JDM a/c question

[jblueridge]

I'm going to buy myself an a/c charging manifold of good quality for my F150 and my BJ74.
Will I need plumbing adapters to connect to the BJ74 a/c system?
Thanks.

 

[SteveJackson]

Standard R12 fittings unless they've been changed by a previous owner.

 

[jblueridge]

Thanks. Will new, modern refrigerant couplings connect? Perhaps adapters are available?

 

[SteveJackson]

Newer style are for 134a fittings and do not interchange. But manifolds with adapters for various styles are available. For example:

[jblueridge]

So I could leave the compressor fittings alone and refill via fancy manifold?

 

[SteveJackson]

Yes, you don't want to change the fittings on the compressor manifold unless you are changing refrigerant type in the system.

What about changing the o-rings and seals. I have heard that they should be changes when changing types of refrigerant?

 

[SteveJackson]

Yes if changing refrigerant, you need to change the seals and the adapter fittings, you should also change the dryer to avoid contamination.

 

[jblueridge]

Yes. I have ordered these things.

 

[deepseacruiser]

Where did you get the seals and orings from

 

[jblueridge]

I ordered them from Rock Auto. I used the EPC to find a US vehicle cross-reference.
I believe it was the '86 FJ6X.
I can look for the order details.
There's always a chance the stuff won't fit.

 

[jblueridge]

Here's what I ordered.

 

[deepseacruiser]

Jblueridge, did you ever end up installing these o-rings and gaskets?

 

[jblueridge]

O-rings yes. Gaskets no.
That kit is a set of standard sized O-rings and worked fine.
The compressor I got was new and I had an a/c shop swap the clutch from the old 24V unit.

 

[deepseacruiser]

Thanks, did you end up just using the old gaskets or find elsewhere?

 

[jblueridge]

I did not re-use any gaskets. I flushed the system myself but the a/c guy did a final check. He may have done things I don't know about (although I paid him). All the connections I made involved O-rings.
