I started doing some plowin and was getting tractors serviced and makin sure every thing worked that old blue tractor of mine wont blow cold air,R12 leaked out over the winter,and since R12 is damn near unobtainible Im thinkin bout changing it to R134 ? any advice would be appreciated as to how to proceed,I know the government likes to se the old refrigerant reclaimed but I dont think there is any left,so was thinkin about the new R134,never have done this and I sure dont want to burn up the compressor,I know you need to put oil back in them and I think that is where you gotta be careful,as the oils dont mix ?
I only need the a/c workin when Im round balin,damn hard to stay in a cab without a/c when the temps are 100+
thanks & good luck

I had our 1994 model 8630 Agco Allis converted to the R134, but it never worked right, so it was put back to the original R12. Now it works like a charm again. My advice is to just find some of the original refrigerant. Please get other opinions, because my mechanical knowledge is next to none. :wink:
 
Our local mechanic just took those old r-12 systems and filled them with propane. They worked and propane was cheap enough that it didn't bother if it leaked. He also converted several r-12 systems to r-134.

Basiclally, he just drained the oil, changed the fittings, sucked the thing dry with a vacuumn pump and refilled with new r-134 oil and r-134 refrigerant. They all worked.

Never hbad any problems with the propane systems, either.
 
Thanks men for the advice...........I found some R12,didnt think it was still around,but its $35 a can,probably go that route,I dont have a vacume pump,would'nt know how to use it if i did,but i can dump a can of R12 in it.
good luck

I think I would get the system pressure tested first Haymaker. It would be a waste to recharge and then find a major leak like I did last spring.

NAWWW think I will do like you,put R12 in it and if it leaks out then get it pressure tested..............called optomistic thinkin :wink:
good luck
