My old style grain elevator broke a sprocket. I have NO idea how to get it off and replace it. I have attached some pictures for advice.

Pic 1 First the elevator.

The sprocket is on the far right, this one is OK.

The PTO shaft, I thought would slide out after I took all the screws out of the sprockets.

Pic 2 This bearing is firmly holding the shaft. How does the shaft come out?

Pic 3 This looks like a bearing. But it is firmly attached.

Pic 4 This sprocket is cracked and will not tighten down to the shaft. I need this off the shaft.

Riptides,

It's not a fix but if you're needing the elevator now then could you put a couple of tack welds on the shaft/sprocket area until the off season? I'm not familiar with this type. Looks pretty seized up though.

In pic #2, it looks like the end of the shaft has been hammered al long time ago. Like maybe someone tried or succeeded in driving the shaft through the bearing?

It really looks so bound up you might consider rebuilding it. Can't be much left of the bearings. Don't see any grease zerks, probably sealed bearings.

I am assuming because you can get it apart, you can't take the shaft completely out and use a shop press on it?

Dave.

Yep, you would think it would slide off the bearing right? I used a whole can of wd40 on it. But those bearing will not budge off the shaft.

Yeah, considered that, since it is only used twice a year to move hay to the loft.
My issue is I needed it tonight, I got two hay wagons that need to be unloaded, and it started raining. OF COURSE.

Do you all agree that it should slide out, or do you think a set screw is holding the shaft somewhere else?

Thanks!

Just wondering but does that "bearing" spin freely, or is it bound up? You might consider taking a sawzall and just cut it off, being careful to cut the last little bit of it by hand with a hacksaw. That SHOULD at least get the bearing off, which looks like it needs to be replaced anyway. There should be enough left of it to take it to NAPA and get it matched up to a new one. After you get it off, you might see about taking the shaft to a machine shop to see if it can "cleaned up" some on a lathe. I doubt a new bearing would just slide right on the way it's been mangled up. Good luck with it.

Anybody close by your place sell elevators? Looks like you could use something a little newer:rolleyes:

Yes, the inner part spins freely, but it is frozen on the shaft.

Hey, twice a year. You price those new elevators? :) Plus, there is the old fashion way. Stack and lift! :)

I got it off.

So, is the bore standard on these sprockets?

What where they called originally? Grain elevators?

It has six teeth.

There is not enough material left to attach it back.

Should I get two? Replace them both?

WD-40, a railroad spike, and a sledge hammer are great tools! :)

I am calling TSC and AgriSupply shortly. I hope the bore is standard sizes.....

That looks like a hay elevator to me.

Soooo you're the reason it started raining here 3 days ago and has hardly quit!!:eek::D Get a load of hay on a truck or trailer, cut and laid down or even raked and here comes the rain! Actually, we needed it!:D

I agree with Gooseneck around here they're called hay elevators or conveyors. Could be a regional term. Heck our ponds are Texas' tanks!:D
