DK35 4 Wheel Drive not working

[KiotiDK35]

With 795 hours on my DK35 and no problems until I heard a snap in the tranny case and the 4 wheel drive is no longer working. My question is if the drive shaft to the front axle can be removed without removing the front axle? I am hoping it is just the coupler that joins the drive shaft to the spline shaft in the tranny. There was the loud snap, but there isn't any noise with the 4 wheel drive engaged or dis-engaged, I consider that a good sign.

Say...do you have front chains on your unit? Sorry to hear about your problem. Is it still under warranty?

Not running with front chains, and was working in soft ground moving dirt with loader when it happened. Warranty is long gone.

Marty,
When you find out what happened please let us know what it was..

Jon, I am in Wichita. I will keep your number handy if I need to give you a jingle. I have the service manual, but it doesn't go into much detail on what all needs to be removed to get the drive shaft out. The good thing is that the dealers I have called locally, have never had a problem with the DK35 four wheel drive, so that is good. Thanks again Jon

Vince,
I will let you all know what I find out. Since there isn't any noise coming from the tranny while operating I am going to bushhog some bluestem I have to get down, before tearing into the tractor, hopefully I can get it diagnosed and fixed before mowing season begins.

As a fellow DK35 owner, please keep us posted.

BTW: Depratt...you are a true gentleman...I wish you were my local dealer.

Update on 4 wheel drive not working:

I finally had some time this afternoon to remove the tube cover on the front wheel drive driveshaft. The shaft will turn freely by finger tip with the four wheel drive disengaged, but when engaged it will not turn and I can hear the gears mesh in the transfer case. With the front axle grease leaking around the shaft adjoining the drive shaft, I am assuming that the bevel pinion shaft has broken in the front axle and the seal is torn allowing the grease to come past it. I am going to remove the front axle and take it to my dealer this weekend, for him to repair. I am glad it is in the front axle and the tractor will not have to be split to fix.

Thanks for the update.
Keep us posted on the final outcome.
At times I get to bulldozing dirt and rock piles pretty hard with my DK 35. You never know, It's possible I could break the same thing some day.

Vince,

Out of the 800 hours on the tractor I would say 500 hours have been spent using the loader for digging and dozing. Like you said I push the tractor to it limits and beyond at times, is amazing the amount of digging and pushing dirt the tractor will do. I forget at times it is only 35 HP. I will post the final find of what went wrong in the front axle.

My dealer called today and said the front axle will be ready tomorrow, bad thing is I will be leaving town for a week, so there will not be time to get it put back in for a while. The dealer said it was one of the bevel gears that drives the shaft from the ring gear, the bevel gear collar cracked on the splined shaft and slid back onto the shaft, not meshing with the other bevel gear. There were not any stray pieces of steel floating around in the axle from the break, and the cost for parts was $70.00, I don't know what the labor charge will be, but I think it will end up being a reasonable price. I was figuring a thousand dollars when it first happened, not knowing for sure what the problem was at that time. My dealer had no problem getting the parts and has really expedited getting it back together considering he has only had the axle for a week. I am looking forward to getting the axle back on the tractor for more hours of seat time.

Thanks Marty for keeping us updated.
Hope your labor cost is reasonable.
