The replacement process starts with removing the valve
Rocker Arm cover while holding valve rocker arms and pushrods and pivot support in a rack according to their original positions for preservation. After removing the valve Rocker Arm bolts, the valve rocker arms and valve Rocker Arm pivot support and pushrods can be taken out. A systematic examination of valve rocker arms and pushrods should be conducted during cleaning and replacement preparation before the reinstallation of reused parts into their previous positions. Valve lash exists only as a natural build inside the system making any adjustment unnecessary. Clean engine oil should be used to lubricate both valve rocker arms and pushrods while also applying oil to the bolt flange of the valve Rocker Arm. Structure the valve Rocker Arm pivot support next, placing the pushrods correctly into valve lifter sockets and Rocker Arm ends before you avoid tightening the Rocker Arm bolts. The number one piston should be facing tdc compression while the
Crankshaft sprocket key rests at the 1:30 position. The engine should be positioned at its number one firing position for torqueing the exhaust valve Rocker Arm bolts of cylinders 1, 2, 7, and 8 to 30 nm (22 ft. Lbs.) and the intake valve Rocker Arm bolts of cylinders 1, 3, 4, and 5 to 30 nm (22 ft. Lbs.). The Crankshaft should first be turned 360 degrees before tightening the exhaust valve Rocker Arm bolts on cylinders 3, 4, 5, 6 to 30 nm (22 ft. Lbs) and the intake valve rockers for cylinders 2, 6, 7, 8 to 30 nm (22 ft. Lbs.). You should install the valve Rocker Arm cover as the final step.
