B6100HST 4x4

[bpicard]

I just bought the little tractor and it runs nicely. There is one problem, however, with the front axle pivot assembly. It appears to me that the differential/axle assembly should only rock side to side, however, when the steering wheel is turned, the differential/axle assembly appears to move backward on the pivot pin nearly 3/8" or possibly more. It seems like a bushing or two is missing, perhaps worn out to the point where nothing is left.

Does anyone have an exploded parts view of the assembly?

Are any of you familiar with the problem?

As the whole axle and 4x4 diff' moves backward, is it possible that the front wheel drive line is damaged from the movement?

Thanks in advance.

Brian.

The movement is closer to 1/4". I could really use some help on this. An exploded parts diagram would be great.

Thanks.

I have the gear drive model and I don't recall any movement like you mention. If I understand you correctly, these pictures may help you out. As for harming any of the driveline, I doubt it because there are u-joints and a splined shaft inside that boot attached to the front differential.

Mike,

Thanks for the quick reply and parts diagram. I was told by my local Kubota guy that there are some shims that have likely worn. I'll need to drop the differential to replace--I don't know what's involved with that but here goes.

Thanks again.

Brian.
