NN2 Posted February 25, 2009 Report Share Posted February 25, 2009 I want to know how a crank is aligned and trued. Not that I am going to do it myself but like to know how things are done. If it's out of alignment, what does a builder do to the crank? Just curious. Quote Link to comment Share on other sites More sharing options...
deckheight Posted February 26, 2009 Report Share Posted February 26, 2009 The crank is placed on a fixture or V-blocks resting on the bearings, indicated and then smacked around with a mallet until it is within spec... Real high tech! :biggrin: :biggrin: I am on dial up so I didn't watch the video in the link, but the description sounded pretty good and mentioned "phase" for a twin cylinder. http://www.greenhulk.net/forums/showthread.php?t=38113 Quote Link to comment Share on other sites More sharing options...

Hammer and chisel, no problem :biggrin: I didn't watch the video because I didn't feel like registering to be a member but the description made plenty of sense to me. Very similar to indicating parts when turning. I never realized that a crank was that easy to change run out on. Quote Link to comment Share on other sites More sharing options...
deckheight Posted February 26, 2009 Report Share Posted February 26, 2009 Didn't know about "joining" Greenhulk... Try this link, looks like the same video. I took the time to load it on dialup. If you have never trued a twin (or triple like the video) it is worth watching. http://www.slednutz.com/showthread.php?t=36 Quote Link to comment Share on other sites More sharing options...
