the mst is not the same as the 920 serise axles. the gears that the mower gang changed are a 15/35 tooth set, and the mst has 11/39 gearset. and the splines are different, so you can't swap in a set from the gears in the shifting cluster. the cases are similer, but not idenical, and the gear that holds the spiders is thicker in the 920 than in the mst.

Yeah the MST also had gear driven reverse. They are totally different trannys, that is why they are different. If they would be the same they would both be MST's or 920's. Rolling Eyes

*cough*FIVE speed mst and *cough* FIVE speed 920 *cough* think about it

ok you guys didn't get it at all. there is no spacer at the end of the cluster, and all trannys have room for 6 speeds. so they are now both 6 speeds! they have a 13:1 high gear ratio instead of 15:1, which means more speed! mst vs. 920/930 Lol

haha i was hoping for better pics so you could clearly see what was wrong, but whatever. here are the spacers:

so if you want more speeds just get some gears from a different peerless tranny and find the biggest one with splines and the smallest one with slots for shift keys and put them on the end in place of the spacers.
