I bought a 926 PRO in 2005 and love it. especially the remote diff. seems to be worth the money. Unfortunately it has not worked as reliably as I would have thought.
When I pull the trigger the 2nd weel does not always kick in till I swing the machien back and forth. then it does not dis engaege until I do the same.
At first i thought it was just a setting or tention in the cord. I adjusted and saw limited benefit. I cleaned the differential cams to allow them to slide more and it seemed to help.
MY ISSUE IS WITH THE DIFF ASSEMBLY THAT IS PART OF THE GEAR I THINK.
I won another 926pro in a raffle and when i engaged the diff I could not get it to dis-engage. I dis-assembled the diff gear assembly and may have found the issue.
It looks like the assembly has t gears on the ID that have springs in the middle pushing the 2 haves away. when you pull the trigger the cam moves the saft which compresses the diff assembly and the 2 halves of the diff engage. when you release the lever the spring in the diff assy should push it back.
Im looking for help with failure modes. does the spring fail often. Is what i am seeing really the issue? I have no snow blower exp. but im mechanically intuitive and it seems to make sense. Im just looking to see if there could be another issue before I put it all back together...yes it is apart and i cleaned and de-rusted all the parts best i cud.
ANY HELP APPRECIATED
THANKS
