Disconnect the battery terminals
Using a 27 wrench, unscrew the drain plug and drain the oil from the engine crankcase. Putting the plug in place
We replace the oil seal when oil leaks from the rear of the engine, when the clutch discs become oily, and when repairing the engine
Disassembling the diesel engine of a KamAZ-740.10
Before disassembling the diesel engine must be cleaned of dirt and oil, washed with kerosene or a degreasing solution
The coolant pump is being repaired due to coolant leakage from the inspection hole
For tightening with particularly high precision (assembly of engine units, important building structures), use pointer wrenches; for quick assembly with the required tightening torque (tightening anchor bolts, tightening bolts during tire fitting), use limit type wrenches
Purpose, design and operation of the EFU
The device is designed to facilitate starting a cold engine at air temperatures down to -25 °C, quickly return the engine to normal temperature conditions and reduce smoke that occurs in a cold engine.
The power supply system (Fig. 1) serves to power consumers when the engine is running
The control and measuring instrument system (Fig. 1) is designed to monitor the operating mode of units and individual assembly units of the vehicle, as well as to determine the speed of movement
The light signaling system (Fig. 1) is designed to notify drivers of other vehicles about a turn (U-turn) or braking, as well as to signal the state of vehicle assembly units that affect traffic safety
The external and internal lighting system (Fig. 1) is designed to ensure vehicle safety, as well as illumination of the driver’s workplace
Analysis of failures in the power supply system
The main causes of failures in the power supply system are:
The engine starting system of a KamAZ vehicle can be in three alternative states: serviceable, operational and faulty (failure)
Analysis of circuit diagrams of lighting systems, light and sound alarms allows us to draw the following conclusions: - the circuits have general and private branches;
The heating and ventilation system is designed to maintain optimal temperature conditions in the cabin when the ambient temperature changes
The windshield cleaning system is designed to wash and clean windshields to ensure vehicle safety
The following pre-heater failures may occur on a KamAZ vehicle:
- - the electric motor of the pump unit does not work;
When the auxiliary brake valve button is pressed, the engine does not stop, the flaps in the exhaust pipes do not turn, the trailer does not brake
In this article we will consider the pneumatic drive of trailer brakes, i.e. the interaction and malfunctions of devices installed on the tractor and on the trailer
To diagnose the pneumatic drive of brake systems, you must have at least one control pressure gauge and use the control outlet valves available on the vehicle
On KamAZ-5320 vehicles, air enters the emergency brake release circuit (Fig. 1) with the engine running directly from the compressor through triple safety valve 13
