Torquing the Crank Bolt July 22, 2019July 23, 2019 ~ Joe Ernst The custom tool holds against the frame rail so I can use a 27mm socket on my 3/4″-drive breaker bar to tighten the crank bolt. It gets torqued to 200 nm (148 ft-lb), and then tightened another 90 degrees. Published by Joe Ernst View all posts by Joe Ernst
