Servicing the Spark Plug
Service Interval: Yearly. Service the spark plug
and replace it if necessary.
1.
Stop the engine and wait for all moving
parts to stop.
2.
Disconnect the wire from the spark plug.
3.
Clean around the spark plug.
4.
Remove the spark plug from the cylinder head.
Important: Replace a cracked, damaged,
or dirty spark plug. Do not clean the
electrodes because grit entering the
cylinder can damage the engine.
5.
Set the gap on the plug to 0.030 inch
(0.76mm) (Figure 21).
6.
Install the spark plug and torque it to
20–22ft-lb (27–30 N-m).
7.
Connect the wire to the spark plug.
Replacing the Drive Belt
If drive belt becomes worn, oil-soaked, excessively
cracked, frayed, or otherwise damaged, replace it.
1.
Remove the 4 bolts that hold the drive belt
cover (Figure 22) in place.
Note
: The transmission belt cover is fixed by
two small bolts, one nut, two tapping screws
and a piece of reinforced plate.
2.
Remove the belt from the rotor pulley.
3.
Press down on the idler arm and remove the
belt from between the tab on the idler arm
brake and the rotor pulley.
Note
: The engine pulley belt guide is very
close to the pulley, and the belt may not fit
through the gap.
4.
Twist the belt out in front of the belt guide so
that the belt is wedged between the belt
guide and the engine pulley.
5.
Insert a screw driver into the hole in the belt
guide as shown in Figure 23, and flex the
belt guide toward the rotor pulley enough to
pull the belt through the gap.
Note
: Take care not to distort or damage the
belt guide.
6.
To install the new drive belt, reverse the
steps above.
Important: Ensure that you install the
drive belt so that it sits above the two
tabs on the idler arm and below the idler
arm brake.
(Figure 24).
7.
Install the drive belt cover with the
fasteners that you removed in step 1.
