14 bolt Bible verification

[CrashKnott]

Re-building my 14 bolt, one of the axle flange bolt-holes (on the hub) is stripped out...So I'm looking for the best/easiest repair.

I'm thinking I'll end up either with a Heli-Coil, or drilling and tapping for a 9/16's bolt to replace the 1/2".

My question is, what are your axle-shaft flange bolts? 1/2-13 or 1/2-20? Mine are 20, but the Bible says 13...has someone already botched this 14 bolt up, and that's why one of the holes has no threads?

 

[Yay!Gurrr]

mine are 1/2-13 both jeep/truck/ and the other 3 i've take apart..

Might try to step up to the closest size metric..

If you drill and tap for 9/16", you will also have to drill out the hole in the axle. I would think helicoil.

When I bought my 14 bolt, one side had been drilled out for 9/16" bolts. The bolts were too short(minimal thread engagement) and had stripped out the threads in the hub. I bought another 14 bolt for the hub and axle so I could fix it correctly.

So the consenus is heli-coils for my fix?...stupid PO costing me more and more money.

1/2 - 13's then?

Also, you guys are torque'ing down 115 ft. lbs on these, right?

 

[Cperry]

i wonder if a helicoil can hold up to that torque. I knew these torqued to alot, but 115 is alot for such a small bolt.

Yes, after the trouble with mine, I referred to the 14 bible for the torque spec and set mine to that.

 

[CrashKnott]

The helicoils should end up being a stronger female thread than the stock threaded hub. They spread the torque out over the entire threaded hole instead of just the first 2 or 3 threads like a normal bolt does.

I'm waiting for my ridiculous $85 kit, then I'll report back
