ROCKER ARM SHAFTS





Fig. 111

The rocker arm shaft is hollow and is used as a lubrication oil duct. The rocker arm shaft on the inlet side has a 3 mm (0.188 inch) diameter oil passage hole from the cylinder head. The exhaust side does not have this oil passage (Fig. 111).
1. Inspect the rocker arm mounting portion of the shafts for wear or damage. Replace if heavily damaged or worn.
2. Check oil holes for clogging with small wire, clean as required (Fig. 111).
