mac said:What I can't understand is - why doesn't the freakin' expensive FSM say ANYTHING about ovality of the cylinders? Even though it instructs you to measure @ axis & thrust points, it only gives max wear #'s in general. There is no comparison of the two figures.
BC Cruiser said:Ok, just cleaned off the dust and cracked open one of my diesel textbooks from school. They spec in the book .005" (.127 mm). So you should be measuring at the top of the cylinder, about an inch down from the top so your not measuring on the cylinder ridge. And then the same at the bottom of the cylinder. Now this is out of book for large diesels like cat, so your measurement might be smaller.

Why would an out-of-round measure matter in a non-rotating application like pistons and cylinders? Aren't the max/min tolerances the important measures? As long as the clearances are within spec, (no binding, no slop) can't an oval piston work fine in an oval cylinder?
Thanks,

light_duty said:Peter, did you see that guy selling brand new 1HD-T short blocks from Japan? I think he said $4000 shipped, 5-6 days air freight from Japan. It was a thread in the vendor section.
Just a thought.
mac said:Well, so much for rebuilding. Anyone need a 1hdt block, rods & pistons? I'm going for the factory new shortblock. Thanks to Rob from RADD and James from JDM for all of your help so far. Thanks also to you Light_Duty for puttin' me on to the ad. Now the waiting game begins- oh well I have a head to clean up! Oh yeah, and a 62 diesel conversion that I'm still working on... I've been neglecting her...
Cheers for now,
Peter
