I'm getting an om617A engine ready to swap in and as part of the prep I replaced the water pump. The fan pulley won't fit over the shaft of the pump. The interchange book listed 77-85 300Ds and 81-85 300SDs for this pump.

I guess what I'd like to know is if the pulley I have is an oddball, or if the new pump is. The pulley fit the old pump so a pump exists that fits this but I'm not sure where any of it came from on this engine.
