Am in process of rebuilding/converting AC system to R134A.
I have a couple of basic questions:
1: Will be purchasing conversion couplers for the low and high side service ports. ACKITS website has two versions for the high side, a 7/16-20 (1/4") 16 MM Coupler, OR a 3/8-24 (3/16") 16 MM Coupler. So how do I know which one I need. Is it as simple as measuring the thread on the existing R12 port?
2: This car has a York/CCI model 210 compressor. Will need 2 special "Rotolock" teflon seals for the connections at the head, York P/N 028-07146, and a new suction screen, York P/N 026-19841. Are these parts available from ACKits? (not currently in their on-line catalog).
Your talking about the adapters. Simple way to tell, use you R12 hose for servicing an a/c system. If the high side hose attaches to the high side port it is the 1/4 adapter. If the high side hose is too big for the service port you need the 3/16th adapter.
You probably have 1/4 ports on both sides. I think 3/16 ports were not common until the late 1980's when lawyers decided that it was too easy to blow yourself up by hooking a can of R-12 to the wrong port.
Simple way to tell is take the dust cap off of the low side and see if it also fits on the high side.
Take the shrader valves out of the stock ports before putting the adapters on. The ones ACKITS sells have their own shrader valves.
Thanks guys. I checked the caps, both same size.
Any idea on the other question, regarding parts for the York compressor. Can ACKITS.com find these for me or should I look elsewhere?
Should have the Teflon seals and I'll check on the other Monday when I get back at the shop.
If you could take a look at availability/price the 3/4" tefon seals I was going to place an order in a couple of days for a few items.
Also need Qty 2 oil drain plug o-rings (CCI/York part # 028-21549).
I can get the strainer from Mercedes if you don't have in stock.
Got side tracked today, I just sent myself a reminder to look into these items in the morning.
we do have the o-rings that you need. The oil drain plug o-rings part# 40-02514 and the Teflon seals part# 21-26051. If you wish to place your order online and add these items in the additional info box we can add them to your order for a few extra bucks as they are not listed on web.
Will get on ACkits and place order when I get a few spare minutes. Many thanks for your help.
Placed order today for seals and some other items. Thanks for your help, and thanks for all the great info on the forum,
