rossk Posted May 20, 2016 Author Share Posted May 20, 2016 Seeing as it is 39.71 something tho is it past saving or is there a size it can be reground to and a size bearings to fit? Obviously if it can be saved its getting sent to the machine shop Quote Link to post Share on other sites

rossk Posted May 20, 2016 Author Share Posted May 20, 2016 Cheers, well im past the .25 stage lol so looks like itll be .5 undersized if everything is still true Quote Link to post Share on other sites
5e colin Posted May 20, 2016 Share Posted May 20, 2016 giving you an example in the size 0.00# in the # is 2 overlaping size bearings if you get my drift Quote Link to post Share on other sites
rossk Posted May 20, 2016 Author Share Posted May 20, 2016 Not quite sure mate think im total headfked with this crank tbh heads knumb! Tryna get this sorted then get it away to get forged! If i send to machine shop and get it checked over make sure its not damaged can i just get it reground to 39.495 - 39.505? Then get the .5 us bearings? Quote Link to post Share on other sites
