Valve Adjustment
1. Move the piston in the compression stroke until it's
at Top Dead Center (TDC).
2. Loosen the locknuts of the valve adjustment
screws and drive a 0.2 mm (0.78 in.) feeler gage
between the upper surface of the valve stem and
the rocker arm. See Figure 10-94.
3. Adjust the clearance until a slight drag is felt on the
feeler gage when turning the valve adjustment
screws with a screwdriver.
4. Hold the valve adjustment screws and tighten the
locknuts.
5. Recheck the clearance.

Fuel Injector
1. Replace the washer located under the injector and
in the seat of the cylinder head.
Note: Use only a gasket under the injector and ensure
that the old gasket is removed.
2. Install the injector and the clamp.
3. Tighten the injector nuts at the specified torque.
See Section 1.5.
Injection Pump and Speed Control Shaft
Connection
1. Keep the accelerator lever in the higher position.
2. Pull down the fuel excess start device's button.
Note: As the inner return spring pushes the control
lever, it goes towards the timing gear cover and
stops against it.
3. Set the pin of the fuel injection pump in the
higher-fuel supply position (towards the right, front
fuel pump view).
4. Guide the injection pump in the timing gear cover
and ensure that its pin is in the yoke of the control
lever's arm.
5. Reinstall the injection pump using the same
number and type of shims.
Note: Before installing the shims, put the paper gasket
on the cover because a direct contact does not
permit adequate sealing.
