Alternative compressor and/or mount for the Euro w123 - Page 2 - PeachParts Mercedes-Benz Forum

The Sanden bracket that I spoke of was for mounting on the lower left where the later cars with an R4 have the compressor mounted.

If I had an early car with a York, I wouldn't swap it for a Sanden or any other compressor. The York is simple, cheap and more easily serviced. The service valves on these units are a God send.

The York does not hold up to the higher head pressures of a 134 conversion, but so what? R12 is now cheap and plentiful.

I have an old truck with a York or Tecumseh and it's great. I worked on LOTS of systems with these compressors in the old days and they are great and simple to work on. There's none of this flush everything so that you know you have the right amount of oil crap. You check the oil in the compressor with a home made dipstick.

These were fabulous systems. If you have one, don't wreck it by making an oil circulation system out of it.

Yes Larry, but your old truck probably has 300 hp....
It does require more HP to run the York .... and the Sanden will fit in a smaller space and spreads it lower HP requirement over many little tiny cylinders... a very smooth setup compared to the two York cylinders .

Are you saying that on the York with its sump oil capacity that no oil needs to be circulating through the top of the system ?

The R4 does not have any oil sump ..... but does that apply to the Sanden also ?

I know my year was the setup for the york compressor...but I have another non turbo engine that has the holes drilled in the block, its from a 79. I supposed I could make it work by drilling and tapping the hole but that would be kinda hard to fit an apprioate drill with the engine place.

the kit has got my interest since it will be cheaper and probaly better to use the sanden compressor in the big picture since I need a new reciever drier, condenser, seals.

Here are the sanden pic when I first came across it.

I have a few more to follow.

That's basically why I'm entertaining the conversion. The A/C has never worked on my present Mercedes, but I remember the old York compressor in my w115 280. It was icy cold, and never required service during the 2 years I owned the car....but. I remember the noise it made, which sounded sort of like someone had started a lawnmower under the hood. Even in the relatively powerful 280 there was enough HP drain that I had to compensate for it by constantly readjusting the accelerator. This was in the days of the 55mph speed limit, in a car choked with California Smog controls. The combination made freeway driving a chore.

My 240D has much better driveability, but half the HP of my 280 - so I imagine it would feel like throwing out a boat anchor each time the compressor engaged.

But on the bright side it was so cold that in San Diego the air coming out the vents actually formed FOG!

Since the compressor mound didn`t quite fit my extra engine, 617.952. i decided to go back to PNP and remount the compressor mount on the Euro engine and do some measurements to see where the differences are.

This is looking up from underneith looking up towards the vac pump.
there are 2 bolts that go into the front. the 617.952 doesn`t have these.

These are the brackets that mount the A/C hoses

charmalu · #24 08-21-2009, 06:23 PM

These are the brackets that mount the a/c hoses that run across the front of the valve cover. one mount attaches to the two bolts that hold the thermostat housing to the block.

on the left side the bracket mounts to the bolt for the fuel filter.

the last pic is the mount that bolts to the bottom of the power steering mount for the oil cooler hoses.

This bracket is mounted to the power sterering pump mount, and the
oil cooler lines attach on the bottom side.

that third pic show one of the two a/c lines cut off, than come down to the compressor.
the hose next to it is a pwr steering hose.

As one in your same situation.. four speed 240...
I suggest you install what I did on my Karman Ghia AC installation..
A normally ON switch at the gear shift lever on the left side level with your thumb... which allows you to disable the AC from stoplight start while shifting and getting up to speed... your hand and thumb are there anyway... very easy and will help you get out of other people's ' way '......LOL

Here are different angles of the oil cooler bracket.

Yeah, I guess it would be a shame to interrupt the whisper quietness of a 240D engine.

My first 240D had a York and I felt no power difference between Winter and Summer. I was, however, about as cold inside that car in the Summer as I was in the Winter.

charmalu thanks for all the photos. I have been thinking about using a modern compressor in my 240D. Its always nice to see what other have done to solve the problem.

Not to hijack this thread, but I've been collecting York brackets for fitting to my pair of 617.912 cars. Its reputation for "cold air" temps seems unsurpassed. Since the York 280 is still in production, typically used on Kenworth trucks, and relatively cheap at $220, I figured -- R12 and York -- is the way to go.

Other than its "opposed twin" low speed shake, and supposed "incompatibility" with R134, is there a reason NOT to use a new York? Wouldn't a new York have seal materials compatible with R134 anyway?
