The steering includes a steering mechanism 10 (Fig. 1) with a built-in distributor, a column 2, a steering wheel 1, a power cylinder 9, a pump 3, an oil tank 4, and hoses.
The electrical power system of automobiles consists of two sources: batteries and an alternating current generator set.
In addition, the system includes a number of intermediate relays, a battery mass switch and a key switch for instruments and starter
Operating principle of Common Rail Sistem 2
Battery-type fuel system - Commonrailsistem 2 (SEZ2) with electronic fuel supply control manufactured by Robert Bosch (Germany).
The vehicles are equipped with service, parking, spare and auxiliary brake systems, as well as devices for connecting the brake system of a semi-trailer with a two-wire pneumatic drive and outputs for supplying other consumers with compressed air
When vehicles are equipped with air suspension, an electronic control system of the ECAS type (by Wabco) is installed
Cars can be equipped with a 4-channel anti-lock braking system (ABS) of type 4S/4M (4 sensors/4 modulators) with a microprocessor control unit. Wabco (Germany) or BPO "Ekran" (Belarus)
The MAZ-64227, MAZ-54322 vehicles are equipped with an eight-speed dual-range YaMZ-238A gearbox with synchronizers in all gears except reverse
Let's consider assembling a diesel engine in a certain sequence, taking into account that our parts and assemblies are previously pre-assembled and tested
Brake mechanisms are drum type with two internal pads and an easily removable brake drum
On MAZ vehicles with engines from the Yaroslavl Motor Plant (YaMZ), the following generator sets (GS) are installed: G273V1 - 45 A, 1312.3771 - 50 A, 6582.3701 - 80 A and 3112.3771 - 80 A
The engine cooling system (Fig. 1) is liquid, closed type, with forced circulation of coolant
To diagnose the YaMZ-650 engine, you need diagnostic equipment from BOSCH of the KTS family (KTS 530/540/570), shown in Fig. 1
The clutch of the YaMZ-238 model is double-disc, dry, friction type, with a peripheral arrangement of cylindrical springs
Installing cylinder heads, valve rocker arms and adjusting valve clearances
The cylinder head mounting studs are screwed into the right and left rows of the cylinder block, having previously lubricated the threaded holes for the studs in the block with diesel oil
The electrical system of the MAZ car has a rated voltage of 24 V. The vehicle's on-board network is made according to a single-wire circuit
Removing the camshaft
Remove the axial lock of the camshaft (650.1006236) by unscrewing 2 screws securing it (310145)
Adjusting the central gearbox
Adjust with the gearbox removed in the following sequence:
The use of contaminated oils is not allowed.
It is not allowed to engage the gear in the main box until the selected range of the demultiplier turns on, that is, until the control lamp lights up when the slow range is turned on or until it goes out when the fast range is turned on
The gearbox of the MAZ-5335 car and its modifications during repair are disassembled in three stages: partial disassembly, general disassembly of units
