So I replaced my water pump on my M a few weeks ago with an aftermarket pump. Everything seems fine (this is actually the second pump, first one had a bad bearing), but for the life of me I can't seem to get it to quit leaking from the front of the pump. I have repeatedly tightened the nut and have added packing (yes I greased the grease zerks prior to adding antifreeze), but after every run you shut the tractor off and it sits for about 5 minutes and once the system had built up pressure it begins to leak. I think the frustrating part is the way they redesigned the way to tighten the nut causes you to have to take the end piece off the shaft as well as one of the studs.
My dad's theory is that the system just needs to "set" itself meaning as you run it over time it will blow out antifreeze through the overflow until the system equalizes itself pressure wise and seal up. He said Model T's were that way. I only have one other tractor with a pressurized cooling system with water pump and when we rebuilt it we had no problems (non IH brand). I guess I'm just a bit frustrated is all.
Oh well, I'll keep on and hope it seals up soon as I am taking it across the state of Nebraska in 3 weeks. Rant over... for now
