summer is comming! an air conditioning saga

No, not that Summer...

but it would be nice to get some air conditioning rocking in a 510 before it gets hot. now, I have been saying that for the last decade....
I have a stock dealer option under dash air conditioner(evaporator with blower and controls). ImageI have yet to split the case to see how the two lines connect to the evaporator but they did connect to the dryer and condenser with hose clamps? when looking at new condensers they have male o-ring fittings with a #6 #8.. ? can I go from a fancy new fitting to just a hose clamp?

the other day I found a company in FL that makes a Compressor Upgrade Kit for the 240 60 80z cars.
https://nostalgicac.com/compressors/com ... e-kit.html

the bracket looks fairly simple, but would the pulleys line up? it is slotted for l26 to l28? belt diagram don't jive with a l16 or l20b... the z24's 3 grove needs the front grove cut off to clear a stock rad, but most troubling is how slow the compressor will spin if it runs on the small inside grove of a stock L16 two grove pulley. would it be too small ?
hmm they also offer bits of brackets.... that would save a lot of file and fit
ImageImage
so the dealer option condenser was 10x18x2in and sat very snugly between the rad and the core support rod.
the opening on the rad support is 12.75 x 19.5 but with a narrower condenser you have to the the ability to push it to 26x13.5 before the grill brackets interfere.

Boy it is hard to apprentice off the internet.... so Im using this thread to sort through the info and hopefully get some direction.

sanden 508 compressor service guide http://www.sanden.com/productlibrary/ma ... _Rev_2.pdf

dug a little deeper into the evaporator box and uncovered the hose connections. can anyone tell me the name and size of these connections? wrench size of the fittings = 3/4, 7/8, and 1in ? will the expansion valve need to be changed and if so do I replaced with an orifice tube ?

I'm a fan of EZ-Clip fittings for AC work. Go see New-line hose, they have all the fittings you need and can help you adapt to your equipment. New-line.com

I've done several Z and 1 510 using vintage air evap boxes (compaq and mini) and love EZ-CLip hoses. DIY, smaller hose, tight bends.

i have pretty much a full selection of ezclip stuff in stock all the time i have at least 20 fittings here- just got a 50' roll of -6 too..
at least the nissan evap has an expansion valve on it- you might find that the "old" condensor wont work well for r134- id replace it myself-
i dont think its common for expansion valves to die so it should be good to go- need an external dryer and a switch-

ez-clip .... I thought I would have to drop a few hundred on a set of crimps. when apprenticing off the internet your only subjected to the parts your search engine offers up.

thanks for the recommendation guys

hey cartel im out in langley almost every sunday .... ?

I do plan on getting a new condenser ( looking at a12x20 CNFP1220 ) , dryer and (corrector me if I'm wrong) a switch...? (something called ac pressure transducer?) . along with a high side tap and low side tap.

do I bother with a used pump should I buy new ? and if new should it be a SD5H14 or a SD5H11

I'm a vintage air dealer and keep most of the stuff in stock. Dryers and switches and generic condenser.
Today taking kid to Canucks game today but some weekends I'm there.

If I sell the parts u can use the crimper.

On a 240Z L24 6cyl we used a ZX cast aluminum AC bracket (earlier Z is heavy cast iron!), made a simple spacer to adapt the compressor, hung a NEW Sanden AC compressor (SO MUCH more efficient that the original York gigantic monster POS compressor!), flipped the dealer installed condenser so both line fittings were on DRIVERS side, a universal receiver drier on DRIVERS side lower inner fender (below ign coil), had custom hoses made, got a nice universal NEW firewall/bulkhead double (two hoses) pass thru fitting, custom hoses to the original dealer installed AC evaporator box up under PASSENGER side dash. Luckily the evap valve & evap core were in good condition, otherwise you would have to repair or fabricate, cuz there are no factory part #'s for replacement parts! Hope that helps some!

Nathan Marshall in N. Carolina makes a nice bracket that allows you to bolt on a Modern Sanden compressor to a L 4 engine. He and the”510s R Us” gang have done several successful installs on 510s.

I have one of them. Maybe one day I’ll get it installed.
Enjoy The Ride!

Dave do you think Nathan's bracket could be used to adapt an alternator on the DRIVERS side with some lighter mods and/or another adapter? velvethammer is looking to do this in his thread on an L20B, which has a different cast bolt pattern on the block than the L16/L18............

RMS yup, it's a nice cast aluminum bracket that should bolt up to all of the 6cyl L series! FYI the 4cyl vs the 6cyl bolt pattern cast into the front DRIVERS side of the blocks for accessories ARE different. I bet somebody could make it work on a 4cyl, but again, should fit all 6cyl!

I’m not sure. I can pull it from storage and take a few pics.
