Wheel noise..errrnt, errrnt....

[B7500]

That is as close to sound affect I dare to travel. Anyway, my B7500 was making that noise from the right wheel. I thought it was a bearing or something. A call to the dealer let me make a quick fix. I removed the wheel and tightened down the nut that holds the wheel to its axel.
The sound is gone. Hope this helps anyone else who may have the same problem.

My wife makes the same noise.How do i fix that? /forums/images/graemlins/confused.gif

I had the same thing happen at about 50 hours. It's happening again at 190. I did climb under and retorque it, but it's still there. The only way to really torque the hub correctly I have found it to remove the wheel and then the hub, clean it thoroughly and then retorque it.

I get that sound when I drive my B6100 and I forget to release the parking brake. (Which happens all too frequently /forums/images/graemlins/crazy.gif )

The wheels loosening is a known issue. Check them frequently as this can damage the axle.

Thanks,
I just came inside from distinctly hearing that noise on my B7500 - both rear wheels sound like the wheel hub might be slipping under the bolts. . .errrn, errrnt sounds like it.
Now to find the appropriate wrenches. . .

Torque needs to be checked--no stop forget check--verified by thightening the bolts on the axles to the wheel block. If the wheels get loose and work they will slowly damage the shim. They should not be allowed to get loose. Periodic retightening of the bolt may be needed. J

Photos attached. I pulled the wheel and examined the bolt flange - shiney metal can be seen where there is slippage. Look carefully and shiney spots are there
Also, the big flange bolt was loose on the right side.
The flange bolt can be accessed without pulling the wheel.
Kubota's manual requires torque checking the wheel bolts a specific intervals. My tools are inadequate to really tighten up the wheel bolts. Guess I'll make a pit stop at Harbor Freight for some half-inch drives. (By the way, that flange bolt is a 7/8th's inch socket - same as the wheel bolts.)

Man, does that look familiar. Thanks for giving some folks a picture of what I tried to describe by sound effects.
It sure is nice to fix a problem without costing a cent.

Thank you all very much.
I have just finished tighting the bolts that lock the flange to the axle. I have been hearing this noise since the tractor reached 60 hrs. It now has 165 hrs. I asked my dealer about it and was told it was nothing to worry about. Both bolts were so loose you could wiggle the flanges.
Again Thank You for the information.

I recently tightened my right rear after it began making the "ernt, ernt" noise again (great description). The noise persisted. Tonight I was going to have another crack at it, and noticed that although the nut was really tight, the wedges weren't tight on the axle. They appear to have plenty of clearance between them (so as not to be tightened together before gripping the axle). I apparently overtightened it to the point the threads were galled on the bolt, and I had to cut the nut to get it off. Fortunately, the dealer answered the phone, and had a new nut/bolt in stock. A mechanic was working late prepping a tractor, so the counterman gave me a "c'mon down". I checked the left rear hub, and all is well.

I thought of something I should have done AFTER getting it back together. The wedges fit rather snugly in the large hole of the axle. Next time it begins making that noise, it may be beneficial to clean the wedges and the hole they fit in, then grease them up so they don't bind against the hole in the hub as they are tightened.

Any thoughts?.........................chim

That's what I did this last time. I think I am going to put this on my every 100 hour maintenance list.

Chim,

That is exactly what the dealer told me to do. Apparently what happens is the paint wears and then the noise starts. It is a good idea to clean (or remove paint) first before tightening.
