The power, efficiency and duration of operation directly depend on the quality level of components for household equipment. Some units are distinguished by their low fuel consumption and small size, while others are distinguished by impressive power.

Some devices are characterized by a combination of advanced parameters, such are Honda parts . These components have established themselves as professional devices, and therefore they can often be seen on various walk-behind tractors.

Thus, Russian-made motoblocks, when retrofitted with Honda engines, demonstrate much higher performance indicators.

Most popular gasoline engines

Honda engine classification is represented by such series as GC, GX, GP, IGX.

The main features of Honda engines are air cooling and manual start, the weight of the extremely productive units is 25 kilograms, the balanced fuel consumption is 2.5 liters.

The most popular among other engines manufactured by Honda are the GX class engines . This series of engines undergoes regular revision, in connection with which their efficiency in terms of fuel consumption increases, as well as their environmental friendliness.

GX Series Engines are high-quality components for universal use and are designed for long-term and uninterrupted operation in extremely difficult conditions. With regard to power, in most cases it does not exceed 15 horsepower.

In the spring of 2010, Honda launched line GX-240, GX-270, GX-340, GX-390 … These units comply with strict EPA 3 Phase emission standards.

Noteworthy are the improved models GX130, GX-160, GX-200.

The following improvements have been introduced: variable ignition timing, higher compression ratio, improved carburetor performance, and a lighter piston. They contribute to increased power and torque, improved fuel efficiency, and reduced vibration and noise. In contrast to the characteristics, the dimensions and external outlines have remained practically unchanged . This has led to the fact that the engines of this series are easily replaceable, this process does not cause any particular difficulties. It is also worth noting the CG springs introduced into this series and distinguished by their special reliability.

Maintenance tips for motoblocks with a Honda engine

One of the main manipulations in the case of maintenance of motoblocks is to adjust the valves. The reliability of the engine and the entire walk-behind tractor directly depends on this manipulation. In particular, it is necessary to carry out this procedure if the walk-behind tractor is jerky, makes noise and gives out periodic malfunctions.

Setting the valves is the setting of the required clearance parameters. The norms for setting the gaps are often spelled out in the technical documentation of the device. All models have their own acceptable values in terms of clearances.

Acceptable valve clearances for a conventional device are as follows:

• in the case of the inlet valve - 0, 10 - 0, 15 mm;
• for the weekend - 0, 15 - 0, 20.

To adjust and dismantle them, you will need tools such as:

• set of wrenches;
• flat screwdriver;
• probes for 0, 10/0, 15/0, 20 mm.

For an optimal valve setting, the following manipulations should be performed:

• make sure the engine is not hot;
• detach the oil bath reservoir from the air filter and the filter element;
• loosen and disconnect with a wrench 4 bolts located in a circle on the protective casing;
• disconnect the starter and flywheel guard;
• at the end of the flywheel it is necessary to bring it to a stable position of the "dead center", the mark located on the edge of the cylinder blowing must coincide with the zero mark of the flywheel;
• detach the cover with a paronite gasket by unscrewing the 3 fixing bolts in advance;

• check the width of the gaps: the inlet valve is located next to the filter, and the outlet valve is located next to the muffler;
• to measure the interval, it is necessary to insert a dipstick between the valve and the rocker arm;
• if the distance does not correspond to the permissible, then adjust the elements using a spanner wrench and a screwdriver;
• clean all connectors of the device with a piece of cloth;
• collect the engine back;
• make sure the walk-behind tractor is working.

If there is a leak of engine oil from the gearbox of the walk-behind tractor, this indicates that it is necessary to replace the oil seal.

This can be done as follows:

• disconnect the cutters from the shaft, clean them from traces of dirt and oil;
• loosen and disconnect the bolts that fix the cover that protects the gearbox, if things are so that the cover adheres very well to the housing, knock on it with a hammer;
• remove the unusable oil seal, clean the place under it;
• squeeze out the sealant on the edge of the new gland, place the part in place, tighten the cover tightly.
