AC suction line help.

[86 1/2 Brutus]

Ok ya'll everything's in and is holding a good storng vacuum.  Here's the problem.  Four seasons strikes again, the suction hose is WRONG  it cant fit into place without kinking and the end does not fit correctly into the compressoer.  We took the old suction hose and used it and is holding a vacuum.  Here's the thing.  we forgot to flush it.  How screwed are we??  Help

As long as the old compressor dident explode or sieze up, or anything like that, you should be ok.

[86 1/2 Brutus]

It was the hose from the condenser to the compresser that busted years ago.   the compresser didnt blow up or seize, we just decided to replace it.

[old55pete]

You should be good if the hose does not leak under pressure.

My next question is kinda out there, how are you going to fill and test pressures without the radiator in it? The only way to do that is with the engine running.

Just a thought.

[86 1/2 Brutus]

we wanted to hurry up and pull a vacuum on it because everything was open.  we headed to autozone right now to get a belt and some new antifreeze.  we will be putting it back together before we try to fill it

[old55pete]

Is this the hose you need?

[old55pete]

Got it, I will shut up now.

[old55pete]

Ok, I guess I wont shut up, but just for a second. I see in the picture that the anti-vibration bracket is missing. The bracket goes from the back of the compressor up to where the hoses come together above the rear of the compressor. It may sound stupid, that bracket stops the vibration and keeps the aluiminum from braking.

Just a thought

Good eye Steve!

I think it was Matthew (Maybe Dave?) Who said that bracket vibrated off their compressor and it was making a racket.

But any kind of stay is better than no stay.

If you look it up in the HVAC in documentation, it shows a picture of it for the 460's in the ac brackets if you need to know what it looks like.

[86 1/2 Brutus]

OK, here is where we are at right now.  The four seasons suction hose is correct.   The system was not holding a vacuum with the old hose.   I remembered something.  who knows how long ago, we got a coplete ac system out of an 84 bullnose.   I was sitting in the old truck seat and something, i think maybe God made me get up, go to the trunk of the wrecked vic and open it, and there it is sitting there in front of me.  Brutus's original compressor with a manual shut off valve at compresser.   We swapped everything out and the vacuum pump is no longer pulling in air.  Wish us luck.  Going back out there.  My aching Back

Good luck with that, George!  

You really need a ride with good AC in your climate.

[86 1/2 Brutus]

Ok, it's stillholding at 30 psi, we are going to charge it tomorrow.  Only thing that concerns me is the compresser.  first off, the pulley is bent on the outside edge, i didnt notice that,the part where the belt goes seams to be ok.     When i bolted the blocks to the compresser, the bolts stripped and i did not apply any torque at all and they just stripped.  i pulled some more out of other compressers, same thing.  I did manage to get 3 in, good and tight and have to use a washer on the 4th one.  I'm thinking slightly shorter screws

Oh yea, the AC in the house went out

[86 1/2 Brutus]

Steve, we have the bracket.   Please dont shut up.  Good eye and thank you

[86 1/2 Brutus]

Good thing we save everything, because you just never know when a junk compressor just may come in handy, and they say hording is bad.

[86 1/2 Brutus]

Just went check on Brutus, He's still holding at 30 psi.  Hopefully will be able to charge it today

[Gary Lewis]

If it held all night you should be good to go.  Hope it works out.  

[86 1/2 Brutus]

Yea it's still holding on 30psi.    Hopefully the house AC only needs a run cap.  It's hot

The only thing I had fall off was 1 of the brackets that go between the main block bracket and the compressor and made 2 new ones from alum. plate.

I don't have / never had that hose bracket, if I ever come across one I will snag it.

Good to hear you are getting the AC system running.
Them hoses can drive you nuts.

Now that i got everything set up, I did a search for the manual shut off valve, of course nothing comes up, but i did find the suction hose that seams impossible to find.  I found the one with no shut off valve at compressor.  Look up a 86 with a 351w, it will give it to you.     I'm going to start a new thread once this is all said and done with all the correct part numbers and everything
