Water pump/fan replacement....need some quick help, please.

Kenster · Oct 17, 2012

I'm in the process of replacing the water pump on my 52 8N. First time to try this. Going slow and methodical. Took the hood off. I can't imagine trying to do this in the tight, dark quarters with the hood on all squatted down and bent over and under.

So, I got the alternator out of the way and the hoses removed. I begin to remove the bolts holding the fan assembly on. Got three bolts off. The fourth one, however, is rounded off. No way that thing is coming off. I was able to get the pump unbolted and removed the whole thing with the fan still attached.

The fan is really in poor shape so I think I may as well replace it while I'm at it and not sweat the time and effort to do surgery on that rounded out bolt.

So, my question is.... Should I go back with a standard four blade fan or upgrade to a six blade?

Are all six blade fans "pushers?" My understanding is that a pusher blade moves air from the engine compartment and blows it into the radiator, rather than pulling it from the front of the tractor into the radiator. Seems like a pusher is blowing hot air from the engine into the radiator.

If it matters, I live in south Central Texas and it gets very hot here. I'd like to run into town to the New Holland Dealer or Tractor Supply and get this part today and get 'er done.

Thanks for your help.

oing to the store will probably make you decision easy, as I will be surprised it you walk out with a pusher fan, as in NLA most likely.

Thanks for the fast reply JMOR. My local (as in 16 miles away) New Holland Dealer did not have any in stock but can have one in a couple of days for me so I just order it. Tractor Supply doesn't have them. Four Blade. I might have gone with a six if one was readily available, but it wasn't.

I hate to get in the middle of a project and have to come to a screeching halt while waiting for another part, but so be it.

My fear now is that once I get it all reassembled I can't run a leak test until the hood is back in place and the fuel lines are connected again. If there is a leak I'll have to pretty much start all over. Oh, well....

This water pump/fan job and replacing the starter is pretty much the biggest repairs I've had to do in over six years of owning this tractor so I can't really complain.

Cheers!

here are about as many ways as there are tractor owners to rig a temporary fuel supply to run it a few minutes. Some get a bit elaborate, but I have cut a hole in a soda pop bottle, inserted gas hose (hole sized for tight fit) and connected to carb. Just a 16 oz bottle will run it for about 8 minutes.
Some use an old lawn mower gas tank & others use whatever container they have emptied lately. :lol:

I use a 2 gal lawnmower tank which runs an hour or so. I always run a rebuilt this way for a while. It make repairs and adjustment easier before you put the sheet metal on.

Just finished up with r/r-ing the radiator, water pump, fan, and coil after the water pump let go allowing the fan to munch the radiator. Worried about leaks myself, but went ahead and put everything back in place to test. I like living on the edge :mrgreen: ! Ran it up to operating temp and open thermostat, no problems. Button 'er up snug and check everything over, you'll probably be just fine. Mark
