Gamshaft Inspection
NOTE: Do not rotate the camshaft during inspection.
1. Remove the rocker arm assembly (see page 6-26).
and disassemble it (see page 6-27).
2. Put the rocker shaft holders, camshaft, and
camshaft holders on the cylinder head, then tighten
the bolts to the specified torque.
Specified torque:
I mm bolis:
22 N.m {2.2 kgt m, 16lbf.ft}
6 mm bolts:
12 N.m {1.2 kgf.m,8.7 tbf.ftl

3. Seat the camshaft by pushing it away from the
camshaft pulley end ofthe cylinder head.
4. Zero the dial indicator against the end of the
camshaft, then push the camshaft back and forth
and read the end play. lf the end play is beyond the
service limit, replace the camshaft head and
recheck. lf it is still beyond the service limit, replace
the cylinder.

Valve Stem-to-Guide Clearance\
Inspection
1.Remove the valves (see page 6-3'1).
Slide the valve out of its guide about 10 mm. then
measure the guide-to-stem clearance with a dial
indicator while rocking the stem in the direction of
normal thrust (wobble method).. lf the measurement exceedsthe service limit,
recheck it using a new valve.. lf the measurement is nowwithin the service
limit, reassemble using a new valve.. lf the measurementwith a newvalve still
exceeds the service limit, go to step 3.
lntake Valve Stem-to-Guide Clearance:
Standard lNew): 0.06 0.11 mm

Service Limit: 0.22 mm 10.009 in.)
Subtract the O.D. of the valve stem. measured with
a micrometer, from the LD. of the valve guide,
measured with an inside micrometer or ball gauge.
Take the measurements in three places along the
valve stem and three places inside the valve guide.
The difference between the largest guide
measurement and the smallest stem measurement
should not exceed the service limit

Connecting Rod and Crankshaft End Play Inspection
1.Remove the oil pump (see page 8-9).
Remove the baffle plates (see step 6 on page 1 -12).
3. Measure the connecting rod end play with a feeler
gauge between the connecting rod and crankshaft.

Standard {New): 0.15 0.30 mm(0.006-0.012 in.l
Service Limit 0.40 mm (0.016 in.l
4.lf the connecting rod end play is out-of-tolerance,
install a new connecting rod, and recheck. lf it is
still out-of-tolerance, replace the crankshaft (see
page 7 -12],.
5. lnstall a dial indicator as shown. Push the
crankshaft firmly away from the dial indicator, and
zero the dial against the end of the crankshaft. Then
pull the crankshaft firmly back toward the indicator;
the dial reading should not exceed the service limit.

lf the end play is out-of-tolerance, replace the thrust
washers and recheck. lf it is still out-of-tolerance,
replace the crankshaft.
