Impressive breaks/failures

Aluminum rod out of my friends 12,000hp top fuel motor...

What model year is the machine?
Any bets pre war :usa: and not china?
That's impressive if not chineezium.

Not chinesium. Most are war effort machines from the early-mid '40s. 4140 spindles

The one with the broken off chuck is an American Pacemaker from WWII
The headstock torn down in the shop is a similar vintage LeBlond

It is pretty wild tearing them down and seeing stuff like this.

I think I posted in the last FNLC about a new noise on the jeep. Tore it down last weekend and found this. I did some snow wheeling a while back and had a wheel loosen up, tightened it back up and moved on with life. I guess I should have taken a closer look. Not sure if the loose rim caused this or this caused the loose rim. Terraflex decided that these dual pattern rotors needed to have their name and specs recessed into the face and that certainly did not help.

YUP, stress concentration for sure... especially when the name stamp is right at a high stress point where the lug comes through. Would have been fine on a smaller bolt pattern, I bet.

Good news is that I had my old 5x4.5" rotors around and used the broken piece as a guide to drill the 5X5.5" pattern on them. They are much beefier in that area.

I did order new lug studs and E-brake shoes and hardware. The noise that made me tear it apart was the E-brake shoe retainer broke and was clacking on the back of the axle.
 
Here's a John deere 330 skid steer with a warped quick tach plate.

got sent out to fix a skid steer grapple

I walked around the corner and there it was, with the loader arms hanging out of the Q/A :laughing:

loader wasn't even around, I have no idea where it was

people with no consequences can really screw things up

I knew better than to ask questions, I just told them to load it up
 
My 8.8 that has been welded for the last 20 years finally let go at the Badlands a few months ago. Was able to drive it back to the trailer from the quarry. Even reused the ring and pinion. We’ll see how long that lasts.
did you weld the side gears to the pinions, or did you do the deal where guys just weld up a couple teeth to keep it disassembleable and hope the wedging forces don't snap the diff case?

I've always figured on welding everything together real good, then weld the ring gear side side gear to the diff case, so the power ain't even gotta go through the cross pin
 
Too much lift and big tars? Looks like the female yoke was way down the splines.

If you meant a old 1 ton flatbed you would be right.

Slip yoke had part of the shaft broke off in it
 
That's one way to reach all the grease zerks.

didn't get any pics of the bits before I started reassembling them, so here's a pic halfway into reassembly
only welded one side of the spiders, they broke and fell out and then trashed the ring and pinion
well, still running the r&p minus one tooth, but I do not trust it at all
stuck the broken bits back into the diff carrier to play the part of filler and packed it with tons of weld because fuck fuck fuck

Having a spider gear get caught in the pinion makes a loud noise and locks both duals up for a good 10' or so
ETA: 10.25" ford

Did you ever fuck around with welding front-wheel-drive differentials In a transaxle?

nah not yet
might in the future though, got some thoughts rattling around for something to do to one of my vehicles...
