GENERAL All torques specified in this manual are assembly torques and typically can be expected to fall off after assembly is accomplished. DO NOT RE-TORQUE after initial assembly torques fall.To convert inch pounds of torque to foot pounds of torque, divide inch pounds by 12. To convert foot pounds of torque to inch pounds of torque, multiply foot pounds by 12.foot pounds x 12 = inch poundsInstalling Crankshaft
If the crankshaft is fitted with oil seal rings, install rings. Position ball bearing(s) and crankshaft in crankcase, making certain the drive end of the crankshaft is positioned in the crankcase as marked before disassembly.If one end of the crankcase is counterbored for a ball bearing, make certain the crankshaft is installed through the correct end of the crankcase. Carefully press the crankshaft and bearings into the crankcase.Position a new rear end cover gasket over the rear end of the crankcase, making certain the oil hole in the gasket lines up with the oil hole in the crankcase. Install end cover with oil seal ring (if used) on crankcase. The end cover should be positioned correctly in relation to the oil holes in the gasket and crankcase. Install cap screws with lock washers and torque to 175-225 inch pounds.If the opposite end cover requires an oil seal, the new seal should be pressed into the end cover. Install a new end cover gasket and carefully install end cover over crankshaft and to crankcase to avoid damage to seal. Install cap screws and lock washers and torque to 175-225 inch pounds.Pistons And Connecting Rods
