Saw your post the other day asking for the specs on a 3306 crank. Sorry for the delayed response but I"m moving stuff from Dad"s shop to mine and things are in a bit of a mess so it took me a while to dig out one of my books. That said, here are the specs for you.
MAIN JOURNALS
3.4992 +/- .0008
For the undergrinds simply subtract .010, .020., or .030 from that. They all have the same +/- of .0008
ROD JOURNALS
2.9992 +/- .0008
Same as above subtract the standard for the undergrind and keep the same +/- tolerance
If you need it, the clearance on the actual bearings are as follows.
MAINS
New .0030 to .0066 with a max of .010
RODS
New .0030 to .0065 with a max of .010
Again sorry for the delay. Hope these help. I"ve got the book close now if you need anything else.
