Have a block that will need to be cold tanked, and line bored. Going to also post the question on the Samba, but figured I'd ask my 'peeps first. I know I can ship it, but prefer not to.
Well, in due time. But why cold-tank the case if it is junk? Just clean the parting surfaces, torque to 25 big/13 small and send it in. If it passes the test, then it can be tanked. If it needs an align-bore, well, it will need a cleaning after.TrollFromDownBelow wrote: ↑Mon Feb 25, 2019 7:42 pmokay. I can do that. Although won't I need a machine shop to do the cold tank, and polish or grind the crank?
I truly love these bits of wisdom....and no, you are not repeating yourself - I took rather copious notes when you were here last summer - just read them tonight - this wasn't in there. :)Amskeptic wrote: ↑Mon Feb 25, 2019 8:37 pmWell, in due time.

The crank is an independent operation whose passage through the machine shop checking process will yield your crank side bearing numbers, ie STD, .025 .050. If the crank needs only a polishing, I prefer to do it myself. Then get it professionally cleaned.
