1965 190D W110 Fan belts

[DrCherry]

I noticed that there are two fan belts listed in the pelicanparts catalog, one 10x875 and one 10x850. In the notes there's a "through engine #131060".

So if my number is larger that 131061, I get the 875?

You are correct. It should really say "to engine #131060". Did some research and what is odd is the number Pelican Parts lists for the earlier engine the Mercedes EPC lists for a M110 engine, which is a 6-cylinder gas. The EPC lists several belts for the OM621912 engine (190Dc), which I believe all had generators:

N007753 009504 up to engine 131060
005 997 83 92 from engine 131061, also up to engine 000438
N007753 009506 from engine 000439

For the OM621918 engine (200D), which I believe all had alternators:

000 997 71 92
or
004 997 08 92 (9.5mm x 930mm)

My engine number is 621912-10-170293

Where does that put me in the belt race? I'm guessing 875.

I would say that 875 would be the one from the serial number. Not sure why there are different belts.
