I hate that type compressor as sitting on 100MPH plus and over taking having it growl a way to 5500RPM in 2ed overtaking, had to back off and hit the gas again so she would not rev so hard and explode, it got sure could get bloody cooled tho.
I remember taking my mum from Bundaberg to Brisbane and she freaked out about that noise, but did not mind me sitting over 100MPH for a lot of the way, she even made my mate sit in the back. Yes, the York compressor came either black or alloy (silver) finish, although the factory Ford Yorks were always black. Holden never used Yorks from the factory, because they had access to the better A6 unit which was made by an 'in-house' GM owned division (Frigidaire or Harrison, depending on the era). The York noise drama was more a problem caused by badly designed aftermarket mount kits, which had the belt run at odd lengths between pulleys. Sure it was exacerbated by the design deficiencies of the 2-cyl unit, but the factory Ford systems had well designed mount drives & were relatively noise & vibration free as long as the belt tension was correct. Chrysler Aust. used a similar compressor 2-cyl made by Tecumseh & it too suffered these dramas. The 'rotary' style compressors, like the GM A6 & the smaller Sankyo/Sanden compressors suffered far less from this issue, because of their multi-cylinder design. Dr Terry From what I remember the same type in my dads 1971 LTD Galaxie and the Falcon XD V8 type is the same that had a big heavy flywheel type thing on the belt end of the compressor and my HG compressor did not have that.

That's correct, when fitted to Ford V8s the factory-fitted York compressor often had the flywheel type clutch. It helped overcome the belt harmonics I was referring to. The aftermarket Yorks usually just had a plain twin-groove style clutch with no flywheel. Dr Terry Edited by user Monday, 16 January 2017 10:51:27 AM(UTC)
