Hahn SNow Giant 24 Auger Issue

My machine may be old but she is a beast. I have just encountered my first issue. When plowing through some heavy snow the auger stopped rotating. I pulled the machine back from the snow to inspect and found nothing broken. I banged the bucket a little and wahlah!! It began to turn again. This occurred several times. When I put the machine away I felt the tension on the chain. It was quite loose. My question: is there a way to adjust the tension of the chain and is this the issue. Impeller works fine.

Thanks.

Check the sprockets if the machine has seen a lot of use. They wear out.

Do you have the manual?
There must be a way to adjust it?

But I do not think it is just a loose chain, unless it is so loose that it is jumping off the teeth. And if that was the case you should hear and see that.

I hate shoveling SNOW!

If there's a chain adjustment on a Hahn, I've never found it. I had one that I ended up installing an idler sprocket on.

Augers

Any chance there's broken shear bolts or the pulley is loose or missing a key?

I've not seen your machine so just some logical guesses (I hope).

Hahn Auger

The sheer pins are okay.

I don't hear any noise in terms of the chain being loose or coming off. The auger will turn when not in the snow (I know...what's up with that?!). This last storm was a wet and heavy snowfall. Hopefully that was it but I suspect otherwise. I do not have a manual. The on=line links to allegedly "free" manuals always ask for a credit card. Not sure how that's free or why they need a cc# for something that is allegedly free!!!

Thanks to all who have responded so far.

Does that sprocket you put on has a chain tightener setup too?
Or did you just install the idler sprocket somehow?
I never screwed around with one.

If the chain is that loose couldn't you just take a link out?

Now that I think about it, it would tighten up and loosen up because the rear axle had a slight bend to it, so the idler was put in to keep the chain tension on it. Dang, I forgot all about that!!!!

The machine looked pretty stupid because the idler arm would rise and fall as the machine went forward, but it ran fine. Never had a lot of luck with Hahns though. They were a really oddball design, almost a cross between a Snowbird and an AMF.

If your gears look ok and there isn't a tension adjustment it could be the chain has stretched and it's time for a new one. That or maybe taking out a link or taking out a link and adding a 1/2 link depending on how loose it is.
I would be checking the bushings the shafts the gears are on too as any play in those is going to show up in the chain too.

I like Hahns they are just so hard to find in any kind of decent shape in this area.

Make sure the windows are up before the snow plow goes by !!
