Well, it bit me!

The procrastination, that is. When I rebuilt the engine on the '52 8N, the biggest problem in putting everything back together is the newer parts just don't fit just right. Case in point. Water Pump! New water pumps are too thick in the flange area that goes over the studs. Nuts won't go on but just a little. I finished putting the newly rebuilt oil pump back on and then the oil pan and closed her up. Surgery complete! I need to make sure this oil pump will hold the prime over night, as the last one I performed surgery on just went belly up! So I sent the pump off to a great forum member and got it returned shorts. Keeping my fingers crossed.

Oil in crankcase...check
Putting water in the radiator...check..Oh crap, where is the water running out from. Hoses connected. Clamps tight. check
Look under fan and there it is. Not just one, but two of the nuts had backed off due to not catching enough thread to really hold the water pump locked in place. I had a booboo when I lifted under the tractor and rolled the front end back into place for bolting the oil pan to the front axle. Hmmmm, just a little too high to line up, slowly let off jack handle pressure...oh #&*%,Too fast. Abort Abort mission! Dang it, came down on the blessed fan blade. I had to "coax" the blade back into the correct alignment so it would not hit the fan shroud. Bent it back by pulling on it rather hard. Seems good now. Started filling with water and that is when the "above" problem happened. Pouring out of the bottom of the water pump now. I guess pulling back on the blade was enough to break loose the seal on the bottom due to lack of thread for the nut to grasp completely. I got all ill with it then, and a little colorful language. Good thing the old red head is down at the beach with her girl friends this week. I still can't figure out how from 50 yards to the barn, if I hit something and let go a word or two or three, the window comes flying open and I hear her going, "I heard that!". She must have some king of an electronic device snooping on me down there. Ugh. Anyway, I dug out the old water pump which still feels tight and cleaned it up and put it on. The bottom stud is somewhat stripped thought. I'll try putting water back in tomorrow morning and maybe...just maybe it won't come pouring out. If it leaks, I will have to go get a stud puller to remove it. [b:715243768d] Does anyone know what size the studs are? [/b:715243768d] Heck, I might just use a bolt. This thing has done aggravated the you know what out of me. I think sometimes it's easy to spend way too much time fooling with something rather than just getting a tool and remove the offending member! On a side note, that red head is going to cut my tongue off if I "slip" and say one of those bad words and the grand kids are around...got to be careful. I'm ok until I get really stressed and disgusted with something...then look out. Sure glad the preacher lives a mile down the road...wouldn't be fittin' otherwise...lol :?
 

I could have swore I suggested Will Kellogg Automotive in Arizona to you.

For the simple reason that you would have gotten back your original water pump, restored with a whole new long lease on life.

Will Kellogg taught me over the phone how to restore my IHC water pump and sold me the bearing & shaft, mechanical seal and 2 gaskets for $17. !!!
There's a gasketed plate on the back of the pump, so the 2 gaskets. Great old heavy duty International water pump.

I am not doubting your experience. Just saying, I have replaced three water pumps in the last few years and not seen this issue. Must be
different vendors out there.

It could easily be different vendors. The one I bought a year ago had exactly this problem -- the flange was too thick. I had to buy a stud removal tool to get them out. I was lucky that the local O'Reilly's had exactly the studs I needed on the wall for cheap (they are intended to be used as carburetor studs).

This appears to be a common problem. Eric O. of South Main Auto Repair had the same problem with a Chrysler 2.7 litre V6 water pump replacement:

I think the Chinese making this stuff are not paying attention to the specs for the molds to produced them.
They just mass produce and good luck with them fitting properly.

I got the stud out and the pump on. No more leaks. I fired her up this morning and the oil pressure was good so I hope that is solved. I've about had enough of rebuilding what was already rebuilt on this thing. Time for a ride! :)

robably overly thick to have enough strength, being cast from an iron/dirt mix! :cry:
