Governor spring

[Mht]

The rod is 1/8 diameter. A long screwdriver through the loop end will allow you to use the screwdriver as a lever to wedge against something and pull down on to stretch the spring while allowing you to use your other hand to guide the spring into the hole. Cutting the spring to open the ends slightly as others have recommended is also a big help

Hi,
Below is a listing at TM Tractor for a new governor spring. It says it is a Case IH spring.

I don't know what the ends on the brand of spring you are using look like, maybe they are more closed is why you are having trouble putting it on.
It doesn't look like the Case IH spring needs any cutting at the ends, it looks like it might fall off if the ends were cut.

Glen, that’s the spring I had. Maybe I should’ve tried it as is first. I was worried about doing it with it being so hard to move my hands in there. I’ll try putting a spring on that is completely untouched first. I ordered two I case I mess up one again.

So after way too long and swearing way too much I feel like I should go to confession...but I finally got it on. I took fan/hub assembly off to have more room. I got a pair of 45° needle nose pliers and got it on. Now I need some advice for the fan hub. That gasket on the inside is rotted and is seeping oil so that needs to be replaced and I either need a part number or was hoping I could fix it without buying a new one? Thanks.

Hi,
Nice that you put the new spring on.

You didn't say quite where the fan assembly leaks.
If it leaks when you tip it to the rear, that is normal, there is no oil seal at the rear of the assembly. It works when in position without leaking much.

There are 2 gaskets in the fan assembly, the parts pics at TM Tractor show.
I don't know which, if any, gasket is leaking in your fan.
If none are leaking, they don't need replacing.

Below are listings for new gaskets.

I would use some sealer on the new gaskets, it might help keep them from seeping over time.

The shroud is originally a round shape. Someone has cut part of yours off, it looks like in the pic.
You can look at the pics of a new one below.

Since you have it apart, if the fan belt looks bad, TM Tractor has new Case IH belts, it says.

It's better to replace both belts at the same time. Below is the generator belt.
I guess the Cub is a 1952, if the serial number is 165152 or below it originally uses this belt.

While the fan is off is a good time to change it's oil, tip it with the rear down, and dump out the old oil, if you catch it in a clean drain pan, you can see what is in it.
Remove the oil screw, and put in some thin oil, I use a pump oil can. Be careful to not lose the rubber seal on the screw, sometimes it comes out with the screw, and sometimes it is stuck on the fan hub.
Just thread the screw through it if it is stuck on the hub.

Tip the fan different directions, then pour the oil out the rear of the fan.
When you put the fan on the Cub, be sure to oil it like the operator's manual says. It has to have the right oil level in it. It uses motor oil.

There were 2 different size generator pullies used over the years.
I can't see in your pic which you have. Sometimes people change parts and it is different than original.
Below are pics from TM Tractor of the 2 pullies on the fan hub.
A 1952 Cub originally had the smaller pulley. It uses the belt I posted above.
If it has been changed to the bigger pulley size, it uses a different generator belt.
Both use the same fan belt.

Hi,
I wrote the above post before reading your other post. The fan hub in your pic has the smaller generator drive pulley.

[Angelofbrz]

Thanks Glen. The generator belt is a little worn out.

Hi,
The operator's manual for the 1950 Cub, which has the smaller generator drive pulley on the fan hub, and uses the shorter belt says to take the belt on and off over the rear of the fan hub.
The belt is evidently too short to go over the fan blades.

If you are replacing the gen belt, you need to buy it, and put it on before putting the fan on again.

If the belt was out at the end of the adjustment, it is too long, and a new one should be the length so the top adjustment bolt is mostly in on the adjustment slot.

If you are buying a belt locally, you might need to buy more than 1, and fit the best length one on.
If there is a parts store where they know you, ask if you can return the unused belt or belts.
Sometimes I have to do that on other machines.

Remember the fan belt has to be adjusted to the right tension before the gen belt can be adjusted.
The Cub operator's manual shows the tension.
