Hello I am new to this forum. I have a 4440 that I put a new a6 style aluminum a/c compressor on two years ago ,and never had a minutes trouble or recharge since I put it on. Last week I was brush hogging and when I got done for the day I blowed the radiator and condensor out same as i always do, and the next morning I got on and my compressor was locked up. I called my mechanic buddy and he said the compressor was shot and that I should go to sanden style compressor with extra condensor kit, so I just got all the parts in and we going to put it on today. I was wondering if anybody had tried the sanden style compressors on older tractors and what kind of luck you had? Thanks
