Welding/ building up a sprocket on spreader?

ryanwheelock · Apr 24, 2015

Have any of you guys welded/ built up the teeth on a sprocket before? I have a old IH 200 spreader that the chain is starting to skip a bit on the main sprocket. I'm thinking of building the teeth up a bit my on welder instead of hunting down a new one. Have had a hard time finding parts in my area for this spreader but haven't looked for this sprocket. Figured a hour or so and I could weld and grind it up enough to work again, doesn't get used a lot.

I've never done it on a small sprocket like that but did a bunch of them on crawlers and excavators back in the day. Don't over build them and leave your chain a little looser.
It worked good.

Is it cast steel or machined steel. You probably already know what type of rod to use for each.

Tell us which sprocket it is----Might be able to help

Its the sprocket that runs off the axle to turn the chain.

You might try replacing the chain first. They stretch and can give you a fit.....

I haven't looked that close at it yet. It was last summer when it started slipping so I parked it and used a diff spreader. Time to start moving manure soon here so want to have that one back up and running. Either way I know how to weld both cast and machined steel. Just wondered if its worth the time and if anyone has ran into problems doing something like this before.

I'd place the blame on the chain before the sprocket, although a bad chain will make a bad sprocket really quick.

I may replace roller chains more often than necessary, but $35 worth of chain is easier to replace than some $300 sprockets.

I agree with check your chain for stretch first. They are usually the first thing to go bad and the least expensive item to replace. Over 1 percent stretch will cause chain skip and rapidly wear sprockets. I have much better results running a new chain on worn sprockets than a worn chain on new sprockets.

That sprocket should be about 2-2.5' in diameter so I do not call it a little sprocker. Dought a new one would even be avaible.

What make/ brand spreader? Can you post a picture of sprocket? I have a couple out back just waiting to be called up!

I have built up chain drive sprockets a number of times. It works well. Weld up each tooth equally to the others. Don't try to build them all the way up to original size. Keep the profile of the tooth the same as it was new and you will be fine.
