BX23 4x4 Drive Repair

[ValRioFarms]

Hi all,
I own a little BX23 which I loan to one and all. I am a single woman and I've found that the more helpful a person is, the more help you get in return.

I loaned my BX23 to a neighbor and never noticed that the 4x4 train was damaged until I went to use the tractor yesterday. I'm not mad, I just need some good advice from the knowledgeable folks on this forum.

I have read this forum for years and I know that I need to purchase a repair manual if I'm going to try to fix this myself. I believe the best place is SSB Tractor ($79.95 for the Service Manual).

Does anyone have any knowledge about this kind of repair that they can pass along? I am not afraid to try this myself, but I know there are people with lots of experience that might keep me from making a mess of this.

Thanks in advance for any help you can pass along. I've attached pictures to this post so you can see what I'm talking about. The damaged part is the part that is hanging down - unattached to anything - on the right in each photo.

UPDATE:
Per everyone's help I've attached a better photo. With your help I was also able to better identify the missing parts.

Go to this site and download the parts manuals for your tractor I see 2 different ones and I would download both this will help to see what all is missing. Second take some higher resolution pics so we can have a better look at it. From what I can see you are missing the back section of your front wheel drive but I can make out much detail in the provided images.

It looks like you are missing the rear universal joint. I am not sure if you are missing anything else. I would email neail at messicks.com and ask for the exploded view of the front wheel shaft of your BX23. Is the unit still in 4 wheel drive ?

i would say rollpin came out and or sheared. look where you have been working
you should find the rest of your pieces. i replaced pin with bolt and nut no trouble since. i was working on a extreme hill with 4wd when it broke.

You really need to get straight what happened such that you can figure out what your neighbor might now owe you. If my neighbor did that to a borrowed machine of mine and did not tell me about it, trying to sneak it back to me, they would be missing some parts of their own for life. That's NOT acceptable, single woman or not.

Figure out when it happened, either you did it or they did it, then write them a notarized letter if it was them.

You are missing the rear most universal joint it is pinned to the shaft closest to the transmission and slides in and out as the front axle changes position.

It looks like item #160 part #K2561-16820 for the universal and o5411-00650 for the pin that holds it on.

I am always take aback by the willingness of some people to share what they know with strangers. Each of you has given me a piece of information that I will be able to use.

Thank you for taking YOUR time to read my post. I will do as each of you has instructed including posting better pictures; getting an exploded view of the assembly, etc.

More to come. Many heartfelt thanks!

$63.72 just for the U-joint.

I just purchased a used BX2230 and it was missing the exact items. I purchased the ujoint and shear pin and it was easy enough to fix. The problem I now have is when the tractor "flexs" too much it allows the drive front drive shaft to slip out of the u-joint.

Looks like you are missing parts #160 and #180 according to the attached PDF. I would go ash the previous borrower if he has found anything like this. It would be cheaper than buying one. You would probably still have to buy the pin though. I didn't see post #6 he has you covered.

I just replaced mine last weekend. I was lucky and I found my u-joint/yoke were I was working, but I was unlucky in that I was turning over a pile of manure when I lost it..

The hardest part of it was finding a store that carried the 6mm roll pin that holds the yoke on the shaft. You'd think it would be easy, but ended up having to go out to a dealer to get it. Take it out of 4wd, put the yoke on the front shaft first (it only goes on in one position so you may have to turn it until it aligns). Then hold the front shaft with yoke up to the rear shaft and turn the shaft (shaft will not turn unless out of 4wd) until the yoke slips onto the shaft. Set the pin straight with a few taps, then drive it home.

From the looks of things, you may need to take a wire brush to the shaft ends to clean them up then grease them good.

How long has the part been missing? Pretty rusty for a recent event.

when the tractor "flexs" too much it allows the drive front drive shaft to slip out of the u-joint

You may be missing the cir-clips that hold the shaft out to the correct length. Or the front yoke, by the front axle, has lost its pin..

Something to check is the clocking or position on the shaft in relation to the other ujoint, it could cause that or vibration. In the service manual it shows both ujoints on the angeled shaft on the same axis or orientation.

The new picture look so much more clear. Definiately the u joint is missing, and I second conur the comment about rust on the shaft on one end. Hopefully you can order a new joint and install.

Id measure the shaft sizes and get the joint at an auto part store .Alot cheaper and id get one with grease fittings.NAPA sells them

Tom is exactly right with his prognosis and parts numbers. I have a BX23 that had the same thing happen. The roll pin will shear off and the U-joint and yoke assembly will fall to the ground. I obtained the parts Tom listed from my local Kubota Dealer and replaced them in only a few minutes. The U-joint and yoke assembly cost $72.36 and the roll pin was $.96 out here in California. Its a very straight foreward repair that you should be able to handle with a little mechanical ability.
Good luck and post back if you need any further info.

FINAL UPDATE - IT IS FIXED
About two weeks ago I came to this forum asking for help.

I did not know the right terminology, much less how to detail my problem. I did the best I could and posted my question and included a photograph of what was broken.

In less than 4 hours I had 5 replies - all of which were helpful.

I ended up with more than I ever imagined. One reader in particular (tommu56) knew that I would never get anything fixed without knowing the parts and installation sequence. He carefully guided me along until I could get the part.

This weekend I installed a new universal joint is on my 4x4 driveshaft and my BX23 is back in business. Thanks to everyone.
