Kubota BX25 front driveshaft fail.

Please LIKE this video so YouTube will recommend it more often for other Kubota owners to see. thx

I believe the hole is Metric, and a 8mm bolt with a Nylock nut seems to work best as a replacement. I have used both standard bolt or stainless.

I was turning the compost pile with the front end loader, when I heard a click-click-click sound coming from the front axle? The drive shaft fell out, and the universal joint hub was banging on the frame.
It makes me wonder if there ever was a lock-pin since new, as there is no torque on the pin, so it can't break, and no reason the cotter pin should fall out... ??? A standard English size pin passed through the hub, but was too large to pass through the splined shaft, I guess it was Metric? So I ground down the English pin to fit, because I was not going to waste two hours to travel to the Kubota dealer for a 50 cent pin.

Good thing you found it! I wonder it my skid plate would keep it from at least getting lost.

You should spray that thing with oil more often, & put some real TLC time in with grease. Sure the manual doesn't say to grease that shafts but if the other shafts require greasing every 50hrs then you shouldn't have so much dry rust on that one. 1:26 2100hrs though, geez you've got your moneys worth either way.

If you hold one of your front wheels so it can't turn and turn the other wheel the spline where the driveshaft hooks will turn at a steady speed with the wheel. That is because the front diff is an open diff and not posi traction. If the front diff were posi traction you would not be able to turn around corners. It would just want to go straight.

If the pin was never in there it the shaft would of fell off within minutes. The cover part# K2511-1685 is $15.73 an the pin joint part# K2561-16782 is $1.02 at Messick’s

my yanmar 186D has a boot and sleeve so no dust can get in but only has double roll pin for pinion drive shaft connection with no splines .

What size is that pin? Same thing just happened to me and I can’t find a pin size anywhere.

[MDR-hnyz]

I just had the same problem and my drive shaft doesn’t want to go back together.

Poor design dealing with same issue. The driveshaft is too steep going into front axle. Oscilates n wears gears prematurely. Expensive fix.

I break that roll pin at least once a year.

that poor machine needs a going over, thats the worse shaft condition I ever saw. Self inflicted no pity on that one..

Rotate the boot half an inch and drill a new hole.
