I forgot to add, it was 84 degrees outside and really humid.

Compressor was making bad noises. My buddy cut the belt. AC was short cycling when the noise started. Still made noise with AC turned off. System was empty this morning when he brought it over. Took the orfice tube out and it was clean so we proceeded with replacing the compressor, orfice tube, accu...

I changed a hose on a car yesterday and it was my first opportunity to vacuum with a micron gauge. It got down to 270 microns. My trouble was coming up wth a way to isolate the system and gauge. I'm thinking I need a tee with two metric male connections and one SAE? My pump is an older one, but stil...

When using a micron gauge, where do you connect it to the system? If a system is sealed up good, how low should the micron level go when vacuuming?

Thanks,

What's the difference in performance of cheaper couplers vs more expensive? I have one good set of Snap On gauges and several sets of cheap gauges. The couplers on the Snap On set are showing signs of wear. I bought a set of cheap couplers for cheap gauges, but I haven't had a chance to try them yet.

We have cold AC in our fire engine again! Been working good for about a week. It wasn't working very well after we charged it. Had to change the expansion block and vac and recharge. Lesson learned.

Correct.

Thanks for taking he time to help.

I have spoke with Tim at ACKits about this. I sent him some pictures of the compressor discharge and suction ports. No metal visible. He thinks the clutch failed possibly because of low battery amperage. Thinks we should be ok replacing the compressor and dryer only. He saved us a lot of money on th...

I got the compressor off yesterday. I pulled the sight glass out and there was no oil. No evidence of metal in the suction or discharge ports. Thinking it got hot and ruined the clutch. Would it be safe to put on a new compressor and dryer then vac and recharge?

I work for a small town fire department. A compressor on one of our engines has seized up. Is there a way to tell what type of condenser it has? I'm also looking for suggestions for places to find parts for big trucks. The compressor is a Seltc TM-31HD The engine is a 2003 E-One Typhoon

Thanks,
