Rebuild AC compressor

williet98248 on Sun August 30, 2009 2:48 AM User is offline

Year: 1983
Make: honda
Model: accord
Engine Size: 1.8
Refrigerant Type: ?
Country of Origin: Thailand

I don't seem to be able to find the answer to my questions by browsing the forum. The original AC compressor, a nippondenso unit #4E 8119 has failed. It made a heckuva loud noise for several months and then stopped working. I have taken the unit apart. It appears that the insulation on the copper winding has melted. I believe this is the electric clutch? Upon disassembly the interior of the unit seems OK but I am assuming I would need to replace the seals and o rings too. Can the clutch be replaced? Is it financially feasible to do so? If so, where can I find parts/seal kits for this unit? Any info would be greatly appreciated.

The noise was probably the pulley bearing failing, you may have needed just the clutch..But since you took it apart, you won't be able to put it together without everything you stated, it would be cheaper in the long run to buy a reman compressor.. Check this page for your compressor even though it's for an 84 accord, it shows the two kinds of compressors used back then.. you can e-mail the guys at ackits.com if you have any questions regarding your compressor..

Well, he is from Thailand, have no idea about replacement parts in that neck of the woods, Venezuela is indubitably insane of any replacement part for a vehicle. Maybe some good grade of aviation gasket sealer will work with the old gaskets. Clutch coil can be rewound if you are desperate, same wire gauge, same number of turns, with some epoxy to keep it from rattling.

Car came with R-12 refrigerant, only recommend Honda AC fluid in these things, can you get R-12 in Thailand? Some countries are not concerned about a hole in the south pole ozone layer that never was proven to be the fault of R-12. Idler pulley bearings are fairly standard, question of finding one that is the same size, dual radial double sealed bearing.

Thanks to Chick and Nickd for quick and helpful answers to my problem. I too thought it was just a bearing but when I talked to Thai mechanics they told me to replace the entire unit. I decided to just let the unit fail before replacing the whole thing. Wish I had done some research before failure. Rebuild parts are probably available here in Thailand but not speaking or reading the the language makes it difficult. Taking your vehicle to a Thai mechanic can result in some very interesting fixes. They fix the symptom not the problem. No deductive reasoning on their part. I once had a Thai motorcycle mechanic replace the fork seals on my motorcycle three times before I pointed out the corrosion holes in the tubes where the oil was leaking out. "Oil leak? Replace seals!" A minor weld and buff fixed that problem. I usually end up importing oem parts from the US or the UK for my car and motorcycles and installing myself or having a Thai mechanic install for me. The problem with ordering a reman compressor from the US is that it will cost about $150 in shipping and customs fees alone. I will check the price of clutch and O ring kits and see if it makes financial sense to repair my unit. I can get a reman unit here for about $150. NickD; I am probably not so desperate as to try to rewind the clutch coil although it is most likely the bearing is available somewhere here on Phuket. Thanks to you guys for your help and recommendations.

Followup: O ring kit is available but can't find a clutch for my unit. A reman unit from ACKits.com is over $300 plus the shipping and customs fees. Not a viable solution. Will buy a reman unit here in Phuket for about $150. Thanks again for the help with my problem.

they must have scrap yards there, try to find a core with a good clutch, and just switch the clutch assembly...

Re. scrap yards. I have never seen one on Phuket, maybe in Bangkok which is 600 miles from here. There must be scrap yards but again the language barrier is tough to surmount. Whenever I talk to my Thai mechanic about used parts he just shakes his head. I took the car to an AC shop yesterday and they put in a reman unit (4800 baht or $141) plus replaced all the hoses, belts and some other parts with a complete refurb for a total of 11,000 baht or $323 including the labor. Bit the bullet. But dang! It blows cold! And it is hot in Thialand.

Thanks for your help.
