Sanden Compressor Conversion
So my compressor is leaking like a sieve. Last year I had flushed the whole system, replaced the expansion valve, and replaced as many o-rings as possible only to find out that it wouldn't hold a vacuum. Since it was near the end of summer I threw a couple of cans of R134a in and called it a day. Worked great for about a month.
Well summer is here again and it's time to fix it as I daily drive my car and can't stand driving around all sweaty.
So here is the build list so far:
Sanden 6629 SD5H14 Compressor - 7 rib pulley and ports on top
(Newer replacement for the NLA SD508 Compressor)
https://www.acparts.com/09-6629-p-301420.html - $164 + Shipping
Mount kit for the compressor - includes the brackets, hardware, new belt, and some fittings and hose that I will probably not use.
http://www.paragon-products.com/A-C-...44.126.009.htm - WAY overpriced at $150 + Shipping
Drier - you can get this anywhere
$15 - no sight glass
$60 - sight glass
Since I am thinking of picking up one of those universal condensers I am still undecided on fittings and hose size.
Does anyone know what the factory hoses sizes are that go to the compressor? Is it the standard #8 discharge and #10 suction?
If I do stick with the factory condenser can I reuse the inlet fitting by cutting off the old hose and ferrule? Are the fittings SAE or Metric?
Also, should I be using aluminum or steel fittings?
Thanks,
Sixline

What about the inlet? My plan is to cut off the factory fitting and crimp on a new one to the old hose.
Also if I pick up your condenser what do you normally do for the line going to the drier?
This is what my hose/line looks like.

for my piece the line to drier re-uses the factory drier end but has a fitting matched to the condenser.
i don't get many chances to be at the house where my tools are for that item though so it would have to be something planned out if you wanted one.

Going to have to pass then. Will definitely keep you in mind when I need my A/C colder.
FYI found the conversion kit on Amazon for about $23 cheaper. Did the Amazon Prime trial for free 2 day shipping too.

They look like steel to me, anyone confirm? I suppose it doesn't matter but thought I would be consistent.
V2Rocket_aka944, if you don't mind sharing, whats your method for reusing fittings?

So I got this finished. A/C is working again and no leaks!
Here is the final parts list:
Sanden 6629 SD5H14 Compressor - $200-$250
Mount kit for the compressor - I didn't use the belt, hose, or barb fittings that come with it. - Currently $131 on Amazon
Drier - $13-$60
3 cans of R-134a - $9-$10 a can. I bought 3 cans for $26.55 on Amazon.
Long Shank #8 90 Degree Female O-Ring Beadlock Fitting - $10 (Connects to the condenser)
http://nostalgicac.com/fittings-hose...ong-shank.html
#8 90 Degree Female O-Ring Beadlock Fitting - $5-$6 (Connects to the discharge side of the compressor)
#10 90 Degree Female O-Ring Beadlock Fitting - $5-$6 (Connects to the suction side of the compressor)
2 feet of #8 Goodyear Galaxy Barrier Hose - $7-$8 (Not reduced barrier. You can use the length of hose that comes with the compressor mount kit but mine wasn't very flexible.)
*Mastercool 71550 A/C Hose Crimper Tool Kit - $150 new on Ebay.*
Now this isn’t really required but I didn’t want to use any hose clamps. The line from the compressor to the condenser is made off the car so you could probably find someone to crimp it or borrow the tool. The suction line is crimped to a hard line on the car and cannot be removed. I was doing a turbo and alternator swap at the same time so I had tons of room to get this tool in there to crimp the suction line (image below). If you remove the alternator you might be able to get it in there but I don't know. You might be forced to use hose clamps on that one.
Vacuum Pump and A/C Gauges - I already owned these.
Total cost for me: A little less than $600
