Front PTO alignment problem
 

I was hooking up a QA-42a snow thrower to my 106 last night and I noticed that the front pto on the engine is really offset compared to the hole in the frame under it for the belt to pass through. I had the thrower on it last year and didn't notice this but this year I see the belt is almost hitting the frame and I cant adjust the pulley on the thrower gear box to line up with the pto because that would cause the belt to hit the frame. I did have the engine un-bolted and slid forward this spring so I could add a creeper gear (and again to remove the creeper, change the seals in it and replace the driveshaft:bash2:) I would like to think I bolted the engine back in correctly, but because of this and the fact I had to do some major tweaking on the mule drive for the mower deck this spring has got me wondering (idler pulley brackets were really wore out so I cut the rod they pivot on, drilled the holes on the brackets out, welded in some sleeves and put it back together. thought maybe something wasn't quite right when I put it back together.) it kept throwing and rolling the belt for the mower. I know the snow thrower was on a 1250 before I bought it so I had to move the 2 mounting brackets closer together to make it fit the 106. something just seems off but it could just be me. any ideas would be greatly appreciated.

Did you look to see if the motor was still bolted in? That's about the only thing that can make it that far out of line.

A QA42A uses spacers on the lower mount to line it up better on the NF tractors.
Somewhere there is a thread on this.

yeah the motor is solid, was thinking maybe there might be 2 sets of mounting holes on the engine or something. As for the spacers, if they are the ones I'm thinking about, they only center the thrower to the mount that holds the gear box.

I think Lew is thinking of this thread: http://www.onlycubcadets.net/forum/s...owthrower+belt

By the way, your PTO looks like it's falling apart.....something to look at.

That finger is out of position and it looks like it needs adjustment ( too far out )

Good eye Billy :beerchug:

Agreed, darn good eye. I replaced the center wear button this past spring, maybe I didn't adjust it right or something

Maybe it just slipped out of alignment. Getting the two jam nuts tight against each other can be challenging.

definitely looks like the same problem I'm having but going by the one pic of the install manual on page 2 mine is the right side and his is the left side.

How does your clutch basket / pulley line up with your starter generator? If it's too far forward on the crankshaft, you'd see the pulleys not aligning, and causing the belt to wear unevenly on one side. It would also create the problem you're suggesting.

I don't know that all the narrow frames are like this, but my PTO clutch had a snap ring inside the hub that you bottomed out against the crankshaft. i had my crank basket too far forward to where the clutch would bottom out on the fingers on the disk before the crank would bottom out against that snap ring.
