3-Point Hitch Broke my PTO Differential Gear Case. Bearings shattered!

Always interesting to see inside equipment.

As to the paint, the chassis is painted after assembly so replacment parts like that will typically be bare metal.

If you don't want to buy the kubota paint from the dealer I've found that rust-o-lium "charcoal gray" is a very close match.

Agreed. I bought a quart of rustoleum charcoal gray to paint a bracket for rear remotes on my new B2650. Along with some touch ups. It was pretty close. If your want to get it even closer you can SLOWLY add some gloss black to darken it just a little bit and it will be perfect. Don’t go to much tho because it darkens while it dries. This worked great for me.

Nice progress. Are you still taking to a shop to get the bearings reset?

Interesting enough, the bearings are easily pressed in by hand. They are a tight fit but nothing like some of the motorcycle transmissions I've done were you need a puller and a press. Both axles came out with little effort. They have bearings that sit in the case as well. The bearings can all be gently taped in with a rubber hammer and a piece of wood. So it seems I won't have to be taking this to the transmission shop after all.
I had to order a couple more parts. Mostly I'm waiting on the dow pins. The old pins were too hard to removed from the case. These are critical for keeping the axles stable. Also, there were a couple of dow pins that sheared off on the PTO cover. So as soon as these arrive I will get started on the reassembly.

Thanks for the tip!

Kubota is really proud of their rattle can paint, its like $13 a can. By the way the Kubota bright orange...is actually the current darker orange. I purchased the other one thinking it was darker, its much brighter than the bright orange. (face palm)

I did purchase the Kubota Gray paint. I will say that it did spray quite well. It matched the other gray perfectly.

I finally found time to finish the Kubota and get everything back together. The one thing I didn't like is the fact that Kubota didn't use any kind of gaskets. They rely on silicon sealant only. I made sure all surfaces were perfectly clean before I reassembled the parts. For those who are curious what it looks like internally, below is some photos of the axles and lift arms before I installed them.

Nice job.
Looking good.

Aluminum has a tendency to absorb oil and other chemicals. So after installing everything I decided to paint the new case. I first used a 2 part mix epoxy primer. Then I used the Kubota brand gray paint.

I also have a photo of the slide and lock feature. The slide and lock isn't much of an advantage if you ask me. Although it was completely my fault, this is what contributed to the PTO shaft breaking my case. When I hit a small rut in the field I lifted the tiller and these slid in and locked shorting the distance between the tiller and the tractor. When I let the 600 pound tiller back down it shattered the PTO bearings and differential case. It was one of those moments.... standing out in the middle of the field and seeing hydraulic fluid pouring out the back of my tractor thinking to myself... why didn't I take the time to size the PTO shaft? What can it say?



While I had everything apart, I did some upgrades. I had purchased a quick hitch I didn't find it to be quick at all! Most of the time I struggled to get the equipment hooked up. I use a lot of different implements and they are not all from the same manufacture. I always had to adjust the top bar at the very least. And if the implement wasn't on level ground it was very hard to hook up. So I purchased a pair of Pats quick hitch lift bar links. So far they have worked wonderfully. Much better than the Kubota quick hitch. Below is a photo of them installed on the Kubota B3200. Just a quick note the slide and lock feature no longer will work with these mounted. The are too big and don't allow the link bar to fully retract and lock. I will purchase new lift bars without the slide and lock feature soon.
