Drive Belt Routing 1973 280SEL 4.5
I am looking for a drive belt routing diagram for my 1973 280SEL 4.5, (117.984 engine.)
I don't have the owner's manual, but I have the Chilton's Manuals from 1968-1973, (which doesn't have the diagram,) and the 1974-84, (which doesn't seem to have the right one in it. Any help would be greatly appreciated. |

I'm not sure if this is for you engine. This page from W126 CD for 116 and 117 engines:

Thanks myarmar.
One of my concerns was the double v-belt for the coolant pump. I was not sure if this was stock, but the diagram shows that it is correct. I had a couple of questions from the diagram: What is the secondary air injection pump for? Do you happen to know the length of this belt? This diagram has been a great help. Now I can get the rest of the belts and replace them all - as soon as I get the rest of those fan bolts off! |

No. My engine does not have the 'D' belt and associated pulley/pump.
Should I be worried about that, or is it just a variation of the engine? |

No, don't worry. Back in 1973 MB did not use it. Here is old post with the theory behind it from Steve Brotherton:

Whew!
It's just an emissions control measure that my car doesn't have. By the way, thanks for the part numbers. |
