INSTALLATION
NOTE:
For installation follow the relationship between the matching mark on
each timing chain and that of the corresponding sprocket, with the
components installed.
1. Install the crankshaft sprocket and the oil pump drive related parts:
a. Install the crankshaft sprocket (1), the oil pump drive chain (2),
and the oil pump sprocket (3) at the same time.
• Install the crankshaft sprocket so that its invalid gear area (A)
is toward the back of the engine.
• Install the oil pump sprocket so that its protrusion faces the
front of engine.
NOTE:
There is no matching mark in the oil pump drive related parts.

• Install by aligning matching marks on each sprocket and tim-
ing chain.
• If these matching marks are not aligned, rotate the camshaft
slightly to correct the position.
CAUTION:
• After the matching marks are aligned, keep them aligned
by holding them.
• To avoid skipped teeth, do not rotate crankshaft and cam-
shaft until front cover is installed.
