In the middle of the retrofit of a Sanden compressor in place of the old York compressor. Just thought some people here might be interested.

York in car:

Car without the York:

York and bracket:

Bottom bolts on York/bracket:

Will keep posting linked photos of this retrofit.

So do you got to go with a different bracket or modify this one?

The kit includes an adapter plate for the Sanden. Since the Sanden is so much smaller, the plate appears to only use the four bolts on the vertical part of the bracket and not the bottom two.

Im not sure how much the old york tapps, but the radials eat 15 hp---ide bet the york eats more.
the sanden eats 7hp

I read somewhere that the york eats 19hp...

Great pictures. Thanks for posting them.

You staying with R12 or converting?

Very nice. I will be following this thread.

Graplr · #8 05-01-2012, 09:23 PM

Interested as well. Did the York compressor quit? Or are you just upgrading?

Sticking with R12, since I found a shop that still works with it.

I used the sanden to york bracket when I retrofitted a sanden in place of my R4. I mounted it differently because my compressor is on the bottom of my engine.

Just so you'll know, the bracket I received was pretty crappy. The "arms" for adjustment were out of square with the base and the slots were cast wonky. You may have to do some work on it to get the compressor mounted square. It eventually worked but just not out of the box.

It came with a bunch of bolts for mounting the compressor but I doubt it would have stayed in place and held belt tension if you used it the way prescribed...

Just a FYI, a sanden 709 compressor uses the same mounting locations as a 508 and is a newer 7 cyl (VS 5 cyl) design. I'm happy with my 709 in my 116.

The York had given up its ghost. There was no pressure on the high side anymore. I will likely rebuild the York and sell it. I just figured that while going through the trouble dealing with the A/C system, I would to the conversion to a Sanden as well.

I've also found that most of the firewall grommets have rotted and shrank over the years. This has contributed to the funkyness of the interior smell for sure. The most expensive grommet yet is the A/C line grommet A123 997 12 81 at around $50.

I've had so many obstacles with the family thrown in my way that this is an, hour-at-a-time job. I have to steal just a few minutes here and there to take shots of the work, and keep the project going.

I will try to roll the car out to the driveway to degrease the front lower half and the rest of the engine bay.

I will have to hook up the battey and run it for about a half a minute to pull it back into the garage. Should be fine without a fan, water, radiator for less than a minute of run time.

Wish there had been an easy way to swap a Sanden for the R4 on my 240D.

Happy Motoring, Mark

Thanks for the tips. I will be test fitting the bracket tonight and probably painting the York bracket to prevent any rust.

Hopefully I will get the lower front of the car degreased by this weekend so that I can put most of it back together. The motor is really well insulated with 1/4 to 1.5 inches of gunk. I'm trying to make sure that I will be able to ID and stop leaks in the future. Plus, this will let the motor metal/air heat transfer work a bit better.
