Broke my B26TLB rear axle shaft

[ultrarunner]

All of mine will get done if I can figure out how to live to about 130

For some of my friends it’s more declining ability such as eye sight or no longer able to be a contortionist.

It would be real nice to get a reason of the break. But not around anybody that could look at it with the proper knowledge. Jon

Did you keep the broken parts?
Post closeup pics of each side of the break.

Yeah also,
if OP or a friend have a lathe, that axle shaft steel like (SAE 1045, chrome-moly 4140, 4340,15410 ) is handy to have laying around and is Not inexpensive to purchase.

No the broken parts were left at the repairing dealer. Assuming by now, in their scrap bin. Jon

Sunday was not a good day for me. Was supposed to be an easy day, haul some dirt back to a clearing to level a spot for a deer blind. On about the 3rd trip back, and just into the clearing, thump, and right rear corner droped down to the ground. Wheel was on an axle, and no the lug nuts did not just come off. They were all there and tight. Got off the tractor and saw the remaing shaft in the outer bearing sheared off and fluid running out the shaft hole. Was able to release the latch on the backhoe and drop it back to the ground and also get the out rigger down. By this time, very little hydraulic preesure left in the system. Shut the engine down. Went back to the house to get some jack stands and the 4ft tall farm jack on the other tractor and went back out. Also brought cribbing. Was able to lift it up on the backhoe frame and get the stands undet on some 2x's.

Left till this morning, and called local dealer. Described the situation to the service write up person. Told them which part number the axle shaft was. They agreed and added some other items, ie bearing, seals, to the estimate and pick up and delivery and repair labor to fix. I said today was nice, rest of week rain was forecasted. All morning their phone has been off the hook from all problems that were created on a long weekend by the visiting weekend warriors. They couldn't tell me when they could pickup but the driver would call for directions.

Now the wife and I had to open the trail large enough for their rollback with my tractor on it. About 2pm, driver called and said he had a delivery in my area and would come by afterwards to load mine.

He arrived by 3:30pm and by 4:30pm he was pulling out of the clearing. So now I wait. Jon

Sorry to hear about your misfortune... Is your cab easily removable
[looks like maybe} What brand is it ?

 

[civilian]

The cab is by Sims/Cab Depot in Canada. This was old new stock someone had. I installed it on my backhoe. When dealer removed it, I was not there to see how they did it. I was told they removed it. But both doors were off for the summer when the axle broke. So when I put the doors back on this fall, I had to make adjusts to get them to fit correctly and to close properly and latch. Jon

Jon, just saw this thread. Glad it worked out got you.

Did the dealer have any idea what caused the axle to snap like that?

I was amazed when I saw the pic. A super clear picture sure showed the clean break. I found it shocking to tell the truth.

I will guess the cause was the tire ballast was not removed when the backhoe was on. OP indicated tires were loaded in post #8.

I no longer own my TLB but the manual says for the B26tlb the rear ballast (loaded tires) should be removed when the BH is attached. So maybe a rear end overload situation??

Could be. Dealer installed ballast when I bought it used, but have never removed the backhoe. I have no need to remove it. Jon

will you remove the ballast now or the backhoe to match up with manufacturers weight warnings or going to continue to run with both?

cheers

I've had my B26 for about 10 years give or take and it had loaded tires when I got. I have never unloaded them but I have used the three point hitch a lot bush hogging and such.
