Technical data

(10) The piston rings differ in shape from one another. Be careful to install them in proper positions
and directions as illustrated and with the stamped manufacturer mark and size mark facing up. In
case of the oil ring with coil expander, the gap clearance of the ring should be positioned 180
degrees away from that of the expander.
(11) Insert the piston and connecting rod assembly from
above into the cylinder block using a ring band. In
this case, make certain the piston ring gaps are
properly positioned and the piston arrow mark is
directed to the front of the engine. After insertion,
properly install the connecting rod bearing and
tighten rod cap bolts to the specified torque.
(12) Install the front plate. Remember to install the gasket and dowel pin. For the W33 engine in
which its crankshaft front ball bearing has already been press-fitted, raise the crankshaft main
bearing cap, and insert the front plate. Then, proceed to the next step.
(13) Turn the crankshaft until No. 1 piston is in top dead center.
(14) Drive the key into the crankshaft and then install the crankshaft gear onto the shaft (except the
W33 engine with its crankshaft gear previously installed).
