Foreword This Workshop Manual covers the latest technical developments according to month/year indicated on each page. It has been written in such a way, that it contains all dismantling and assembly instructions in accordance with the table of contents, including all required data etc., so as to permit a trained mechanic to carry out correct and professional repairs.

We have not included information such as cleaning parts, replacing of "O" Rings, gaskets, oil seals etc. since it is assumed, of course, that the mechanic will be aware of the necessity of carrying out such work.

Use only the tools prescribed or absolutely identical tools when carrying out work of whatever nature.

It has been assumed that a standard set of workshop tools is available.

Please refer to the instruction book for maintenance work, operating materials and trouble shooting information.

Use only GENUINE HATZ PARTS for repairs!

Only these parts guarantee perfect dimensional accuracy and quality.

For the rest, please observe the general legal regulations and the regulations of the responsible professional associations.

Discrepancies may occur between the described features and actual features owing to special equipment, and it has not been possible to allow for such discrepancies either in the Workshop Manual or in the spare parts list.

Draw out the pump nozzle unit or release it with a suitable impact extractior .

In order to release the pump nozzle on the control side, the fuel return pipe must be removed.

To do this, release the clamp and draw the pipe out of the connecting element. The remainder of the dismantling procedure is as described earlier.

NOTE: Take care to ensure that no seals remain in the cylinder head.

Installing the unit injector NOTE: In principle, all seals and O-rings are to be replaced.

Hook the connecting rod and draw it up into the hole in the regulating sleeve.

Place the unit injector in the cylinder head and press it in as far as the stop.

Place the retaining bar in position and tighten it slightly (pay attention to the installation position; the radius points towards the pump nozzle).

Use the checking device 645 879 00 to ensure the radial direction of the pump nozzle is correct.

Tighten the retaining bar with a torque wrench to 9.5 Nm.

Place the fuel delivery line in position and push it into the unit injector as far as the stop collar.

In principle, replace the O-rings and apply some grease in order for them to be fitted more easily.

After all the unit injectors have been fitted, introduce the delivery lines to a uniform depth into each unit injector. If this is not done, the individual locking elements cannot be set in place on top.

Fix the fuel pipes in place with the securing clamps.

Always replace the sealing rings on the return line and take care when fitting them that the securing ring is located in the groove.

Push the return line in as far as the stop and secure it with clamps.

Introduce the fuel pipe into the connection nipple and tighten the nipple.

Subject the fuel system to 5 bar of pressure for about 2-3 minutes with the high-pressure pump 632 913 00 in order to test the sealing tightness of the internal fuel lines.

Fit the fuel lines for delivery and return, taking care in the process to ensure that the choke is in the correct position in the return line.

Plug the regulator unit into position with the special tool 643 649 00.

Release the regulator arm.

Suspend the connecting rod into the lowest hole.

Align the connecting rod at right angles to the regulating sleeve and the regulating shaft.

Press the connecting rod in the direction unit injector, in order to compensate for any play in the moving parts, and secure the regulating arm.

Repeat the procedure with all the pump nozzle units.

Take out the alignment pin.

Screw the blocking screw of the regulating sleeve at the unit injectors as far as the stop.

Fit the rocker arm to the valve control. Adjust the valve play to 0.10 mm. The valve play is adjusted on the base circle of the camshaft. Adjust the valve play with the adjustment nut and then fix it with the counter-screw.

Note the correction value of the unit injector. In this situation, pay particular attention to the sign + or -. If there is no sign, the value is to be noted as a - value.

When fitting the rocker arm units to the unit injectors, make sure that the outer units are provided with support for the bearing covers.

Connect the rocker arm and the pump plunger with the securing clamp.

Lower the rocker arm in the mounting and rotate the eccentric shaft in such a way that the adjustment hole is pointing upwards.

Place the bearing covers in position in such a way that the contact surfaces on all bearing covers point in the same direction. Tighten the nuts by hand.

Push the rocker arm shaft in the axial direction until the clamps for the pump piston are located centrally to the rocker arm and can be moved without friction resistance.

Apply preliminary tension to the bearing covers on the side with the contact surfaces as far as the stop, and tighten the opposite side sufficiently for the shaft still to rotate easily.

Hook the leg spring at the bearing bolt of the rocker arm into position and apply preliminary tension with the fitting tool 641 063 00.

Adjusting the start of delivery

Turn the engine over in the direction of rotation until the roller of the injection rocker arm is located in about the middle of the tangent.

In this position, the scaling of the flywheel is already visible in the viewing hole, which is provided for this cylinder. Now rotate the crankshaft further until the specified setting value coincides with the marking at the viewing hole.

The setting value for the start of delivery is specific to the engine, and is therefore to be taken from the rating plate or the injection pump setting value table.

+ Set the measuring gauge on the calibration device to a freely chosen pre-tension value. It is recommended that the gauge be set to three millimetres, in order to avoid possible contact between the gauge and engine components.

Carefully place the measuring gauge with the prism above the roller of the rocker arm and take care to ensure that the measuring tip is lying in the dome of the cover of the pump nozzle unit. By applying slight impact movements to the engine housing, the measuring gauge will now oscillate to a stable value.

The first aim of the adjustment is to set the same value in the engine as on the calibration device (0 position). To do this, rotate the eccentric shaft with a suitable mandrel.

–

All pump nozzle units are pre-calibrated and provided with individual correction values. This value, in hundredths of millimetres, is engraved on the cover of the pump nozzle unit. The figures express the missing stroke of the pump piston until the suction hole begins to wear. In this context, pay particular attention to the sign + or -. If there is no sign present, the value is to be noted as a - value.

By rotating the eccentric shaft further, set the measuring gauge in accordance with the sign to the correction value.

Tighten the bearing covers with a torque wrench.

Tightening torque: 9 + 1 Nm In this situation, account must be taken of the fact that the pre-set value will change again.

This needs to be borne in mind when adjusting the correction value. Deviations in the correction value by +/- five hundredths of a millimetre are permissible.

3. Adjusting the length of the carburet throttle control: Move the carburet throttle controls to the lower stop (HATZ).

The carburet must be approximately 1/2 ball shaped head shorter (compared to the ball mounted at the SM).

4. Move the SM to “Position up” by pressing V.

5. Move the carburet throttle control (HATZ) to the full-load stop manually to check the carburet length. The carburet should now protrude the ball mounted on the SM about ½ ball shaped head.

6. Now move the SM to „Position middle“ by pressing W. Fit the carburet to the SM and secure it.
