After torquing the main caps to 95 ft-lb, the crankshaft still spun freely when turned by hand. Prior to installing the pistons, we checked the ring end gaps. Though you can buy tools that will square a ring inside the cylinder at the proper depth for checking, we just used a small Allen wrench, checking several spots around the ring to make sure it was square. If it isn’t, the end gap measurements won’t be accurate. We measured 0.022- and 0.024-inch gaps for the first and second rings, respectively.
