Jammed up?

Like possibly stuck in 2 gears at once?   Pull the shifter out and look inside. The shifter forks hole should look like a small rectangle when it's in the neutral position and both forks centered. One should ALWAYS be centered depending on gear selection. If both forks are off center it's in 2 gears at once and will Lock up.

You can use a large screw driver to move them if that's the case.

Original transmission would be a model 5091

Wallfish. Thanks for some info. I just tried exactly what you had suggested. The gear move very easily. Nothing jammed. The hi lo however is stuck in hi I bealive. The pulley on the outside of the transmission stopped moving while I was cutting grass. It now moves a little and slips once a revolution

Look for two items when you open it.

The shift fork for Hi-Lo could be broken...

Stray needle bearing rollers (needles) from a broken bearing that can damage gear teeth..... they may show up in the catch pan along with the oil when you drain the Unidrive.

Yes that'll work. 

 

There are several videos in our Transmission Section to help you. 

 

Be sure to have a good place to hold the transmission securely on a bench or work surface. 

 

 

 

 

Once you've got it open post more pics. We'll help you through whatever you need to do or replace. 

 

Parts are still readily available by placing an ad on our Wanted section or contacting one of the vendors here on Redsquare.

Good deal,   :woohoo:          sounds like you don't need to dive into the transmission.  The pulley has a set-screw and a square key locking it to the shaft. Sounds like the set-screw isn't tight and the key has broken or come out.

Exactly, sounds like a set screw or woodruff key for the pulley. :eusa-think:
