26-7 Fan Hub removal.

Post by Cigarboxrob » Sun May 17, 2020 9:29 am

...Howdy, Fellers and Gals!

After a lot of wiggle room, my fan hub sounds like a jackhammer. I ordered the sealed bearing hub from Snyder’s-Who had it to me in record time. Noting the nut on the back of the shaft, I can’t seem to figure out how to remove the pulley. A socket on the end just spins the internals. Any input would be appreciated! Thanks!

You have to take the fan off the pulley, there are flats on the shaft under it.
I know the voices aren't real but damn they have some good ideas! :shock:

....I’ll double check! It appears the only way to remove the fan is to remove the water neck from the block as a complete assembly as it’s just too close to the radiator to access those screws! I’d normally do that, but I don’t have a replacement gasket on hand and I’d like to drive the old girl today!

Dont forget to inspect the fan for cracks. The 27 I am working on for a friend had a crack that was painted over. I found it when I had the radiator out.

Unless it's rusted in place, you should be able to remove the eccentric from the rear, after you release the nut on the fan shaft.

Then the fan shaft with the fan should drop down and out through the slot in the bottom of the fan bracket. The longer fan pulley for the late thin row radiator complicates things.

Chances are the Fan Shaft is worn and the bearing hub will be a loose fit and it needs to be replaced as well. Also you might need a washer to compensate for the felt washer which is no longer needed. I found one of the correct ID, thickness and OD that fits inside the fan shaft cap.

Very likely easiest way would be to remove the radiator first. Then you can remove the blade and or remove as in the picture by Dan. You will need to remove the fan anyway to remove the shaft.

...Gentlemen, I thank you immensely!

...I’ve just sprayed the shaft with PB and tapped a few times. I’ll let that sit and stick a 3/8 on the shaft...I have a bin of washers somewhere in this mess of a garage, so I’m sure I’ll find one that fits. It looks like this can’t be done: “In-Car,” so I may just try the cereal box trick for a gasket!

I was meaning the gasket between the water outlet and head if you took it off. With the sealed bearings in the hub, you will not need a gasket between the hub and fan.
From Lang's catalog;
Fan hub ball bearing accessory pulley, All new, machined aluminum. 2 sealed ball bearings, No oiling or greasing required, no exchange required. Modified with modern style ball bearings. NOTE: Ball bearing fan hubs use permanently lubricated, sealed bearings. No more grease all over your engine and hood!

The gaskets you get from the suppliers may be a little thicker but are just plant fiber.

I know gaskets are cheap, but I like the idea if I am in a pinch. (And if I just need a gasket shipping can be expensive.)

I like to learn something every day. For those, like me, who never saw the ball peen gasket making here is a good example:

....So, I ordered a new fan shaft from Snyder’s....The two ball bearing job that’s sealed.

...Snyder’s cautioned me about the shaft; Sure enough, the new shaft won’t slide in. Too thick.

....Without a lathe, any suggestions how to turn the shaft to fit? Thanks in advance!

If you only need a few thousands off the new shaft, try sanding it down. Fit the threaded end into your power drill chuck, mount the drill in your vise jaws. Spin the shaft at good speed holding a folded over length of fine crocus cloth about 3/4" wide, several inches long to then pull it back and forth over the spinning shaft. Check often to test fit. Poor man's lathe :)

Before you or someone else does something, remember the shaft can be a tight fit into the sealed bearing hub. What is the OD of the shaft and IF of the Hub. Depending on the difference you may need to take to a local machine shop.

....Ready for this?

....After struggling and fighting with the “new” shaft, I took the old one, checked for bends under a laser, and “plonk!” It slid right in the new hub.

....Go figure.

....To anyone who’s ever done a ball bearing hub in a 26-7, what did you use as a spacer between the hub and shaft near the engine block fitting? I’m just trying to save a lot of trial and error! Thanks in advance!

Using the stock hub as example: I found a thrust washer the same size as the brass bushing (OD/ID) and was thick enough to cover the shaft end and fit inside the fan shaft cap. The purpose is to prevent the bearing bushing from spinning. True Value hardware stores with those multiple part trays will have them.
