Toro 624 power shift

Hello
i recently purchased a used 624 power shift.
The problem i am having and hoping someone here has a fix for is:
the dischrge cute will not turn as the two universal gears at the end of the rods do not contact each other all the time.

It appears to me that the rod that has the worm gear attached to it does not go back far enough to have the gear from the handle contact it.

I am not sure if the worm gear gets worn, and this casues the play that allows the rod to slip away from the other gear coming down from the handle, or what. After looking at parts manuals online it looks like all the parts are there, and shockingly i could not find any info out there on a fix for this issue ( hard to believe that i am onlyh one ).

Thanks in advance for any help or suggestions yoiu may have........

The gears may be worn to the point of no return. check to see if that 5/16 nut is tight. if you can post a video so I can see what's going on. ALOHA to the forms. let me know..

Long LIVE THE POWERSHIFT!! MAY IT NEVER RUST IN PEACE!!

Yea, I would check the adjustment of where the gear meats the chute. There should be a nut under it that lets you control how close the 2 gears are. If the problem is in the rods make sure none of the pins holding them together are sheared.

Please direct all snow blower questions to the forums and not to me with PMs.

So I cant get a video to upload...what is happening is the horizontal rod with the gear on it slides back and the gear attached to the vertical rod loses contact.
The only adjustment on the bracket with the worm gear is lateral to ensure contact with the teeth on the chute...no adjustment back and forth.

I can drill another hole in the bracket or cut the rod (I have been unable to remove the roll pin that holds the gear on the end of the rod). However this seems like it must be a common problem...is it just wearing of the gears. ..nothing looks to be bent....just that the gears lose contact due to movement in the rod...horizontal one I believe....

That is a bit different than how Ariens does it. If that horizontal rod is sliding it looks as though maybe the pin holding the rod to the worm gear at the chute is missing? Either that or the nut under it is loose and the gear is pulling itself forward instead of pulling the chute around.
