Is a fan housing needed???

I've never seen a fan housing on a Cub.
Was it an option or did the early ones (mine's a 1948) come with it?
The description says that it makes the cooling more efficient, which makes sense.
But is it worth it? Does it really help?

Besides the cost, getting it in there has to be a nuisance - behind the rad, over the fan!!
 
OK guys. Thanks again.
As a former mechanic I understand how a shroud works & can be helpful.
I just wasn't sure about the Cub.
BTW, am I right that I'll have to remove the rad to install it or will it slip over the fan blades?

You need to remove the radiator.
 
Well that's great. I really do not want to remove the rad at this point.
That's a winter project.
Thanks again.

and yes they are a royal pain---always in the way and they eat fingers for lunch!! lol!! thats the first thing that takes a bite out of your hand when you try to work on them!!
 
I'd suggestion putting a sealed bearing on the fan. I loath the original bearings, the one of my F100 siezed up on me shortly after I redid the tractor. The 100 and 200 have sealed bearings, I have the one for the Cub, just haven't installed it yet. Will probably do that later this fall.
 
Not to get too heavy into physics but the shroud acts like a Venturi that accelerates the air moving through the radiator for cooling. The shroud also acts as a barrier to dumb people who like to put these hands and fingers into a moving object.

So it has two benefits that shouldn’t be disregarded.

I have a Terramite backhoe with a Perkins engine. The engine mounts went on the PO, and the fan took out the shroud. I got it without a shroud. IT kept overheating. I thought it was the head gasket because that engine in that application is known for head gasket issues. I took it to a Perkins dealer, and it turned out the overheating was the missing shroud.

The IH accounts would not have left it in the assembly or made it an option if it was not necessary!

I understand the operation & benefit of the shroud & I'm looking for a decent used on now.
But, I smile at your naivety regarding the integrity of a manufacturer.
While 1948 was a different world than we are currently enjoying, I would not go so far as to say that a manufacturer would only include an accessory or assembly or part if it wasn't necessary.

Early on, batteries, starters, lights, TC and PTO were options to have a lower base price in the target market for the cub. If the shroud was not required, it would not have been there in 48. In 47 and 48 IH made 57K tractors plus the engines that went to other applications. That simple shroud had a cost plus the bolts plus the labor to install, plus the inventory carrying cost X 60,000. It would have been a real material number to IH if it were considered optional. It is not "integrity". It is the pressures of the marketplace and cost-benefit analysis.
