Anyway, since the whole setup is missing on the donor engine, I figured id see if you guys knew what was involved(i.e. other parts needed, etc.) in switching to the newer style and any pros/cons of doing so. Basically all that's on the donor is the spring mount at the top. There's no bolt or anything for the tension arm itself.

11-26-2013, 09:03 AM #1So I am contemplating swapping an om603 into my w123 but the one I'm looking at buying is missing a few things. Among them is the belt tensioner. I happen to have one I believe is for an om606 or newer om603 which I purchased on mistake when I was correcting that issue on my '87.

The 606 tensioner is pivoted on a see-saw arm one end of which has the spring which is itself anchored to a lever thingy which allows the tension to be released. Arrows show where the bolt goes when the tension is correct.

The opposite end of the mounting see-saw has a small shocker going up to that bolt in the head you see to the left.

It looks like the spring part is basically the same as the 603. I know when I tried to install the above part, something was different, I want to say the bolt wouldn't fit.
