Re: Delenair system on vintage Jaguar

Still in production, sixty million units later. You have choices. Do an oil change & flush, replace the clutch coil & go again if you like. It holds vacuum so the shaft seal is hanging in there. You could change the shaft seal when you do the clutch. You could replace the compressor with a r...

Re: Ford AC Retrofit

The SD7H15 is 154.7 cc/rev But like any compressor, shaft speed matters: https://www.sanden.com/objects/SD7H15_Performance.pdf The York was 210 cc/rev. On a gasoline engine. Overdriven from the crank, on an engine with a cruising rpm above the diesel's redline. 75-79 F series trucks had big evaporat...

Re: Cleaning out an old A6

The A6 with the flange for mounting in the A5 mount is not common at all. Hang on to that for sure. Flushing the oil from the compressor can be done without opening it. https://www.autoacforum.com/messageview.cfm?catid=20&threadid=12050 With an A6, you will need to drain & refill the sump wh...

Re: Delenair system on vintage Jaguar

Just buy a fresh York, and put it back together right.

That SD505 is a tiny unit. 90 cc/rev ? maybe less. The York is 210 cc/rev. See the problem?

Re: Ford AC Retrofit

Verify the compressor RPM. With the diesel engine's narrow operating range, swapping engines & compressors can lead to a mismatch. A compressor that is too small or spinning too slowly will give poor cooling. The OEM compressor for your truck was a 210 cc/rev York type compressor. If you install...

Re: Cannot get compressor to engage

And the good old jumper wire kills another compressor. That little wire sells a lot of parts. No you get to guess how much of the compressor metal went down the discharge line as it ground to a stop. Your compressor is seized from a lack of lubrication return, Running when the system said it should ...

Re: gauge readings

A lot depends on what you find in the dryer.

If it has a pint of oil in it, then you may need to flush the system.

If it is bone dry, you need to look at the condenser.

Re: AC has a loud short bang at startup then cools normally

Well, 2 compressor, same tensioner. Same noise.

I hate to just throw parts at things, but given the price of a tensioner assembly (under 50 bucks) and the ease of replacement ...

Still sounding like the hydraulic tensioner leaks down over time when not in use. Once it is cycling it is ok.
