The TEMS-1 “Vostok” tachograph is installed on the instrument panel and is designed to indicate and record vehicle operating parameters and driver operating modes (drivers during two-shift work)

During daily maintenance, we drain the condensate from the system receivers after the trip.

Condensate should be drained from the receivers at the nominal air pressure in the system, moving the drain cock rod to the side

Installing the cylinder block on the engine assembly stand

Assemble and prepare the piston group

Cylinder head gaskets are replaced when coolant and oil leaks appear at the junction of the cylinder head with the cylinder block.

Lapping valves and replacing oil seals of the cylinder head of the 740 Kamaz diesel engine

If the valve does not fit tightly on the seat, then gaps are formed in some areas of the valve and seat

The scope of maintenance includes control and diagnostic, fastening, lubrication, adjustment, electrical and assembly-disassembly work related to the testing and adjustment of individual units and assemblies on special stands and equipment

The pre-heater is designed to warm up a cold engine and automatically maintain the thermal state of the engine and cabin, regardless of the operation of the diesel engine

Adjusting the tension of the generator drive belts and water pump of the YaMZ-236M2, YaMZ-238M2 engines

Tools and accessories will be required: a 13 and 17 wrench, a mounting blade and a device for checking the tension of drive belts, a 17 socket wrench

Crank mechanism of KAMAZ engines 740.11-240, 740.13-260, 740.14-300, 740.11-3902007 RE:

The crankshaft is made of high-quality steel and has five main and four connecting rod journals, hardened by high-frequency current, which are connected to each other by cheeks and mated with them by transition fillets

The valve timing mechanism is designed to ensure the intake of fresh air into the cylinders and the exhaust of exhaust gases from them

Turbochargers of diesel engines KAMAZ 740.11-240, 740.13-260, 740.14-300

The gas turbine supercharging system, by using part of the energy of the exhaust gases, provides the supply of pre-compressed air to the engine cylinders

The engine cooling system is liquid, closed type, with forced circulation of coolant

The main elements of the system are the water pump, fan, fan drive fluid coupling, thermostats, fluid coupling switch, radiator, fan casing, water pipes, radiator louvers and expansion tank with a vapor-air lock.

The fuel supply system ensures fuel purification and uniform distribution among the engine cylinders in metered portions and at strictly defined moments in time

Removing the high-pressure fuel pump

To remove the high-pressure fuel pump:

Repairing the water pump

To remove and disassemble the water pump:

For disassembly, it is recommended to use the P-770 rotary stand, on which the engine can rotate around the vertical and horizontal axis

After repairing engine assemblies or replacing them, run the engine on a stand equipped in accordance with the requirements of GOST 14846-81, in one of the modes below, depending on the replaced parts:

Combined lubrication system with "wet" sump
