Kubota G1900 shaft replacement..tips on how?

[Sniggle]

Hello,

I have an old G1900 (1200 hours) that needs a new drive shaft (old one was flopping around and making quite a racket.

I bought all the parts needed for a new one (my tip: individual parts are cheaper than buyin the whole kit now, $214 vs $280). I have partially assembled the new drive shaft.

It looks fairly simple, but before I crawl under the tractor to remove the old and install the new, I thought someone here might have done it and could give me some pointers.
The projuect will not be until mid march, as I will need to remove the plow before tackling this.

Thanks in advance.

Well, I finally got around to replacing the drive shaft.

It was difficult but doable...took me about 2.5 hours.

Lots of that time was spent trying to figure out how to remove the old drive shaft and then how to get the new one in place. The drive shaft must be taken out and fed in from the area to the left front (when facing engine) of the engine compartment. It will take some work to get the old one out and the new one in, but the will fit without having to take apart anything else on the tractor.

You also need to remove the shaft plate that connects to the engine (3 bolts), pull it out, and then work it back into position when the new drive shaft is in place.

The shaft parts cost about $215. Note that the shaft replacement kit is $300, so it is better to just have the dealer order all the parts.

My G1900 runs like new again (no flopping drive shaft). And I saved about $300 that the dealer would have charge me for labor.

The shaft just slid off the pump spline on my G1900 and flopped around making quite a racket as described above. I managed to reach up in there and slide it back on but could not get the holes lined up to insert a cotter pin (there is no sign of what was there originally and I see no service manual or parts list on the web for reference). I ultimately gave up and put a hose clamp around the spline at the engine end to prevent the shaft from moving forward enough to come off of the pump end. That got me back to the barn where I jacked up the rear for better access but still couldn't get things lined up, so I hope the clamp proves to be a long term fix.
