I have an 89 LXi hatch with ac problems. It was recommended by a mechanic friend to replace the compressor and change to r134. I have been reading this forum and discovered that Keihn Compressor(the one my car) should not be converted to r134. But what about the remanufactured ones. Aren't the seals and all replaced.
They are all replaced, but the Keihin isn't built with the pressures of R134a in mind. Save yourself the trouble and convert to the Nippon Denso compressor. It's a much more robust unit.
yes the denso unit is going to handle the r134a better. i did convert the keihin to r134a and it only lasted 2 months before it gave up.

A good search of posts here would show a few mixed results with R134a in Keihn compressors. With only a few exceptions the vast majority of those who have tried R134a in Keihn compressors have not had good long term success. If you put a keihn compressor back in be it new, reman'd or used, R12 should be put back in. If you convert to a Denso you have more options, R134a being one of those options.
If you convert to a Denso you will need, compressor, compressor mounting bracket with all bolts and hardware, both hoses, dryer/accumlator (should be changed even if you put a keihn back in). Note that Honda still makes a rather pricey conversion kit with all of the needed parts including a new denso compressor. The Honda conversion kit was my final choice to address my Keihn compressor problems earlier this year.
They can have my Accord when they pry the steering wheel from my cold dead fingers.

Could someone tell me who has the patent on R12 and R134?

Thanks. That's what I wanted to know. On a side note after posting. I talked to my brother,who is in the air bussness. He has some R-12 he forund in storage, And using resources from this site(it is awsome) I found a good deal on A Keihn Compressor. I am going to Replace it with that,replace the o-rings(if possible) and the dryer and recharge with R-12. Thanks again.
Sounds like a plan.
If you don't want any leaks, replace the O-rings for sure, their green. Pull a vacuum after you replace that compressor & see if it holds for 10 minutes. Generally, any reading that drops below -30 hg, there is a leak.
When you remove the compressor, don't forget to refill it with Ester or what ever Klein requires. If your brother has an oil injector, fill it up to the top with 2 oz., add more if needed. (after first charge)
.
Thanks. I will do that. And I am planning on replceing all O-rings. In 1993 I bought An 84 LX hatch with 60,000 miles for $500 because the lady said the air only worked about 2yrs. I replaced all O-rings and drove the car 10 more years and never had air problems.
