AC Compressor Bearing Replament (1 Viewer)

[sleepycruiser]

How long of a job is replacing the bearing and how many bananas? It’s getting hot outside and while my AC cools quickly and cold the noise is crazy. Still hoping this is the issue...after a year.

Check my build thread for instructions. I just did it a few weeks ago.

What is the make of the bearing? Any Japanese bearing is the way to go. I once used a Chinese on my corolla and it lasted 6000 milrs and made noise again. I saw a guy selling nsk bearings on ebay

This is what i used:
30BGS10DST2 A/C Compressor Ball Bearing 30x52x22 DAC30520022

Looks like an unbranded bearing. Contact the shop and ask for a refund. Send the video you made

Called the seller and they will replace it if its manufacturer defect. Gonna remove the pulley and listen to it. But when i first installed it i gave it a few spins and didn't hear any grinding. I wonder if the pulley is making contact with the 'cover'?

With a load it can make noise. My old bearing made the noice only when clutch is engaged.
Try not to remove and install the pulley on the compressor shaft multiple times as this cam cause the shaft (where bearing rests) to wear out as it is a soft alloy. I had that in my corolla and the whole pulley assembly started to move on the compressor shaft (bearing didnt fit tightly on to the compressor)

K, ill just leave well enough alone then its only on occasion that it makes the noise.

Ordered a bearing....hopefully tackle this next week.

 

[sleepycruiser]

Bearing came in. Any random tips before I begin this? Probably will start it tomorrow after work...maybe. I can’t be without my LC since it is my DD. How long of a process is this?

Two hours. Get this to help if your c clip tool wont do the job. This made it super fast using the large straight pick tool. See my build thread for help.

I am having trouble getting the 10mm loose. From this view from above I tried to turn it counterclockwise and could not get it to come loose at all. Not a good way to keep the pulley from moving while the 10mm is on there so I tried to use a screwdriver and a pipe and still couldn’t get it loose.

 

[bucfl]

I used a really long screw driver to jam it so it didn’t move. Or try with belt on(?).

Righty tighty lefty loosey

 

[sleepycruiser]

Definitely turning it the right (lefty loosey) way...lol.

The only place I can get a screwdriver in is between the faceplate and the pulley track....still couldn’t get enough stability so the pulley wouldn’t spin.

 

[bucfl]

Look at my thread for how I used the screw driver. Does your faceplate look like mine? They look different.

 

[sleepycruiser]

Yeah, I used your thread when I was trying to figure it out but your faceplate looks completely different than mine.

 

[bucfl]

How about with belt back in?

 

[sleepycruiser]

I didn’t try that....I might try that when I get back in town next week....stinks bc I am driving to alabama and it is going to be hot. The AC works fine just makes the crazy noise. It’s been over a year.

Did you end up getting the bolt loose with the belt on?
I'm doing this job this afternoon.

No. Right before I was going to tackle this I hurt my elbow and I haven’t been able to get much torque on anything in about 6 months. I am going to have someone else do it or try again in the next month or so.

 

[oldcavendish]

I ended up leaving the belt on and used a 3/8” breaker bar, but held the clutch plate with my hand it came right off. There wasn’t much torque on the bolt.
