I just took a look under the tractor, and I gave you bad information in my last post, sorry about that!
I have been turning the axle by gear # 22, not #19. The parts you describe stay in the cover (# 59 ) when you remove that cover. I may have simply been testing the axle beyond the problem, if you are correct.

I just looked at the cover # 59 which holds haft #18, which slides onto the gear # 19. I pulled the two parts from the cover, and found the splines to be like new, so that is not the problem sorry to say, as that would have been an easy fix.
Thanks - Carl

The front end of my tractor is up off the ground, and I can either turn the wheels by hand or by the 'input gear". I seems to me that turning the wheel by hand requires a normal amount of pressure. I recall when I first found the problem I jacked both ends of the tractor off the ground, and had it running while in 4WD. The drive wheels were both turning, and then I grabbed the right hand wheel and it stopped, and the left hand wheel started turning, as it should (counter rotate). I then lowered the front end with the back end still up on the 4-wheel jack, and the front wheels would not drag the tractor, no power.
What happened when you sheared the bolts #15 in the Ring Gear?. Was there room for them to simply drop to the bottom of the case, without any other damage, and make no noise once there ?
Is there enough pressure against the ring gear #12 that it could still turn the wheels, although not pull the weight of the tractor?
Thanks,
Carl

Based on your latest info, it is also possible that there is nothing wrong with the front axle at all. There is a chance that the problem lies in the transaxle and the MFWD output shaft. If that turns out to be the case, let me know... I have a spare transaxle as well. :laughing::laughing:
Yes, I checked the lever when I first lifted the tractor off the ground. With it running and in 4WD, the front wheels were turning. Later I then slid under the tractor and moved the front drive shaft shield to see what kind of power I had in the front drive shaft, couldn't stop it with my hands, so I was reasonably sure I had sufficient power to the front axle.
Thanks for asking.

Thanks for asking.

Carl, yes there is enough drag to make the wheels turn with no load. I can't remember right now whether the bolt head fell to the bottom or if they stayed in the carrier. There might not have been enough room for them to fall out of position once they sheared off.
