A/C compressor R&R time?

A/C compressor R&R time?

Postby nonhog [OP] » August 9th 2017, 8:55pm

I know a few members are techs and I was curious what flat rate time is on a comp. R&R.
I best factor all the O-rings, Schrader valves, receiver/dryer, anything else?
I may pay to have it done but am on the fence.

Thanks in advance

This information is available from virtually every local library(in my experience), using Chilton Library. Most even allow access from home, some you don't even have to login ;)

The Air Force link used to work for pretty much everyone, seems they have changed it.

ProDemand flat rate for compressor is 1.8. Add .4 for filter. .5 for the dryer. 1.4 for evac and recharge. And then who knows how much more for o rings. that's just going to depend on how many you try and tackle.

Thanks T&B that helps a lot.
I suppose since I tackled a steering gear box (twice) I could do a compressor. Now do I want to?
Speaking of O-rings I know I just read on here somewhere (probably more than once IIRC) that its a good idea to do all the O-rings. My concern is that possibly opening a can of worms? Or just good insurance. Sure don't want to half *** it. The tech at my shop says don't bother but he is use to Toyota's.

Thanks AW,
I am searching for "kits" like one member used from Rock Auto. My year they don't seem to have. Amazon has a kit that is not as complete but might be a way to go. I'll be searching now.

As far as o rings are concerned, I just replace the ones that are involved with whatever I am doing. like if I replace a hose/line, I install new o rings on that hose and if I replace the condenser I replace the o rings on that hoses that go to it. Simply replacing ALL o rings just cause is over kill IMO.

The compressor SHOULD come with new o rings, and the dryer SHOULD come with new o rings.

I have rebuilt a few systems now and I feel it's definitely worth the extra time and trouble to do all of the o-rings. It does open a can of worms but only if you're not at the proper skill level to tackle the job. Disconnecting all the lines at once gives a great opportunity to flush each line separately and gives peace of mind knowing that all those connections are sealed with new oiled o-rings.

Make sure you flush with filter/drier can removed. If there's a "muffler" can be sure you empty all the flush from it.

I have bought the "kits" but I always make sure to have a large assortment of HNBR O-Rings handy just in case the kit falls short.

I also wouldn't bother rebuilding a compressor. For $200 it's worth replacing.

Don't forget to buy PAG oil, preferably with dye.

Any tech who says "don't bother" has become too accustomed to looking forward to future business. When I repair something I expect to never touch it again.

Cargo, some good points however I cant disagree more with you on "any tech" statement. I've been at a dealership for 31 years in service and in parts (now)
I know most tech do not want come backs. Not worth the hassle. So if they have a suggestion its usually because of experience.

Don't bother replacing aged rubber parts in a pressurized system?! :rofl: OK. Makes sense to some I guess. I was just trying to point you in the direction of an overhaul, not a spot repair. Seems you know what you're doing. :whistle:

I never said "don't bother", all I said was that it was over kill to replace them all. And since your the king of over kill on this site, I am not surprised you disagree with me.

Its simply depends on how much he wants to dig into it. I wasn't talking him into or out of an overhaul, and if he wants to go further then by all means.

The point I was trying to make is, at the very minimum, don't reuse o rings and if something comes apart to be replaced, then you should also replace the rings.

CC you missed my point. I wasn't making a statement on weather I would or wouldn't replace O-rings that is a decision I will ponder. My point was your painting all techs that don't follow your thoughts as looking forward to more business as BS. That's all. I did also say you had good points.

Moving on....

While I expect my mechanic to do a job right, I also like a mechanic who knows I don't have infinitely deep pockets and that the costs of doing some repairs simply might outstrip the benefits for the average consumer. Now, I know leaving some things un-repaired leaves the possibility of a come-back repair but if the probability of that come-back is like 1% and the additional work is hundreds of dollars, it probably makes economic sense to leave it alone for the average consumer.

I really like to overkill things too, but that's mostly when I have either time or money. Most people don't have much of either.

There's no right or wrong here. :D

It sounds like a "good option" to to preventatively overhaul the system while it is apart getting a new compressor. But certainly many mechanics will just replace the bad part, as they are paid and expected to do. I suppose they "could" offer the overhaul option and let you choose.

I've replaced many compressors in my life and never changed all the rest of the o-rings. But I absolutely change the orifice tube and dryer, so that covers some of the other o-rings anyway.

Your level of preventative maintenance is up to you!

Physically swapping the compressor on a Gen 2 is fairly easy. The other time will be spent changing the other parts, and vacuuming down and charging the system.
