This discussion started on the 'other' board but I thought others here might be interested as well.
In my search to find parts to fix my AC system I'm looking at converting to a Sanden rotary compressor system. Some later QV and Euro 328 cars had a rotary AC compressor system. The rotary compressor is much more efficient than the old York system. I am also going to replace the dryer and possibly the Exp. Valve as well.
Carr Autoparts is right down the street from Pinnacle and Steve said he knows JR.
I was at Steve's shop today and came home with the parts I/We think will be required to make the Sanden Conversion.
I bought the compressor, adaptor bracket (which I may or may not use - more later), PAG oil for R134a conversion, some AC Flush, new fittings to cut/mount on the existing hoses and a new drier.
My quick hand fit leads me to believe the Sanden Rotary will fit just fine with the adapter.
The drier is a UAC RD1134. The ports are the right size and it's a little smaller DIA than the Hansa that was on my car. It looks like it will fit fine but since the diameter is smaller the bracket holding the old one is now useless. I may bring it back and try search through Carr's supply and see if we can find a better fit. If all else fails I'll call T-Rutlands and order the correct one for $90 (OUCH!!!). Unless JRV has one in stock in his shop??
I may also (at Steve's recommendation) remove the expansion valve and bring it to his shop to attempt to find a suitable replacement. It looks like the valve should come off fairly easy. The main reason for this is so I can flush out the entire system instead of just the condensor side (the evap side would require that I remove the valve in order to flush it and since I'm going this far I might as well do it all correctly). Steve said if I flush everything, and replace all the O-Rings then I'll be sure to have a really complete new/retro system and it will only cost a little bit more than I was already going to spend anyway (the cost of the exp. valve).
Unfortunately I've had Dad duties last night so I was not able to work on the system and provide more information.
The parts I bought were..
Sanden Compressor - SD7H15 $269
Drier (UAC RD1134) - $29.95
York/Sanden Mount ** - $49.95
PAG Oil, 22oz of AC Flush, new fittings ~ $33.50
Total Bill with Tax was $412.24.
He has the York compressor with out a clutch for $229 (so if you've got your clutch still you could buy this and attach yours). He could not find the correct clutch for the system nor the pulley so if you don't have it you'll have to find one from Ferrari (which I don't think they have) or come up with one somewhere else. Sorry, but right now I'm not going to part with mine until this project is done and I'm sure I can live w/o it - and even then I may keep it). My compressor is actually a Apera built under license from York in Italy.
** If I had a camera I'd post a pic of the adapter. But it's basically a flat plate with two ears. The flat plate mounts flush against the existing York/Ferrari mounting bracket in oblong holes to facility alignment of the pulley/belt. The rotary Sanden mounts on the ears. Unfortunatly quick measurements lead me to believe that the system will only have mounting points on the top. I was hoping I could mount a second bracket on the bottom to give a more secure installation but I don't think I will have enough room between the existing brackets to mount 2-adapters and the new compressor. Since I have a neighbor with a plasma cutter, and a welder, I may make my own brackets to mount the system on so I can attach it at two points. I also found mouting brackets for the Sanden at Ferrari UK, but the parts would be close to $400 for everything which is just a little bit much for some brackets IMO. I'm going to print out the picture and maybe see if my neighbor and I can fabricate something close.
When all is said and done I'll be sure and document this for future owners/converts.
The Sanden is a much better compressor (According to Steve Carr) and he said I'll be much happier with this system over the York. The only small issue I see so far is that the pulley is slightly larger than the York and your AC belt will ride a little lower on the pulley, but not on the bottom so the belt/pulley will still be working like it's supposed too. Also, I'll need to find a shorter belt. Not to mention you car show guys will be losing concours points.
I'll dry fit everything tonight and see if this is really going to work. If all looks good I will go cut my lines and install the new fittings (you will not need new lines - there is plenty of extra to cut off the existing fittings and install new R134 fittings/ports. You want to be sure and leave extra though so you can swing it out of the way when you do your belts - which should not be a big deal since it's 1/2 the size and WEIGHT of the York!).
