tell!!
