Aren't stock LBZ rods supposedly good to like 700hp?

I mean, forged internals are better than the non forged externals Herman has, but...

I have an lb7 (but yeah, supposedly lbz rods are a bit stronger). I'd bet money that what happened had nothing to do with power. Whether it was coolant, fuel or oil I'd bet anything it hydrolocked the cylinder.

that just blows. I figured for that kind of damage it would probably be either hydrolocked on fuel, stuck ring, melted piston, seized piston from too much heat, etc.
 
Re: THe NAC Lots-O-Post Thread

yup. Definitely blows

It looks like I may be on the hunt for a 30 again. I went down to the basement to start working on the one Billy gave me and, well, it was worth what I paid for it...

Took the carrier out. Found a handful of chunks of exploded axleshaft in the area between one carrier bearing and the seal. A chunk the size of a pea was jammed in between the carrier bearing race and the housing, under a carrier bearing cap. I have no idea how that could have gotten in there but it can't be good.

Carrier bearing caps were swapped and bolted on upside down. I suspect that was from when the locker came out of it, so no damage, just funny. Protip: almost all dana 30 bearing caps are stamped with identifying marks from the factory, in this case, they were Hs. One is right side up, the other is sideways. To get the bearing caps on facing the right way around just clean the RTV off the gasket surface and match the orientation mark on the housing with the orientation mark on each bearing cap. This can also tell you if someone has previously swapped on the bearing caps from another housing.

So far, nothing too bad, or unfixable... then I looked at the carrier and said to myself "why is that carrier bearing so far out from the carrier?"

One carrier bearing is pressed on hand-loose, it slides around by itself and the shims came out from under it in pieces. :roflmao: looks like it's collateral damage from an exploded axleshaft beating the shit out of the carrier bearing journal. I pulled the bearing off and I can feel the ridge where the carrier bearing spun on the carrier instead of the rollers rolling.

If I can find my spare stock carrier I might just throw some cheap carrier bearings on it, reset the backlash/preload, and run it.

Not complaining, he gave me the damn thing for free, it's just funny as hell and I wish I'd noticed sooner. Sheep did a good job and beat this axle just enough to use every bit of life it had, but not enough to get stranded.

edit: found spare carrier, looks like I'm half-setting-up some gears.

The MJ. $Free new dana 30, Keith's old carrier, new carrier bearings and shims, new UCA bushings, alloy shafts and alloyUSA ujoints I got from Billy, the good condition (barely even rusted) wheel bearings off the old axle, ruffstuff cover, my aussie, 3.55s, ZJ steering. That's about all the polish I can stand to put on a d30 since I still plan on eventually building the mid 80s kingpin 60 I picked up last summer and throwing it under there.

Looks like 50 bucks in bearings, shims, and ring gear bolts + shipping to set the "new" carrier up properly... I think I can swing that since the entire diff was free.
 
Re: THe NAC Lots-O-Post Thread

Ahh, I figured the MJ.

You can't get the bearings locally?
 
Re: THe NAC Lots-O-Post Thread

I can, but they want 2x as much as rockauto for basically everything even including shipping, and I'd still be without shims. And I'm still not done bracing the housing anyways so I can afford to wait for stuff to ship.

edit:


Came with one setup bearing and one preinstalled bearing! :gee:
