Technical data

(1) When the camshaft front bushing needs to be
pressed in, align the bushing oil hole with the oil
hole in the cylinder block as illustrated. To align
the oil holes, draw an oil hole mark (with
marking ink) on the front end of the cylinder
block. After installing the bushing, make certain
the oil holes are properly aligned.
(2) When the idler gear shaft needs to be pressed in, observe
the illustrated direction of installation and length of
protrusion.
(3) Install the main bearings to the cylinder block and main bearing caps.
(4) Install the crankshaft. Apply engine oil
to journals and pins.
(5) Install the main bearing caps, then tighten cap bolts to the specified torque. Each cap carries an
embossed arrow mark and numeral to prevent incorrect installation of the caps. When installing
the No. 1 and last caps, apply sealant to the upper surface (cylinder block mating surface). For
the W33 with its crankshaft front bearing previously fitted, however, first install bearings
temporarily without sealant and, after performing step (12), carry out steps (5) and (7).
