 Topic: B rear axle nut torque
Posted: 28 Oct 2021 at 3:22pm |
Working on a B that i could not get the rear nut on the thread. Took a nut off another tractor to test to see if the nut or the shaft was the problem.. ( ended up when i slid the hub on the shaft it hit a couple threads)...
The nut i took off the running tractor was only torqued to about 100 ft pounds ( should be 5-600 #) ... Must have loosened up over the last 5-6 years... have 3 other running Bs and decided to "retorque" them all. Out of 4 tractors i found 3 nuts that were around 100 ft pounds torqued... All had 600# about 10 years ago.. No hub movement on the shafts.
Just a recommendation.. Dont wait for one to get loose and start to wobble on the shaft.. Retorque every couple years as routine maintenance !

Very good advice. Same goes for any time a front wheel (or rear wheel hub for that matter) has been removed and remounted. I know my Dad seemed to go thru front wheels every now and then on our WD loader tractor and I'm pretty sure he never went back and retorqued the new wheels after they'd been on the tractor for a while.

I got tired of of the nut working loose, as I recall, on the left rear wheel. Made a strap bracket that formed over two flats on the nut with each end of the strap bolted to the wheel. Stopped it cold.
As a result, I never used the replacement shaft and seal I’d purchased.

So, it may not be an issue of the tapered splines on the shaft and the wheel center wearing a little ?? It's an issue of the nut loosening ?? Good ole red Loctite would fix that when torqued up to specs.

I always thought it was the movement of the splines that caused the wear... Cant say for sure... Its the chicken or the egg story.. What happened first ?

If one put a center punch mark somewhere on the nut and aligned it to another center punch mark on the casting that would tell you if the nut is loosening or not.

You can put a stripe of red paint on the face of the nut and onto threads to check for movement.

We have mid 2000 Kubota farm tractor and their are quite a few white line paint markings across the bolts/nuts/housing on it. Must be a factory check it was torqued.
