I don't know what to think about that York pump deal? On the ag sites, when someone asks about converting their old York pump equipped AC system to R134a,about the first thing someone says is that you gotta toss that old York pump in the trash because the shaft seal will not hold R134a,they say Sanden is the only way to go. My old 1480 IH combine has been on R134a for 10 years with the york pump and aprox 50 ft of old R12 refrigerant hose that dates from when the combine was built in 1978. 1 can of refrigerant with hose and O ring conditioner(not stop leak),then the rest just off the shelf R134a. I always replace the tired,relaxed shaft seal that leaks around the shaft with a new $9 NAPA seal which gives me a combine that leaks about 1--12 oz can of R134a per year. I dont think thats broke,so I ain't gonna fix it with a new $300 Sanden rotary pump.
This summer the O E Sanden pump on my Steiger Panther died,and the NAPA guy said a rebuilt is $275 W O the clutch,or $325 for a new one complete with clutch. I have a pile of good used York pumps that I picked out of the salvage yards for $5-$10,and when I found one with the correct fittings to fit in place of my dead Sanden pump,I decided that it was worth fabing a mount bracket and the cost of a new pump seal to see if my luck with the Steiger equals that of the 1480 combine. The bracket was an easy 1 hr project,the original belt and hoses all fit and when I charged it,the performance was better than with the Sanden pump. With 75 degree outdoor temps ,and the blower on high,vent temps went right down to 35 degrees. About the coldest running retrofit I have ever done. I ran it for an hour or so to polish in the seal to get the best leak free fit,than parked it(seeding tractor only) untill I put it in storage this fall, a month and 1/2 later. The AC still blew ice cold. I bet it works. Tell you more after seeding the crop next year. :)
