Water Pump Replacement

I noticed the fan belt was a bit loose. When I looked closer, I realized the water pump was leaking. The new one is on order and will arrive early this week.

The question is, which is more work -- changing the pump with or without taking the hood off? Is it even possible to do it with the hood on?
 
It's tight with the hood on, but doable.
Taking the hood off doesn't really gain you much except vision.
The radiator is still the same distance away unless you remove it too.
Then you might as well clean it up and paint it and....... LOL
 
As Royse said...it's doable w/ the hood on. But it's usually a PITA.

Check out tip # 12.

And do not operate the tractor w/ a loose fan.

The picture is what happens when the fan comes loose.

Royse, you might want to tell him... With the hood removed and the coolant drained (or LEAKED) another 5 minutes will get the radiator safely out of the way to do a thorough removal of the water pump, and easy cleaning of the front block surface, and re-installation of the water pump.

Might as well "chase" the threads, as well.

And NO buggered up radiator fins.
 
You make a good point Bob, it is only two hoses and two nuts
to remove the radiator once the hood and gas tank are off.

If the hood bolts twist off or the carriage bolts in the bottom
of the radiator twist out, or the sediment bowl fuel valve doesn't
shut off and it leaks fuel all over, it can get a bit more interesting.
All of these should have been fixed anyway, but they all
happened to me at one point or another.

I've done it both ways and you are right, it is much easier access
with the hood and radiator off. However if I just needed it to get
back to work I would change it with the hood in place.

I use a 90 degree angle die grinder with a Roloc bristle disc to
clean the front of the block. Cleans it up in a jiffy.

Here's a demo of the disc I'm talking about for folks who haven't
seen them. They're spendy, but they work very well. BTW, they
are NOT left hand thread and eye protection would be good. Roloc

I did sense that mission creep was very possible if I took the hood off. It would be so easy to decide to paint the hood as long as it was off. And then might as well do the fenders since I had the paint ready to go. And since it's a 2N, might as well do the cast parts since they are supposed to be the same color. And if I'm painting it, how about that new wiring harness and plug wire set. etc. etc. etc.

Right now, I need it back to mow with. I think I'll try it without removing the hood. Thanks to all for the input.

So far the pump just leaks -- the fan doesn't wobble at all. I figured I'd change it before it came loose and ate the radiator.
 
I have changed them on 8n's with the hood on. It can
be done. I loosen and raise the front of the hood as
high as I can get it.
