a/compressor question

So the magnet thingy inside the compressor pulley got all screwed up. There were dismembered bearing parts along with possible snap ring chunks (there was no front snap ring to remove) stuck in the magnet thing. It caused the pulley to seize, blow the engine bay a/c fuse, and snap the belt. I got everything off the compressor shaft. Everything was going fairly smooth until I damaged the end of the shaft. I managed to snap a piece off the end of it, leaving about half of the groove exposed. I will attach some photos. They are in the order that I took apart the assembly so you can see at what point in the process I damaged the shaft.. I didn't want to have to replace the compressor. What are my options or am I cooked? TIA

 

That compressor looks pooched, I don't think it's worth trying to save it.

 

If you're willing to accept the risk of throwing the belt and it's components again and having to replace the compressor and possibly more you can try it but, honestly i'd replace the whole compressor at that point for the long term peace of mind instead of having that in the back of your mind that it could come apart at any moment.

If less than 25% of the groove were gone I would try it but not with that much gone

 

Ok. I'm just glad it has a separate belt for itself

 

Yeah, I spent a few hours removing it all and I don't want to have to it all over again. I'll have to figure out what I'm going to do about the freon now... thank you for the reply.

 

Ewe
Yeah done. Sorry

that cracked off portion is where the snap ring holds inner two parts of clutch

IMO
Don’t blame yourself, the inr 2 parts(magnet and pulley) are really bad.
I would blame the cracked shaft on that
Weakening the shaft from failure of pulley bearing

 

I would replace the compressor.

 

I was thinking about that. I spent several minutes looking for the snap ring with my pliers until I finally realized I had no snap ring. Previous owner forgot to put it back in? Possible, but also possible that it broke and dislodged itself, weakening the shaft end in the process, and causing catastrophic failure of the rest of the components. I could've been more careful too instead of using a hammer and prybar to remove the pulley lol.

Anyhow, thank you for the response.

 

That's what I feared I will have to do. I'll have to take the truck and a new compressor to a shop since I have no way to deal with the freon legally.

 

Yeah I understand

just make sure that you get charged for Evac and Recharge only
(Typically 1.5-2.0hrs mech labor rate)
Shop will take your Freon/oil

Then u install new compressor and return to shop. They should not charge you for additional Freon (they already have it!)
Might charge additional to vacuum system again.

in addition, since you know system will be opened, go ahead and buy the $12 Autozone pack of green AC O-rings and replace as needed. Get 2 new schrader valves for the H/L lines too.
In my area I had to insist Oriellys employee to look in the back for the $3each S valves
(instead of ordering me a $175 AC line)

some guys will recommend a new dryer too
Depending on the price, I would recommend that as well
Let everyone know what happens!!

 

Ok, I had to look up several of those things so I know what I'm asking the autozone guy for. The O-rings I'm guessing are for the refrigeratant lines, correct?

I'm a little confused when you say evac and recharge. I thought recharging was the very last step to the whole process?

Last question, should I trust an aftermarket one or go with oem? And it's the delco brand the oem version? Thanks.

 

Recharge is the last step, its just the general name they use for billing. It's why he was saying they shouldn't charge you again. It'll probably be the menu pricing. Just explain you'll bring it back to be recharged afterwards and you guys can figure out the pricing together.

I would go aftermarket if it was an OEM supplier like Delphi, AcDelco, Denso(preferably),Nissen. If those options aren't available i'd go OEM just because for most people evac and recharging isn't a diy task so I figure those brands have the lowest chance of failure.

you can find your repair instructions here at this link too I don't know what engine you have or i'd link it straight there for you https://charm.li/Toyota/2002/

 

Your in the PNW so AC isn’t a real pressing issue, saving a 23yr old compressor is not a good option your not 100% sure there is no damage inside of it. Im spitballing here but if you take it to a shop more than likely they are going to say flush system, replace compressor and filter/dryer.

 

Agreed. Replace compressor when you can afford.

 

I may be in the wrong here but if I got this job in the shop I would just quote a raw r<&>r for the compressor. If I pulled the discharge line and saw black death then sure i'd ring the customer up and explain why it's a good idea to flush the system etc,etc but more than likely the pulley bearing got worn, loose wobbled into the electro-magnet and started this chain reaction of carnage.

It's not a bad idea to flush the system, replace the dryer and metering device with every compressor but here I don't think that would really be necessary.

 

I dont think your wrong at all, we’re seeing it from different climate perspectives, we dont dull to many ice scrappers down here but our AC systems get a work out.
