Refueling volumes of the mini loader MKSM 800
Technical description of units
The travel drive of the MKSM 800 mini loader is provided by a transmission with a Zetor 5201 diesel engine, which is rigidly connected to the pump drive and to the NPA 33 movement pumps and the U32l working equipment pump. ... The oil cooler of the hydraulic system and the radiator of the cooling system of the skid steer are located in front of the engine. The fuel tank is located on the right side, the hydraulic tank on the left side in the inner frame. The RSK16T3 distributor is located in front of the NPA 33 variable pumps under the hydraulic filter of the working fluid. To provide convenient access to individual units of the MKSM 800 loader, the safe type cab is tilted after preliminary disconnection of the hinges in the loader cab. The cab contains all controls and controls, instrumentation and the operator's seat. All this together forms a single assembly unit. The loader wheels are attached to final drives, which are fixed on opposite sides of the loader frame. Heating is located on the left side of the cab from the inside. The batteries are located on the right and left fenders. Access to them is possible after lifting the covers, which are equipped with a motorcycle lock.
Mini loader MKSM 800 is equipped with a Zetor 5201 diesel engine, which is elasticly installed. The engine is accessible from the rear after lifting the rear radiator shroud and from the top after tipping the bonnet and cab. It is a direct injection, four-stroke, three-cylinder, water-cooled diesel engine. The crankshaft housing is cast from gray cast iron, one-piece, with a flange for mounting the pump drive. The cylinder head is independent for each cylinder, the cylinder liners are replaceable.
The engine cooling system is liquid with forced circulation and with a thermostat. The circulating pressure lubrication system with a wet bath, the MKSM loader is equipped with a two-stage or replaceable oil filter. The fuel delivery system consists of a fuel pump, a mechanical all-speed regulator, and a fuel priming pump. The Zetor 5201 engine is cooled with a forced circulation liquid provided by a centrifugal pump mounted on the front of the engine crankcase and driven through a water pump via a V-belt drive. The cooling system includes a small circuit with a thermostat that quickly heats up the motor to an operating temperature of up to 80 degrees. The filler cap is located on top of the radiator, the coolant drain cock is located on the bottom left side of the radiator. The power supply system of the MKSM loader consists of a fuel tank, a fuel supply system on the engine and fuel pipes. The fuel tank is located on the right side of the rear with a filler neck behind the cab. The fuel tank has a capacity of 55 liters. From the bottom of the tank, fuel is sucked in by the fuel priming pump through the fuel line. A coarse fuel filter is installed on the lower part of the fuel priming pump. From the fuel priming pump, diesel is pumped into the Motorpal fuel pump through a single-stage fuel filter. The fuel pump delivers fuel through the high pressure pipes to the injectors. Excess fuel from the engine injectors flows back to the fuel tank via the return line.
MKSM 800 loader hydraulic system
Serves to drive the working equipment and the running gear. It consists of two hydraulic circuits: the implement circuit and the trolley drive circuit.
MKSM 800 working equipment contour
Consists of U32l pump, RSK16T3 three-section distributor, two hydraulic cylinders for raising and lowering the boom and two hydraulic cylinders for opening and closing the bucket. This circuit is protected by a pressure of 16 MPa at an engine speed of 1500 rpm by a safety valve on the RSK16T3 distributor.
MKSM 800 stroke drive circuit
Consists of two hydraulic pumps NPA 33 and two hydraulic motors MPA 33. This circuit is protected by a pressure of 35 MPa by means of high pressure safety valves built into the MPA 33 hydraulic motors. The working fluid tank, radiator and filter are common to both circuits. The hydraulic tank has a capacity of 55 liters.
Pump drive MKSM 800
Serves for the transmission of torque from the engine through the clutch to the adjustable pumps NPA 33, which ensure the movement of the loader by means of hydraulic motors MPA 33, as well as to the gear pump U32L, which serves to power the hydraulic cylinders of the working equipment.
The pump drive consists of a power take-off and a clutch, which together form one unit.
Controlling the pump drive is reduced to disconnecting it from the engine, especially to facilitate starting the engine at lower temperatures. This operation is performed mechanically with the clutch pedal located in the operator's cab.
The MKSM 800 loader drive is hydrostatic. The power unit is a Zetor 5201 diesel engine, the power of which provides optimal dynamic parameters of the loader during operation. The torque from the engine is transmitted through the flywheel and the clutch to the pump drive. The clutch is single-disc, disengaged with a pedal in the operator's cab. It serves to disconnect the pump drive in order to facilitate engine starting.
