Vacuum diaphragm replacement ? - PeachParts Mercedes-Benz Forum

Ether · #1 05-09-2007, 02:38 PM

Has anyone used the replacement diaphragms from these guys?

http://www.autoluxmbz.com/

If so, what are your impressions?

Also, can someone tell me if my 80 300SD has the double or single diaphragm actuators?

Thanks

I bought similar ones from performance products years ago for my 240D, they worked great but I would reccommend doing ALL of them at once. I repaired the one actuator (two diaphragms were ripped) in one door and it worked good for a few weeks. I was constantly having to retest the system every few weeks to find new leaks that kept popping up, i.e. "weakest link in the chain" theory. Get enough to do all your door actuators.

and yes, you should have the old style ones.

What about the climate control flap actuators?

From the vacuum diagram, it would appear that only one of the 5 actuators (#42 in the diagram) http://handbook.w116.org/Climate%5C83-604.pdf is of the double diaphragm variety and therefore requiring both the top and bottom replacement units.

Is this a correct assumption?

oops. when you said double diaphragm, I immediatly thought door locks for whatever reason.

going off the diagram, 40, 41 and 43 are the single element types, 44 looks like it would be the older style heat shutoff valve found on the early 107's, based on that one, I think that it would have two diaphragms in it, but am unsure. 42 would be a double as well.

good link though, I was unaware that the a/c pod diaphragms were available seperatly.

No, you were correct, I'm going to replace the door lock pods as well.
Just trying to get a fix on what I need to order. Not sure if I order tops or bottoms for the single diaphragm units.
I'll give those guys at autoluxmbz call and see if they have some insight into what I need.

Gee, do you have a link to the same thing in the W123 flavor?

Well, that site and the owner actually no longer do business. When you call them, you get a message saying that they are no longer selling and all orders should go to Performance Analysis Inc in Tennessee. (owned by George Murphy)

I bought a bunch of vacuum diaphragms over the phone, and they are of excellent quality and well... work?
They were sent and delivered promptly and I would definitely order from them again.
(no, I am not affiliated with him, I'm just a satisfied customer)

Those will fit the 123's ACC pods. I bought some and put them in my wagon. Have been working for 2 years.

no longer even a message at that phone number, just disconnected. If anyone finds out where to buy now, post back, I'm very interested. Got an large handful of pods that could use diaphragm replacement.

Here's the info for Performance Analysis:
Performance Analysis Co.
1345 Oak Ridge Turnpike, Suite 258
Oak Ridge, TN 37830
865-482-9175
george_murphy@compuserve.com

They sell these pods as well as a lot of things that normally fail, some in improved versions.

I called the Autolux number this morning and got the message that George Murphy was handling the products.
Called him and placed an order.

I got some sunroof paste from him a few weeks ago. He appears to do business the right way! Good guy. I will do more business with him in the future....

arew264 · #13 06-21-2007, 01:39 AM

Yep, he'll talk to you about what you need, and he just moves the orders along. Haven't heard anything negative.

Ether · #14 06-24-2007, 10:56 PM

Received my order yesterday. Quick service!
