1997 Monaco Dynasty with Cummins 8.3 A/C Compressor Motor

[jmcnamer]

My AC motor seized up in my coach.  I called Cummins and they could not tell me what compressor motor I had on my engine.  Would anyone know what replacement motor I need and the best place to get it?  The Cummins dealer said it "might" be a Sanden.

Any help is much appreciated.

Thanks,

Jody

There was a tag in mine.

I took a picture and NAPA got me a replacement. 

It cross referenced with one used on a peterbuilt truck from the same Era. 

It was the exact same pump.

I'll see if mine has one.  Do you remember where the tag was located on the pump?  I looked yesterday but could not find one.

Thanks again,

On the side about mid way.

I sprayed the housing good with WD 40

To find and read.

I ordered mine from AutoAirOnline.com.  I got the Seltec TM-15HS Compressor.  This was for my 1997 C8.3 Dynasty.  Here is the link to the page.  Same price I paid back in 2017 (except I had it overnighted at $100).

Thank you very much waterskier_1.  HUGE Help!.  Ordering it now.

Thanks for the help with the A/C compressor.  I evacuated all of the refrigerant from the system.  Changed the compressor, created a vacuum to refill the refrigerant, and it took 3 1/2 cans, around 30 oz of refrigerant.  Now the 12 oz cans are refilling the system, extraordinarily slow. (30 min for 6 oz)  I checked the high and low pressure and its holding pressure fine.  How much refrigerant will the system take, and how would you recommend charging it?

Thanks again for your help.
