[QUOTE="Dave_Nevada, post: 1498989, member: 29749"] Yeah, I though about the cutoff wheel approach. But I also know O'Tooles law would have bit me hard in the 6, and I would have slipped and buggered the mainshaft. Plunk down another 350 bones for a new mainshaft. Arg! :drool: So MONEY (or me not wanting to spend it) is the main reason I thought of the tube. Choice time: $50 for sure, or possibly $350. I saw $50 as an 'insurance fee'. Hell, I buy insurance to replace what I cannot afford to buy outright, don't you? If you score a mainshaft, you're screwed if you want to run that dude under a load. Those mainshafts are case hardened in the factory, which means, if you gouge them, that's the place it will break under load. Case hardening will harden the surface for wear purposes but leave the core somewhat flexible to prevent stress cracks from torsional load forces. Thus, the only difference between the 7.3 ZF6-650 regular mainshaft and the 6.0 ZF6-750 mainshaft is the case hardening depth. The 6.0 mainshaft is tougher than the 7.3 mainshaft (by design). Ceramic tile can break at the score on its surface, just like glass and any other hard surface. Same idea with a case hardened metal. That said, I'm also one that had the time to figure out lots of 'workarounds' when rebuilding the trans. I brought my 2000 'X' out of mothballs to act as my ride for the interim. but I also recognize not everyone can do that. [/QUOTE]
