Diesel Engines — Timing Belt Replacement
Figure 291 shows the timing drive components, the drawing can be used when replacing or removing components. The timing belt should be replaced every 100,000 km. At this point, it has reached its normal service life....

Cylinder head — removal and installation
Below is a description of the removal and installation of the cylinder head without removing the engine. Figure 29 shows an assembly drawing of the cylinder head with some parts that need to be removed when removing the...

Disassembling the cylinder head
Clamp the cylinder head in a vice using the clamp attached to one of the exhaust manifold studs. Remove the camshaft. Loosen the bearing cap bolts crosswise from the edges to the middle and remove the caps To remove and...

Cylinder head overhaul
Check all cylinder head parts for wear. Clean cylinder head surfaces (to remove the remains of the old seal, use a scraper without scratching the cylinder head material). Checks and controls shall be carried out in...

Cylinder head assembly
Clean all cylinder head parts and lay them out on the workbench so that they are in the order of assembly. If the valves have been ground in, they must be installed in the corresponding seats, since the grinding pattern...

Installing the cylinder head
Place the new head gasket on the cylinder block. Make sure that the front side of the gasket is aligned with the front side of the engine. Both pins should go through the gasket. Check that the pin on the end of the...

Checking and adjusting valve clearances
On diesel engines, valve clearances are checked and adjusted on a cold engine. Remove the cylinder head cover. Check the valve clearances as follows: Turn the engine until the piston of the first cylinder is set to the...

Checking cylinder compression
If you suspect that a cylinder has low compression, you should check it in individual cylinders using a compression meter. This is more difficult to do on a diesel engine, since an adapter is required that is screwed in...

Pistons and connecting rods — removal and disassembly
The parts of the crank mechanism together with the pistons and connecting rods are shown in Figure 313. To remove the pistons and connecting rods, it is necessary to remove the cylinder head and oil pan (as well as an...

Measuring cylinders
To measure the cylinders, a cylindrical dial indicator (Fig. 89) is required, which can be used to measure in the middle and at the bottom of the cylinder. If the dial indicator is missing, the following work cannot be...

Assembly of pistons and connecting rods
When assembling pistons and connecting rods, observe the following instructions: Arrow on the piston bottom (either applied or on a new connecting rod with an arrow) must face the front of the engine. The "VORN" mark on...

Installing pistons and connecting rods
Lubricate the cylinder bore. Lay out all connecting rods by cylinder numbers. The "VORN" mark on the connecting rod and on the piston crown should be directed towards the engine pulleys. Distribute the piston ring...

Crankshaft and flywheel
Work on the crankshaft and related parts in the same way as was done for gasoline engines. In this case, work should be done using the table of dimensions and adjustments, since it contains different data regarding...

Engine cooling system
Everything that has been described for petrol engines also applies generally to diesel engines. Therefore, this chapter only concerns the differences in the removal and installation of certain parts. This applies, for...

Removal and installation the water pump
Removal and installation of the water pump is explained in Figure 316. In addition to the toothed belt, it is also necessary to remove the high-pressure fuel pump to provide access to the water pump. The following work...

Engine thermostat
The thermostat is located in the inlet fitting of the cooling system, i.e. before removing the thermostat, the coolant should be drained to a height below the fitting. The thermostat is checked in the same way as on a...

Engine lubrication system
The lubrication system is supplied with a centrifugal pump. The pump design is shown in Figure 317. Fig. 317. Assembly drawing of the oil pump. 1. Drive gear; 2. Oil pump; 3. Pressure reducing valve; 4. Spring; 5....

Removal, overhaul and installation of the oil pump
To access the pump, remove the toothed belt, idler pulley and crankshaft gear. Also remove the oil pan. The oil pump is bolted to the front of the engine and sealed with a sealing ring. The mounting bolts are of...

Checking the engine oil level
The description of operation given for gasoline engines also applies to diesel engines. Special oils are used for filling a diesel engine.

Diesel fuel injection device
Cleanliness is a prerequisite for all work on a diesel engine. It is imperative to clean the union nuts of the pressure pipe before unscrewing them. The high-pressure fuel pump cannot be disassembled or repaired. and is...

Precautions when working with the injection device
When carrying out any repair work on the injection device, regardless of its volume, maintain cleanliness. The following points should be especially taken into account: All work with the injection device must be carried...

Operating a vehicle on diesel fuel
At certain temperatures, crystals form in diesel fuel, which thicken the fuel so much that it cannot pass through the filter. To prevent these malfunctions, petrol stations sell fuel that corresponds to a certain time...

Diesel engine fuel filter
The fuel filter is replaced in accordance with the instructions in the operating manual and must be replaced if the filter warning light comes on, indicating that there is water in the filter. Disconnect the connector...

High pressure fuel pump
Removal and installation. If a new high-pressure fuel pump is installed, all parts of the injection device should be checked. Drain the fluid from the cooling system. Disconnect the throttle cable from the high pressure...

Injectors — removal and installation
For crimping or for repairing the injector! should be given to a diesel engine workshop. Do not do this work yourself under any circumstances, since in addition to the need for a special tool, the injection pressure can...

Glow plugs
The only ignition-related parts are the glow plugs, which are used to initially heat the combustion mixture. The glow plugs are energized after the ignition key is set to the glow position. The supply voltage is at...

Adjusting the idle speed
The idle speed adjustment is 100% perfect if the amount of fuel injected at idle speed is adjusted. This adjustment can only be made using special devices. However, general control and temporary adjustment to ensure...

Adjusting maximum speed
Maximum speed is set at the factory and should not be altered. Like idle speed, maximum speed is controlled by the amount of fuel injected. This adjustment requires special equipment. Figure 323 shows where the...
