I had a question for that particular compressor.


Is it built to withstand r134-a refrigerant!?

Not a fan of Standard Motor Products Remans with any refrigerant.

In answer to your question, yes, the original process of re manufacturing this unit was made to function with 134a. The only short side was the pistons utilized, however, rumors abound that this has been changed also.
The issue that is most disturbing is the movement of the production to Mexico. Not sure if this affects quality, but when another re manufacturer did this several years ago...it was disastrous.
Check with your Murray jobber (if that is your choice for purchase) to determine the cost difference between this and a new unit.
The other option is, of course, this site that offers a new unit.
The largest downside to retro fitting a system is properly charging the system. Failure to complete this most important task is total failure of the compressor due to lack of lubricant migration. This is the #1 cause of compressor failures.

Come on Ice still holding on to the party line after all these years! New OK not an issue. Reman by SMP have been nothing but trouble but maybe they have improved since the last time I used one.

I just put a brand new Delphi R4 into my '94 Suburban a few months ago. Granted, the R4 is well known for issues anyway, but what I've read is that the cost to rebuild them correctly is more than a brand-new one. So rebuilts are suspect for R4.

AMA can supply a brand-new R4 for you.
