Very good information to know. I saw the shims listed on Messick's site as I was looking to price the clutch and complete unit. The local dealer had already told me that they only replace the complete compressor and not just the clutch. The proceedure I used last night certainly wasn't by the...

I have a set of old trusty gauges however without the compressor kicking in I really didn't know what they would tell me. I was going back to the 70's looking to short across the low pressure switch to make it kick in and to my surprise when I finally was able to disconnect the connection at...

There may be some excessive wear due to slippage from the past few years however I really don't know when and how it got out of tolerance. It may have been off from the factory. At this point I have identified the issue and now will be looking for a new clutch source should I need it down the...

I actually went to the local dealership yesterday morning to see about getting it fixed "professionally" only to find out that other than adding freon a few times they really didn't have the shop knowledge from prior jobs to fix it.

Thanks for the reply but looking for someone who had experienced an issue with the clutch not engaging which is part of the diagnosis. Had the tractor quit cooling and not started back cooling again I would be looking toward the compressor, low freon or something mechanical. Currently I am...

More than you wanted to know response from personal experience in fire trucks. A couple of years ago we started using Bio Kleen (Power Sevice) available locally at our auto parts store as it was the only brand available off the shelf. I followed the manufacturer's recommendations for the...

The air conditioner clutch recently stopped engaging and needless to say the cab got hot. I turned the tractor off for a couple of hours and when I restarted it the air once again worked and stayed working for two hours (remainder of day) when I put it back in the shed. Got it out a couple of...
