Broken rear axle nut

[Blue Oval]

HELP!! I was just finishing up adjusting the track tension on my machine, and when I was torquing the left side axle nut I heard a snap! I set the torque wrench at the stated 54 ft lbs. but I think I stripped the nut because when I hold the nut and turn the axle bolt I can see the threaded end turning. I can't tighten or loosen the nut. I know that the axle is one complete piece so if the nut isn't the issue and it's the threaded end a dealer close by has a used axle and nut. But how in heck do I get the stripped nut off now ? Has this happened to anyone? I'm of course leaving Sat morning for Maine!

Actually, there is a pin-lock that goes thru the shaft and bolt. Probably broke that pin. I'm affraid you will have to remove the shaft to check it out.

Good luck

Please explain more where this is, a buddy of mine said to try a nut buster. If that works I'm hoping a new nut should thread right on?

If you've got an Apex, there is no cross-pin on the axle assembly. If the nut's stripped, it should come off. I don't have any other suggestions but didn't want you to chase your tail concerning the non-existent cross-pin.

The nut stripping would not make a loud snap, something else must have let go. Also, I don't see how 54ft-lbs should strip the threads. Are you sure the axle is not moving when you turn the nut?

54 ft. lbs. is a lot of torque. While you shouldn't of had a problem with that particular nut since it calls for that specification, it's best if you step up the torque on your wrench until you finally achieve 54 ft.lbs. I just did the track a few days ago (2x) and I set 20, then 30, then 35, 40, 45, 50, and finally 54 ft. lbs. so I know exactly where I stand with the tightness.

I'd say you might double check your technique with the wrench 'cause I've done exactly what you did on my idler wheel torques.

I got the nut off and found out the threaded end of the shaft was stripped! I think I know what I did now , I torqued both sides of the shaft not just the nut side. It ends ok because a local dealer had a used shaft and i bought another nut as well. I slid in a slightly smaller diameter conduit in place of the old shaft and I'll just reverse the process in putting it back in! Thanks for any and all help, Doug
