I vaguely remember reading a post where someone did the exact same thing on a K46. IIRC there's something in the trans that you installed backwards.

See attached picture and part #36 says "note orientation when installing". I think that's it but you can call Tuff-Torq tech support to be sure.

justalurker... I think you nailed it. If that part went in upside-down it could change the direction.

That is better and faster help than I imagined I could get.

Thank you very much!

You are welcome.

justalurker, I wanted to confirm that you were right. I took it apart again, reversed part #36, reassembled and re-installed....

That fixed it!

Once again, thank you for the very quick and accurate diagnosis.

Glad to help...

Hi, Finished rebuilding my Husqvarna K-46 hydro. Was easy, seemed to be fine. Re-installed. Tractor goes backward. Did this a couple of times to see if I made a mistake. Took my John Deere K-46 and installed it - it also ran backwards which again, made me think I did something wrong. Just read on the forum that some K-46 need to have the wedge placed upside down to run correctly. I am going to try that. (Unfortunately, I did not take pictures of the inside of the trans. first.; just outside). I saw an advertisement about a video for sale regarding the K-46 rebuild and noted that his picture of his K-46 had the wedge, narrow side up. Maybe it IS possible that mine is upside down! Will try this, hoping that this is the fix. My repair skills are being challenged ! ha ha. Is it possible that John Deere has the wedge reversed from the Husqvarna although they are the same hydros ? Need some help here before I re-install for the third time.

Trust us - you need to reverse the Wedge and all will be well. Yes different makes have the wedge in different positions - all depends on how they run their linkages.

Thanks Leafeanator. I trust by reversing, you mean upside down Thanks again. Will let you know what happens.

I haven't taken mine apart yet but doesn't the wedge part have a wear surface from the pump? If so it should indicate at least how one side goes in. All I have ever read is put it in 180 degrees different.?? Probably only fits 2 ways.

It can go upside down, and the tabs are on both, top and bottom that allow it to set in place, but not simply turned around 180. The faces don't allow it on mine. I tried it upside down and it did fit correctly, but I didn't want to put it back together until I had some more input. I still don't see how it affects the forward -reverse but I'm going to try it.

Leafeanator, I turned the wedge upside down and it works great. It appears the John Deere and Husqvarna's foot pedals are reversed. Not sure how the inverting works, but it does. Thanks again.

I think Tuff Torq calls it magic:)

Going threw this now witch wedge 😱

Thank you
