Anyone have an old techumseh a/c compressor they are willing to cough up? pm me please. I guess a york would serve as well, but let me know what you have available.
No, I'm not trying to recondition an a/c system. Don't worry about the ozone.
i would check the wreckers and if no luck there try a h/d truck shop or wreaker. kenworth and other big truck builders where using york up to about 3/4 years ago. i have about 4-6 here at home i have aquired to use as air comp. for myself and freinds.
strange, up here in cold old canada i have not seen a york on a new truck for a while. different order sheets mabye, up here it's all gone to n/d or sanden on the heavy trucks, even the h/d equipment has gone this way.
I'm looking for an old two cylindar tecumseh to build an on board air compressor, not an a/c compressor. The tecumseh, rumor say's, is the better candidate for the job.
the real diff between a tech vs york is the york is a pot metal housing and the tech is cast iron. one bolts in place of the other in many applications. the york is also a twin cylinder , it was first used as a truck air brake comp. and then later on was used for a/c systems. there is a link on how to convert it to do what you want but i can not find it at this time.
The York style AC compressors in the commercial semi trucks have a longer stroke crank in them which equates to a higher cfm at the same rpms as our stock units.
All of the stock units I have ever taken apart have two cylinders as do the commercial semi truck units.
You may run into hose fitting issues and will need to swap the compressor heads in order to maintain your stock hoses and fittings. Also, it is a piece of cake to swap the electromagnet and pulley when needed because the crankshaft ends for all of them (York style compressors) are the same length and diameter. They also use the same pulley retainer bolt.
The York is certainly an option, but I have a fetish for cast iron. Pot metal just doesn't do it for me. I was planning on hitting the bone yards, but if someone had one I thought it might save a little time.
There are a number of web sites describing how to plumb them up. Here's one:
the ford units in the 70's were cast iron. so there is anohter option. but i found the cast iron retained way to much heat and caused excess moisture to form in the tank so i went with york and have had 2/3's less. th epump also does not get nearly as hot.
On the forums you can ask about aquiring NEW parts but we're not allowed to ask people about having old ones for sale.
FTE suggests using the classifieds for want ad's.
My apologies. Good discussion though. I never considered the consequences of a cast iron compressor retaining more heat. Truth be told, I'm sure I can find one at a local abused auto parts store (u-pick, et al) when I'm ready to get the project underway in a few months.
