• Timer (which shows the time that has been
accumulated since the start of timer measure-
ment)
• Tripmeter (which shows the accumulated travel distance in timer measurement)
• Change tripmeter digits (capable of change to
any given ones)

c. Install the dowel pins and the camshaft caps.
TIP
• Tighten the camshaft cap bolts in a crisscross pattern from innermost to outer caps.
• Do not turn the camshaft when measuring the
camshaft journal-to-camshaft cap clearance.
d. Remove the camshaft caps and then mea- sure the width of the Plastigauge® “1”.

SHAFT SPROCKET
1. Check: • Timing chain “1”
Damage/stiffness  Replace the timing
chain and camshaft as a set. 2. Check:
• Camshaft sprocketMore than 1/4 tooth wear “a”  Replace the
camshaft and the timing chain as a set.

a. While pressing the tensioner rod lightly with
your fingers, use a thin screwdriver “1” to
wind the tensioner rod up fully clockwise.
b. When releasing the screwdriver by pressing lightly with your fingers, make sure that the
tensioner rod will come out smoothly.
c. If not, replace the tensioner assembly.
