The gas distribution mechanism controls the timely intake of air charge into the cylinders and the removal of exhaust gases from them; consists of valves with springs, a camshaft with gears and parts that transmit movement from the shaft to the valves
Design and operation of Kamaz parking (spare) brake devices
The parking brake is designed to hold a stationary vehicle on a horizontal section, path or slope specified by the rules of the road
Axial-type fan, five-bladed, creates additional air flow through the core of the radiator of the cooling system
It is mounted on the hub 15 of the driven shaft of the fluid coupling and placed in a casing
The clearance in the valve mechanism must ensure a tight fit of the valve to the seat when the rod elongates due to heating and in the event of the head settling in the seat due to wear of the chamfers
Malfunctions of pneumatic drive power supplies
When servicing the pneumatic drive of the car brakes, you must first of all make sure that the system is tight
KAMAZ platform lift limiting valve
The platform lift limiting valve is secured to the bracket of the first subframe crossmember.
A bushing with a sealing ring is screwed into the housing 16
Electro-pneumatic valves serve to distribute compressed air through the pneumatic actuating chambers of the power take-off and control valve
The locking device, designed to connect the hydraulic system of the KamAZ-55102 dump truck-tractor with the hydraulic system of the trailer, consists of two buildings 1 and 7, one of which is connected to the discharge line of the tractor, the other - to the trailer.
When maintaining the hydraulic system, you should check the oil level in the tank with the platform lowered using the indicator built into the tank cover.
The level should be between the “H” and “B” marks on the indicator
KAMAZ car winch
The winch is designed for self-pulling and pulling cars and trailers through difficult areas
Centralized system for regulating air pressure in Kamaz tires
The tire pressure regulation system is used on KamAZ-4310 vehicles and is designed to increase the vehicle's cross-country ability on difficult sections of the road by changing the air pressure in the tires
The mechanical all-mode direct-acting speed controller with an overdrive gear for the load drive is designed to maintain the engine speed mode set by the driver by automatically changing the amount of fuel supplied depending on the load change
To remove the generator, disconnect the battery mass, raise the cab of the KamAZ vehicle and disconnect the terminals “+”, “—”, B
The engine cooling system is liquid, closed type, with forced circulation of coolant
During operation, there are cases when a liner crack occurs
Air coming out of the valve during braking is discharged to the outside through the air duct connected to the atmospheric outlet (II)
The triple safety valve (Fig. 1) performs the following functions:
- - divides the air line coming from the compressor into two main and one additional circuit;
Secure the regulator in a vice with soft jaws by the boss of terminal 1 of housing 5.
Do not secure the regulator by the upper or lower part of housing 5, as this may result in its deformation or destruction.
Removing and installing the gearbox of a KamAZ vehicle
The gearbox is removed to replace and repair the clutch and repair the gearbox
Two compression rings and one oil scraper ring are installed on the piston
Compression rings are designed to prevent gases from escaping into the crankcase during compression and expansion
