Gen. II-616/ 617 Sanden style A/C Compressor Mounting Kit For Sale + Install Inst. - Page 5 - PeachParts Mercedes-Benz Forum

I figured I would take some more photos and post some tips on installing this kit. I have found that it is easier to install the oil cooler line bracket BEFORE installing the compressor:

It is also best to put the rear most compressor mounting bolt through the hole in the mounting tab BEFORE installing the plate on the engine. You will need to remove the lower forward of the two mounting bolts to insert the compressor bolt, if you forget this step (been there, done that).

):

Another helpful tip: a 14mm wrench will hold the 9/16 nut tight while holding it up between the compressor (swung toward the frame) and plate to get it started (sorry no photo). Another thing I learned, is that the crank pulley must be smaller on the N/A, as I had to use a 15360 belt (15370 for a turbo). I have also found that the N/A takes a longer low side to compressor hose than a turbo, and has 90 degree fittings on both ends:

It will mount using longer bolts in 3 of the pan bolt holes, and nuts on the top. Another hole (1/2") is drilled in the compressor mounting plate .625 from each edge. Here is a look at the prototype:

Location of drilled hole:

The bracket is needed more for the 616 application, but I have prototypes made for both the 616 & 617 turbo (they are different). I am not sure if the 617 N/A has the same lower pan as the turbo. If it is different, I will need to make a third bracket. From now on, all of the plates will have the hole drilled in them, and the bracket should be available shortly. If you have a plate already installed, it is possible to drill the hole without removing the compressor. I will post here when the brackets are available, and send them to those that have already purchased a kit....Rich

I finally got all the brackets made (along with the parts for 30 more kits), and have them ready to send for plating:

When I get them back, I will make up the kits and have them available (I will start a new thread).....Rich

I went to the fab shop today to pick up the rest of the parts (plates and tabs). I snatched a photo of the last of the plates being cut:

The new design incorporates slots in the plate so the tabs are welded on the back (photo posted when I get one ready). I am calling it Gen 2.1....Rich

It's cool to see the pic of the manufacturing process!

BTW, I have not been able to get the 36" belt to slip onto the pulleys on my N/A. It seems like I don't have enough slack in the hoses to push the compressor flush with the mounting plate. (Mine was the pilot for the longer Low pressure hose). I have a 36.5" on right now, and it works, but the adjustment bolt is screwed into the collar almost all the way to the head, and I have to retighten it about every week or two.

I have a nut on either side of the collar to try and help lock it in place, but it hasn't worked.

I think if I could get the shorter belt on it would be less likely to need so much readjustment because the adjustment bolt would be spanning a shorter distance from the collar to the mounting plate stop.

One thing you might consider is tapping out the place where the adjustment bolt hits the mounting plate (maybe not all the way through the plate), just to prevent the end from slipping around where it contacts the mounting plate.

I should have the new plate braces today, and that should fix your belt slipping problem (provided you are able to get a shorter belt on there). I will be providing them in the new kits, and also will send one to each of the buyers of previous kits (Gen 2 only). The brace will not work with the Gen 1 plate without welding it on (with the plate installed), and also not without some additional fabrication. Photos will be posted in another thread when the braces are ready to be distributed......Rich

Rich,

Why was the PF condenser oriented with hose connections placed on the passenger side? Was there not enough room to route them more directly to the compressor & dryer on the driver's side (and thus without crossing over the engine)?
[QUOTE=ROLLGUY;3150684]I just got finished installing a parallel flow condenser and hose kit in my neighbors 300D. The 16X20 parallel flow condenser was purchased on ebay motors.

The rest of the hoses and compressor:

On a 123, the factory condenser connections are on the passenger side.
I could have put them on the other side, but I would have had to run the hose from the condenser to the drier from one side to the other. If I remounted the drier on the other side, I would have to run the high pressure hose (thin blue) to the driver side. So either way, a hose will need to cross from one side to the other. Fortunately for you and anyone else with a 126, everything is on the driver side (condenser connections, drier, compressor, evaporator connections).

great work. will this kit work on a 1990 560 sec ? i just bought one and i live in Saudi Arabia "AKA middle of the Arabian desert" and in the summer it get really hot here. ~45c in noon, 30-35c in the night.

so obviously i need a good air con to be able to use the car in the summer, do you have a solution for me?

This kit is only for the Diesels that had the GM R4 from the factory. Your car has a Sanden style compressor (at least US models did) from the factory. If your car did not have factory installed A/C, then you are in for a LOT of work. If it does have A/C, but not working, your local repair facility should be able to fix it.....Rich

.....just to give you a idea how much LOT he is talking about

osama · #71 02-05-2014, 12:33 AM

WOW

luckily the car is equipped with a/c already. and its cooling to an acceptable degree for the current weather conditions, im pretty sure though that it wont be enough for the scorching sun of the summer in this part of the world, i think Texas weather is the closest to what we have here

summer temperatures are around 115 degrees (45c) , and the air is 100% dry , no humidity at all.

i just bought the car and i thought if there is anything i can do to make the air conditioning more effective , it would be better to do it now than in the summer.

i will pop the hood and post some info on the parts i have.

On the parallel flow condensers, what size fitting should I be looking for? The one I saw on ebay had #6 and #8, is that correct for a w123?

Yes correct. It should be a 16" X 20"......Rich

I spoke to you a while back before I blew my engine.

I have a Sanden 4704 that I bought new for another long ago project. I believe you said it will work with your bracket, is that correct? I did change the head as per your suggestion.

I want to order your kit soon but I need to do an inventory on any hoses and other items I might need. If I spend this much, I might as well get all new parts.

I'm in Chicago and its 18 deg. so thinking about air conditioning is a little hard for me right now.

All you would need is the bracket kit, drier, and hose kit. If you decide to go with a PF condenser, you would need an additional hose ($20).....Rich
