Installing a Sanden compressor on a 617- looking at all options - PeachParts Mercedes-Benz Forum

My vote is to use an idler to tighten up the belt. It is a much better solution to have the compressor in a fixed position then having weak points with a swinging compressor. It would be great if you can make it work with the space limitations below.

I am leaning that way as well. However, there is very little room between the compressor pulley and the vacuum pump. Maybe an inch and a half. That just means that the belt will need to be just right, or a little on the short side. I may be able to find a smaller diameter pulley as well. However, this may all change tomorrow if I find I can relocate the PS pump down low, and the A/C up high......Rich

That would be terrific if a solution could be found for swapping positions.

Since you've got a free standing engine, can you take some reference pictures of the block particularly directly head on and directly from the side in the area that the compressor might go. That would help those of us who don't have such a platform to visualize a little better what we've got to work with on the block.

Post #3 has photos. If something more precise is needed, let me know.

Yes I know there is not much room, I thought about extending the compressor out to the side as much as I can and using a stand alone idler from a late eighties or early nineties Honda Accord similar to this but in a V-belt pulley.

Here's a reference picture of the front of an OM617

If I imagine a Sanden tucked in close mounted to the block, something like the following, I'm not seeing much of anything to tie an idler into.

That vacuum pump is kind of in the way. Just to kick off an exploration of options, would it be possible to block off the vacuum pump and go with an electrical pump and use the vacuum pump real estate to mount an idler?

Here are a few pictures of a Sanden compressor off a Euro 123 I came across a few years back. the last 3 pictures show the mounting holes in the none turbo engine just under the vacuum pump. the 617.952 engine oes not have these holes.

Charlie, that's what we need!! Where can we find brackets like that?
Mach4, Charlie posted some great photos of the engine. I need to figure out how to make a bracket out of steel that looks like the one Charlie saw.
