Drive chain question follow up.

I went to town today and bought 2040 chain just like
the one that I took off the grinder. When I got to
looking at it I realized that I wasn't quite sure how
the chain ran around the tensioner block.

I dug around and pulled out the manual. The side
auger was an option so I flip to the back. The
picture of the chain shows that it originally came
with REGULAR 40 CHAIN!!! Ugh. Now I have this
brand new chain I don't need and don't have
enough regular 40 in my box to get the job done.

So I put the 2040 on it. Who knows how long it ran
with that "wrong" chain. I've run it that way for
years. It will run for lots more with new chain. Now I
have left over 2040 that will never get used.
Something else for someone to buy when I'm dead.

For some reason this reminds me of the story of the wife who cut off the ends of the ham before roasting it.

Oh well, its just one of those "man things" don't bother with the manual or instructions until things get jammed up. lol gobble

She did it 'cause her Mama did it that way and Mama did it that way because it would'nt fit in the roaster

well i said it needs #40 chain with those sprockets. that chain you got uses the cast sprockets with wide teeth. and i also said someone must have put the wrong chain on , and just kept doing that.

I worked at a sprocket shop for a number of years, and we made plenty of 2040 sprockets that were steel. Same plate thickness, same everything, except for the actual tooth. True there are cast sprockets and most of the time they are a 20xx pitch, but they're are also steel ones that use the same chain as the cast ones.

The cast sprockets, all that I've seen in that type, all still had to have the teeth machined on them in a gear hobb. 2040 will be fine, but next time I guess I'd probably switch it over to 40 pitch myself just because that's what's right.

Would a new 2040 chain running on 40 sprockets behave like a worn or stretched 40 chain, wearing 40 sprockets much faster than a new 40 chain would? It may not matter in this instance, but I would check the sprockets for excessive wear, especially the smaller sprockets.

Don-Wi · Sep 20, 2015

It should have absolutely no impact on wear of the sprockets, unless it's stretched, just like normal #40 chain or any other size would wear a sprocket faster if it's stretched.

If any one ever thinks they just need to remove a link when a chain has a little wear, it's time to replace. Machines have enough adjustment on the tensioners that when you run out of adjustment, it's time for new. I rarely let a chain get that far off I can help it. My dad on the other hand..... He's better now than he used to be...

i don't think either chain makes a difference running on sprocket for wear, but a lot depends on chain tension and load. anytime the sprockets and chain get excessively worn you can see the chain climbing the sprocket. just replacing one or the other don't work. both should be replaced as a set once the sprocket is worn excessively.

Yea she did it for years and her daughters did it too till one day when she was MUCH older at a dinner one of the daughters asked. "why did you cut off the ends"? Well mom looked at her and laughed. "That was the only way it would fit in the little pot I had"
