Technical Ac belt hitting lower radiator hose

I’m building a 48 F1 and the Flathead six went south, so I threw a sbc in it. I had a old Hurst adaptor motor plate to bolt it into the stock motor mounts. I ordered a vintage air unit for it. Started with bolting on the air compressor, and put the belt on. That’s when I ran into my problem. Anyone else had this problem and know a hose part number that will work?

 

Any way to shim that compressor up just-a-tad?!

IF not.....at least it gave you a bump-to-the-top!

I'd raise the compressor. It looks like the alternator sits much higher.

yup, you'll get beat up, because it probably won't work. The alternator belt has very little wrap on the water pump pulley, not enough to drive the compressor in addition to the water pump.

 

Is there an isolated picture of this compressor bracket on the internet?

 

Here is the bracket

 

I do like this idea, it would save a bunch of time. I’ll ask the vintage air tech tomorrow, but my uncle agrees with your solution.

 

Re visit the “plan”

 

I had to make a steel elbow for my truck, the exhaust bends available locally were not sharp enough bends. Paint it semi gloss black, and few people will notice.

 

I interpreted that to mean a 2 sheave WP pulley driving the AC pump?

 

I think that is what he is meaning!

 

hard too see how much clearance you need, can you slip the hose down the water pump inlet 1/2-3/4"

 

I'm thinking that the simple solution is to run an idler pully on the back side of the belt to bring it up and over and away from the belt. I'm thinking that it wouldn't be too hard to run a bracket off that black bracket that runs from the water pump to the AC now.

 

I have used stainless steel exhaust pipe and polished and shined it up so it does not look like some cheap afterthought that will rust out in a year or 2. Or corrode and plug up the heater core and radiator.

 

use large zip tie to flatten hose,,,ie drill 2 holes next to hose on either side lower cross member..zip to flatten that area..easy peasy

 

Have you talked to VA to see if they have a different bracket?

 

also keep in mind that the belt will flop around when it's under load, so you need plenty of clearance.

You might want to get a longer corrugated rubber flex hose, and see if you can route it down towards the middle of the car, then forward and up to the radiator. Or look for a longer molded hose that could be routed that way. You could notch the front of the mount cradle, to make a little extra room for the hose.

 

This engine was going in a Trans Am, the A/C belt was hitting the turbo charger. I made up a small idler pulley using a pulley off a VW timing belt tensioner. The water outlet on the timing cover was also relocated so the hose came forward instead of down, it all worked but was very tight. The idler pulley took all the " bounce " out of the belt.

 

The Alan grove higher mount compressor bracket might give you the clearance and more belt contact.

 

X2 @325w !

OP, see post #4 above.

 

Bingo. HRP

 

To me, an idler pulley is just one more possible failure point down the road.

Re-mount the compressor higher to eliminate the belt interference.

 

You can skin a cat six ways to Sunday with an idler!

 

You must have some good eyes. I don't see the alternator at all.

 

my 1937 ford coupe has the factory a/c. a vent on the cowl and a push-out windsheild!! I know, I can't spell wind shield right.

 

What I would do:

Cut the hose right where the belt crosses it:

Make the cut square with the hose.

Loosen the clamp on the water pump and rotate that cut section so the end points straight down.

Add in a mandrel bent elbow to couple the two sections of hose back together, t******* rubber and/or metal as necessary. Clamp-up and go crusin'!

 

Follow the other belt. It is not visible down low.

 

...nor is it visible up higher. Check the belts depth into the top of the water pump pulley. No indication of it getting shallower, indicating a higher mounted alternator.

It IS likely higher though, as so many were mounted that way, but there is no evidence of that visible in the photos. And maybe it isn't even an alternator.....

 

If you want to make a metal 90 deg part I made one from a 205 stainless pipe. Just need to get the right size pipe, mine was 2 different sizes. I would use a straight piece of rubber hose off the water pump and push the 90 back towards the block. BTW, I didn't weld it, I wanted it to actually work so I had a friend weld it.

Or mount the compressor up higher.

 

Perfect
