[QUOTE="whenfoxforks-ruled, post: 1351748, member: 73147"] I took 1,000 hours of machine shop training in school. I followed up with working in various job shops for around 10 years. I really do not assume anything, but the worst is fact. You take the crank, blue it across the flywheels, scribe a line. Take it apart and use the line to realign. Brand new oem cranks have been rumored by Jr. Jackson no less, to be as bad as .010 on the run out. You set the crank between centers, and pop the flywheel, with a hammer(better than head butting it) till its within spec. This is the way it is still mostly done! Eric uses a special jig, not many others do. Eric probably uses a hammer to get any with issuesh within spec, it is the only way! If a guy, holds the right side with a wrench or what ever, and impact or whatever to get the other nut off, it can twist the flywheels out of spec. IMO, a backfire can knock it out of spec! I have access to presses, it is truly no big deal, 15 minutes with a coffee break! Shop rates in our area, the appliance repair guys are getting 75 dollars an hour! Piece of mind and letting a pro do it, priceless. Eric is modding the rest, so stick with the best! Chances are best that he can get a package deal, he does know a guy at wiseco/hotrods? [/QUOTE]