The pump drive crankcase is equipped with flanges for fastening two adjustable pumps NPA 33, which provide a drive for the chassis, and one gear pump U 32l, which fills the hydraulic system of the working equipment. From the adjustable hydraulic pumps, the torque is transmitted hydrostatically to the MPA 33 hydraulic motors by means of high pressure hoses. From the hydraulic motor, the torque is transmitted to the final drives by means of gears that are located between the hydraulic motors and the final drives. The design of the gear assembly allows the loader to be braked by the force of the Belleville springs. The loader is braked by means of a safety lever that is mechanically connected to the parking brake bypass valve when the safety ramp is folded back. The bypass valve allows pressurized oil into the drain branch of the hydraulic system (which releases the loader), causing the loader to brake. The raised safety arm protects against spontaneous or uncontrolled movement of the MKSM 800 loader.
MKSM 800 loader control
The control of the MKSM 800 loader differs structurally from the loaders produced at the present time. One-handed movement control - with the left hand, control of the working equipment, including the bucket, is carried out with the right hand.
Attention! When learning to operate the MKSM 800 loader, the levers and handles must be moved carefully. The clutch may only be used when starting the engine in cold weather, while the clutch can be depressed for a maximum of 1 minute. Never use the clutch while the engine is running. In this case, it threatens the destruction of the clutch with the bearing.
Starting the engine at low temperatures.
When operating the MKSM 800 loader in winter conditions, it is very important to change the oil and oil filter at the intervals recommended by the manufacturer, since it may happen that the viscosity of the oil increases during operation. Thus, the thickened oil flows around the engine oil filter when starting the engine, which ultimately means that the oil enters the engine without filtration. As a result, engine wear increases several times.
A prerequisite for starting the engine at temperatures below -5 is to replace the oil with 10W30, the cooling system must contain a liquid with a freezing point of -25 degrees. The hydraulic system must be filled with VMGZ oil.
It is recommended to build an electric antifreeze heater into the motor block on an external 220V power source, which preheats the coolant to a temperature that meets the summer operating conditions of the MKSM loader. It is recommended to turn on the dipped beam for a short time before starting. It is imperative to squeeze the clutches to disengage the hydraulic pumps and the pump drive.

Scope of application of multipurpose municipal construction machines MKSM
Extremely wide: from small areas to industrial zones. The design features of these machines allow you to smoothly change their speed and direction of movement, turn around their own axis. The MKSM are most in demand in construction organizations, housing and communal services, road facilities, industry and transport. The popularity of this technique is explained by its combination of its versatility, which makes it possible to mechanize almost all communal, transport, construction, loading and earthmoving operations, its compactness and high maneuverability, which makes it possible to organize work in cramped conditions (in narrow aisles, enclosed spaces, in yard areas), where overall restrictions make the use of conventional techniques impossible.
The overall dimensions of the MKSM make it possible to penetrate even into openings 2.1 m high and 1.8 m wide. MKSM is ideal for the maintenance of sidewalks, footpaths, alleys, markets, when laying communications, road maintenance and landscaping.
In addition, the temperature range of MKSM operation is from -40 to +45, satisfying the needs of consumers in all climatic zones of Russia. MKSM models are equipped with modern diesel engines that meet European environmental standards. With regard to all manufactured modifications of the MKSM, the basic principle remains - to ensure maximum versatility of equipment, i.e. applicability in all major market segments, including by maintaining a wide range of quick-detachable attachments.
At the request of consumers, a set of attachments is supplied to MKSM: for loading (various buckets, forks and other equipment), cleaning (brush, blade, snowplow, etc.), earthmoving (drilling, excavator equipment), construction (concrete mixer) and others. works, including on soils with a low bearing capacity (in the case of installing a set of metal tracks on the MKSM, increasing the traction and coupling properties of the machine).
At the same time, it takes a little time to replace the working equipment - the equipment is equipped with a quick-acting clamp, which allows the operator to change equipment independently and without the use of additional tools.

The MKSM-800 loader is a multipurpose special equipment that is used in warehouses, construction works, and public utilities. The functionality of the loader depends on the attachment.
Despite its enormous capabilities, MKSM-800 has a small size, which allows the loader to be moved from site to site by truck and ensures uninterrupted operation in narrow aisles of warehouses. The loader can enter the room through a gate measuring 2.1 meters in height and 1.8 meters, and a volumetric hydraulic drive, which makes it possible to independently steplessly change the rotation speed of the right and left gearboxes, can turn the MKSM-800 on the spot, which makes it an excellent assistant when work in a warehouse.
The designers have done everything for the comfort of the driver. So in the cabin of the loader there are two hangers for outerwear, a box with the necessary tools, and the presence of vents, heating and thermal insulation will maintain a favorable temperature regime in any weather. All the main nodes of the MKSM-800 are located in easily accessible places. For example, if it is necessary to prevent or inspect the engine, it is enough just to open the rear hood, and for the same actions with the hydraulic system, it is enough just to raise and fix the cab.
The loader is equipped with different engines depending on the model. If this is a CUMMINS A2300 motor, made in the USA, then it gets to the name of the model "K" and is called MKSM-800K. And when the German HATZ 3M41 engine is installed, then the MKSM-800N.
