ROCKER SHAFT WASHER:
To improve serviceability, a new two-piece rocker shaft washer has been made available as a supply part (see Fig. 1). This new two-piece rocker shaft washer can be installed without removing the rocker shaft bolts/cylinder head, and is designed for field fix only. The two-piece washer is not used in production.
Note: On vehicles equipped with the resin type washers, it is not necessary to replace rocker arms that show signs of wear. The new two-piece washers are larger in diameter and will contact the rocker arm outer surface not worn by the original resin type washer.
