can you overtighten the rear axle? I backed the axle out to pull the tensioner wheel. it was really tight to start. i counted 18 revolutions of loosening. when i tightened it, it went a total of 19 revolutions before it was tight. i could have lost count. and yes, i did first loosen the pinch nut,

thanks

Read my thread on the oil drain getting stripped. The swingarm metal is VERY soft. I'm guess that YES, you can overtighten it.

ok then. i tightened it about as far as it would go but didn't jump up and down on the wrench. i just had this vision of the axle spinning out while i rode, throwing me to the pavement. i pictured myself surviving the fall but not surviving getting run over by the next 8 cars on the beltway behind me. did about 50 miles today and all looks well

I thought the rear axle has a torque spec??? 23-27ft/lbs .... back off 2 full turns then 48-52 ft/lbs. USe the anti-sieze.

Sears sells torque wrenches

thanks Dave - that's the kind of info I was looking for. picked up the torque wrench today (at Sears) on my lunch break hoping somebody here would give me the specs. I have to get the shop manual...

thanks again

Yep, that's the spec.

Just like the spec for the oil drain plug is 29-35 ft/lbs. Mine stripped out with the torque wrench set at 30 ft/lbs. YIKES!

Perhaps my torque wrench is in need of adjustment.

The axle threads do seem to be more stout.

Chadhargis,

I have started to put the oil plug at 14 ft. lbs. which is 168in/ lbs. which is the same as the tranny plug. I might go to 144 in./lbs. after reading your post. Thanks for the heads up!

Chad I've had the same thing happen with the clicker style torque wrenches.

I would send yours out to check cal, but FWIW mine was spot on.

I've since mixed torque specs with common sense...AKA, still use some feel.

Yeah Chad I saw your post and feel your pain. Threading into aluminum...it'd be interesting to know if all XBs have the same spec on that bolt. I always reserve the right to tell the factory manual to 'go to hell'.

Makes me worried about the rest of the torque specs. When I reinstalled the bolt after the repair, I didn't use the torque spec. I just tightened it by feel. I'll keep an eye on it. So far, no leaks, weeps, or other badness.
