AC Compressor Repair — DIY compressor fixes
Learn how to perform your own AC Compressor Repair
AC Compressor Repair isn’t rocket science. Most DIYers can handle replacing the clutch, clutch coil, pulley bearing, pulley, case seals, flow control valve, and even the front seal. You don’t have to evacuate the system to perform clutch or pulley bearing replacement. But you don’t have to evacuate the system if you want to replace the front seal, case seals, or the flow control valve.
You’ll need a few tools
• Clutch puller/installation tool
• Clutch plate holder. Since you probably don’t know what size puller tool you need, you may be better off buying a complete kit for less than $50. This kit from amazon.com costs just $32
How to replace an AC Compressor Clutch
If you’re doing an AC compressor repair, you’ll have to remove the clutch. To do that, screw in the removal tool and hold the clutch disc with the holding tool.
Remove the retaining nut on the compressor shaft while holding the clutch disc with the holding tool. Then install the clutch disc puller. Use the clutch disc holding The clutch pulls right out exposing the coil and pulley. Remove the clutch coil. If you’re having clutch issues, replace the clutch disc, pulley and clutch coil
and together.
Replace the AC pulley bearing
On a complete AC compressor repair, it makes sense to replace the pulley bearing. To do that, you’ll need a pair of snap ring pliers to remove the retaining ring.
Remove the old bearing and install the new bearing. Re-install the retaining ring. Make sure it fits into the groove
Replace the AC compressor shaft seal
With the pulley off the compressor, you’ll be staring right at the main seal. If you find a lot of oil around the shaft, you’ve got a leaking main seal.
To replace the seal, first discharge the system. Then buy a new seal and a seal installation tool. The installation tool is a sleeve that fits over the shaft to protect the seal from installation damage. Oil the seal with AC oil and then slide it into place, making sure you don’t nick the green rubber O ring. There you go, you’ve just rebuilt your A/C compressor.
