Use Tool (A) to install the camshaft bearings in the 3304B and 3306B cylinder block.Note: The camshaft bearings in the 3304B have pressure lubrication. The intermediate camshaft bearings and the rear camshaft bearings in the 3306B have splash lubrication.
Install the camshaft bearings in the 3304B cylinder block, as follows: (a) Install the front bearing to a depth of 0.57 0.5 mm (0.022 0.02 inch). Ensure that the oil holes are in a horizontal position and that the camshaft bearing joint is at the top of the engine. The camshaft bearing joint can not be more than 15° degrees from vertical in either direction. (b) Install the center bearing to a depth of 303.2 0.5 mm (11.94 0.02 inch). Ensure that the oil holes in the camshaft bearing are in alignment with the oil holes in the cylinder block. (c) Install the rear bearing to a depth of 604.9 0.5 mm (23.81 0.02 inch). Ensure that the oil holes in the camshaft bearing are in alignment with the oil holes in the cylinder block.
