1. OIL SEAL
• A front crankshaft oil seal is press-fit into the
case.
2. TIMING CHAIN CASE
• The engine support bracket, the oil pump and the
relief valve are integrated as well as water cham-
ber of the water pump.
3. TIMING CHAIN
• The two camshafts are driven by the timing chain
via the respective sprockets. The timing chain,
consisting of 180 links, is an endless chain, con-
necting the crankshaft sprocket with the camshaft
and V.V.T. sprockets. The timing chain is
equipped with three mark link plates (blue) to cor-
rectly time the two sprockets with each other. The
timing chain is tensioned by the timing chain ten-
sioner, which has a built-in plunger with plunger
springs.

4. TIMING CHAIN TENSIONER
• The plunger in the timing chain tensioner directly
pushes the tension lever, and the pressure auto-
matically adjusts the timing chain tension. A cam
is provided to lock the plunger in place after the
engine stops. This helps prevent the timing chain
from wobbling just after the engine starts. With
the timing chain tensioner installed, do not crank
the engine in the reverse direction. This will force
the plunger to overcome the cam, or even cause
other problems.
