Thread: Yorrk Compressor modification

Its somewhile since Ive played with the York's. One important thing I do remember is that there are Left and Right handed models. That is, one is designed to lay to one side, the other is designed to lay to the other. Note that the oil mod you make allows them to be laid further over, but not recommended at 90 degrees.

Somewhere I have the service manual's for them. I'll see if I can dig it out of the archives!

I downloaded a file called 2CylinderServiceManual.pdf from the net, it's suppose to be for the York.

Page 6 shows 90 degree orientation in either direction.

Page 5 has descriptions for the "True Universal Mount" and "Universal Rotation" of the unit.

On page 4 there is a reference to "Left hand" and "Right hand" suction identification on the ID plate, I looked on top of the unit, one side is printed "suction" the other "Discharge".

If your manual has some more up to date info that would be appreciated, when I can I'll get another grub screw, I won't have time to pull out the compressor and have a good look until the 26th at the earliest.

Update ... I pulled off the back cover and base plate from the York compressor, no luck.

Next I removed the top cover which has chambers and channels to direct air to the correct outlet, the plate directly under the top cover came off next, this plate has holes in particular spots to direct air to the correct top cover chamber, I removed the 2 locating pins from the plate and turned the plate and top cover 180 degrees and re-assembled the compressor.

In the next couple of days I shall start the Rangie and test the compressor to find if I now have a left tilt compressor ... I keep you informed.

why not mount in vertical position i have used a york in the vertical position for over thirty years with no problems block off internal oil way it pumps very little oil at all also let the sump breath run air into a tank

As I already have the main alternator with oil pump, 2nd alternator electrically isolated for the additional battery (both batteries are connected in series to run our 24 volt Warn high mount winch) lastly the air conditioning compressor on the bottom there was no room on the left side of the motor, the York is on the right side tight up against the motor above the injector pump so the belt misses the power steering which is bolted to the front plate of the motor, if the York is vertical the bonnet won't close.

I know I could use a serpentine belt to give me more positions to mount the York ... Nah, not interested in changing everything over.

Almost forgot .. there is already a large air tank that takes up most of the space under the driver's and rear passener's floor.

Glen I think at 90* the oil is being sucked past the rings on the lower cylinder, i have tried to solve this by installing extra ring on piston but not successful hence i went vertical may be get it up around 40-45* so the sump oil is not flowing into lower bore ie only being splash fed by crank in oil. At 90* it is a similar problem as the rotary type comp am at present playing with a rotary filled with grease on an other vehicle no definate results yet

Interesting ... looking from the bottom with the lower plate both pistons didn't look that different.

I have been working on the boat Today fitting a HD television, 2000W inverter, new fish finder and marine VHF antenna base, so many wires .... ran out of time finishing off in the Rangies engine bay. Maybe Tommorrow, I'll post how the compressor goes when I do get to go for a drive.
