B7100HST - Replacing front drv shft+U-Joints

[pacaron]

U-joints next to block was toast, it fell out! But putting them back is a good puzzle.
I'm really not in a mood to install U-Joints up inside the belly of the tractor.
I'd rather do it the easy way (??) anybody know the correct way to install the front drive shaft with the front U-joint?
Remove the joint case at the rear of the front differential?
Can't find the procedure in the books I have.

Thanks,
Ron

Followup...:thumbsup:
On the B7100 HST you do need to take the U-joint case off the front differential that the drive shaft goes into. Take out the front shear pin and remove the U-joint assembly... set it aside. Then put together the entire drive shaft, U-joint and all. (Put in the front shear pin in just enough to hold it until you get the whole thing together.) Install the drive shaft with the rear U-joint pin'd and attached.

Then slide the drive shaft + u-joint to the rear and put the front U-joint on the drive shaft and then slide it on the front differential shaft.
Insert the shear pin and the (3 bolts on the) case along with the shaft cover clamp.
Then install the rear shear pin at the transmission end.

Also it's best if you take the front wheel drive out of gear so you can turn the shaft to line it up with the front differential shaft shear pin hole.

Actually it was good that I did take it all apart, as the shear pin in the front was cracked and fell out after I gave it a slight tap. So that was replaced as well.
Have fun..
