CAUTION

Much higher accuracy is required in the rocker arm installation (at the intake side). Therefore, mis-
takes in the rocker arm installation procedure might cause the operation failure. At the overhaul, 
surely tag the set of Rocker arm "A", T-lever and Rocker arm "B" and then remove the set. At the 
assembly, install Rocker arm "A", T-lever and Rocker arm "B" to Rocker shaft in accordance with the 
tag made during removal.
