Fan hub on 1950 cub
Restoring a 1950 cub and I disabled the fan hub. Instead of a oil retaining screw it has a grease zero and when disassembled it eas full of axle grease. Also there is no stand pipe inside. Question is where there some models with zeros and used grease instead of oil?

Re: Fan hub on 1950 cub
looks like the ones that sells new now has upgraded sealed bearings. could this be a earlier replacement that didn't have sealed bearing and needed grease? im just grabbing at straws here but it sound good anyway

Re: Fan hub on 1950 cub
Hi,
I don't remember reading about fans that use grease on here. Does it look like a factory made part, or has someone changed a fan that uses oil to what you have.
I don't see how grease would work with the original style fan hub, grease couldn't get in where the shaft and bearing run.
Below is a page from the Cub parts manual. Number 7 turns on number 2, in the pic, solid grease can't get into the long bearing. The spiral part, number 8 in the pic, directs oil into the bushing.

Re: Fan hub on 1950 cub
The original fan uses 30 wt oil for lubrication. There is a slinger built in that may not distribute grease properly. I would take the fan apart, not difficult, and clean out the grease and replace with a low viscosity oil. Tap the screw hole, if necessary, and put in a matching screw with o ring.

Re: Fan hub on 1950 cub
Some of the larger tractors used a zerk on the fan (H, M, and 3/400). It is possible it could be like someone else said, and made that way. Then again, it might be home made. If there is any slack in it at all, I would change it out for a new or good used one. If not, clean it out and and put new gun grease in it, the old thin black type would be best. That way it'll run a little when it gets hot. YMMV, of course.

Re: Fan hub on 1950 cub
Hi,
rockfarmer, he said his fan hub has no standpipe, the standpipe is needed to fill the hub to the right level with oil.
Below is a page from the 1955 Cub owner's manual showing the standpipe, and lubing the fan hub.
Lubing the fan is a good thing to do in the Spring, before using the Cub for the rest of the year.

The 1950 Cub owner's manual says lube the fan hub every 60 hours of use. The pic was better in the 1955 manual. I don't know why they changed the number of hours for lubing it.

Re: Fan hub on 1950 cub
Thanks for all the info. I'm wondering if I should try to refurbish this one and cross my fingers or should I bite the bullet and buy a new one with sealed bearings. Has anyone used the new ones and has had good luck with them?

I just installed a new fan assembly in mine last week. I had ordered it before I had actually checked my old fan, and found it to actually be fine, just loose on the bracket. But, due to the new fan having sealed bearings and a larger pulley to drive the alternator I was putting on, I elected to go ahead and change them out. I found that it takes a thin 7/8ths wrench to tighten the fan shaft against the mount and I had to modify a wrench in order to do so. So far, I have had good luck with the new assembly staying tight, but I've only run the Cub around the yard a little since doing the 12v conversion and getting the new manifold on. The new fan cost me $83 vs. about $55 for a good used one. Being as how I work my Cub pretty hard, I bit the bullet and used new parts rather than used to (hopefully) avoid any future misfortunes that can happen when used parts are installed. Not saying it happens all the time, just that it can. But, for $28 more, why take the chance?
