Duetze Allis A/C

I seldom work on tractor A/C anymore but a good friend of mine asked if I could change compressors on two Duetze Allis tractors. A 9190 and a 9670. I know they a bit newer than most here but I thought I would try anyway. How hard is it to get at and change the metering devices in each to keep the warranty? I grew up Red and even then have not worked on anything newer than a 1586.The brief visual I had was they are in the cab and even though I have run both of them for hours did not pay attention to how the cab is built. Any advice is great and appreciated. I am also going to post in the Allis section. Thanks
Roger
 
Be careful what you get into on those, they were probably set up for R12.

What's wrong with the compressors? If they locked up, or the system has been open, it will need to be thoroughly flushed. If the old compressor shed metal it will be packed in the condenser. If it's a fin and tube condenser it will clean up, but if it's the vacuum brazed aluminum type they are best replaced.

Be sure to follow all the procedures as far as replacing the accumulator and getting the right oil and the proper charge. R134 is very sensitive to over charging.
 
On the 9670 the front seal is leaking. The 9190 the bearings locked up and stalled, There are electrical issues with that one also. It may take awhile to get them going I agree.
