Lifan engine on a single-axle tractor which is better

Fuel system problems

The first step is to check the spark plugs. If they are dry, it may mean that gasoline is not getting to the engine. The main reasons will be: lack of fuel, the feed valve was closed, the hole in the tank plug is clogged, unnecessary objects get into the fuel system.

  • refuel a uniaxial tractor;
  • unscrew the fuel supply valve;
  • clean the gas tank cap;
  • remove all gasoline from the tank, after removing the fuel cock, and wash it with clean fuel. Then purge the jets in the carburetor using the fuel pump.

Motor problems

Engines running on different types of fuel (gasoline or diesel) have a different resource. For engines using diesel fuel, it is much larger, but it is gasoline units that are popular, due to the lower cost and ease of operation and repair.

Usually, of all faults, two main types can be distinguished:

  • startup problems;
  • problems with smooth operation.

Motor device

The engine device for the cascade walk-behind tractor is approximately the same when installing various modifications of motors. They include:

  • Cylinder-piston system with crank-crank mechanism.
  • Gas distribution mechanism.
  • Ignition, cooling, fuel supply system.
  • Muffler.
  • Manual start device.
  • Additional lubrication system.

When the candles are still wet

  • Carbon deposits on spark plugs. Clean them with a rough surface and wash.
  • The gap between the electrodes is increased or decreased. You need to adjust it to the required size.
  • The insulation of the wiring is damaged. It is usually replaced with a new one.
  • There was a short circuit of the mass on the STOP button.
  • The starter of the ignition system is faulty.

The rubber seals on the carburetor may also loosen, causing air to be sucked in. It is necessary to tighten the bolts, candles and inspect the gaskets between the cylinder and the candle head.

Another option for poor engine starting may be that the carburetor choke does not close completely.

The candles in the walk-behind tractor should not be wet

If the compression is broken, it will also be difficult to start the engine. The reasons are: carbon deposits on the valves, the inlet valve is deformed, or the piston rings are already worn out.

Malfunctions in the course of operation usually appear when the nodal connections of the engine, being exposed to overloads, fail, which leads to malfunctions.

Important! If you understand that the motor starts to make noise, work in jerks, you should immediately turn it off and cool it down, only then try to repair it.

When the engine began to pick up and decrease speed by itself, this is possible by loosening the traction and fastening the levers. To eliminate it, simply adjust the control drive.

If the engine loses power, it means that it is overheated. In this case, the motor can jam, which happens when the oil level in the crankcase is low, a nadir forms on the connecting rod head, or the oil sprinkler has become unusable.

Briggs

BriggsStratton Vanguard engines are used in a wide variety of applications. They are used in conjunction with a walk-behind tractor, a gasoline generator, a motor pump, a vibrating plate and so on.

This motor is suitable for AI-92 gasoline

This engine is a single-cylinder four-stroke carburetor type. It uses a cast iron liner, which significantly reduces the wear of the piston system. The crankshaft is located in a horizontal plane and has bearings, which increases efficiency. There is also an oil gauge and an air cleaning filter. The engine capacity is 205 cubic centimeters, and the power of the device reaches 6.5 hp, so it can be installed on medium and large vehicles.

The OHV mechanism makes it possible to reduce the size of the unit, efficiently fill the cylinder with a mixture of fuel and provide increased torque. High-quality electronic ignition determines a clear and reliable engine start. To make it easier to turn on the device, a decompressor was installed. Also, the enlarged muffler allows you to work almost silently. The device is quite small and weighs about 16 kilograms.

AI-92 gasoline is used as fuel, which is poured into a 3.6-liter tank. This ensures long and trouble-free operation. Despite the not too low cost, this device will pay for itself quite well, which is facilitated by the high quality.

Engine oil

When you have a uniaxial tractor as an assistant, you must constantly monitor the technical condition. Oil is a very important compound that needs to be changed on time. It is responsible in the unit for the lubrication, sealing, cooling and cleaning of the motor components.

When the device is in continuous operation, the oil remaining in the cylinder may burn out and oxidize, causing the uniaxial tractor to smoke. Substances with resins are also deposited in the parts, which leads to contamination. Therefore, it is recommended to use good foreign lubricants that already contain the necessary additives.

Which engine is better to put on a single-axle tractor Cascade

Internal combustion engines for a single-axle tractor Cascade are all: gasoline, carburetor, single-cylinder, four-stroke, air-cooled. The motor is started with a lanyard. Operating the device will not generate much noise and assumes acceptable vibration levels.

At the moment, engines for the Cascade walk-behind tractor are not produced in Russia. Therefore, you have to turn to foreign manufacturers for help. But the parameters do not always match the unit. Due to the difference in the seats and the diameter of the shaft, you also have to buy additional fasteners. So, which engine is better to put on a single-axle tractor Cascade??

Repair and adjustment, adjustment of revolutions

Any single-axle tractor will sooner or later be repaired, let it be Caiman, Patriot, Texas, Foreman, VIKING, Forza or some other. The procedure for its disassembly and troubleshooting is simple and does not require any special tools.

It should be noted that the manufacturer does not indicate specific wear limits for troubleshooting any engine components, therefore, the dimensions given below are indicated by analogy with other four-stroke air-cooled engines:

  • Drain the oil from the crankcase and the gearbox (if installed) by removing the drain plugs and the remaining fuel from the gas tank.
  • Remove the fuel tank, muffler and air filter.
  • Disconnect the carburetor attached to the cylinder head with two pins.
  • Remove the recoil starter mechanism and fan shroud.
  • Having fixed the flywheel with a handy tool so as not to damage the fan blades, unscrew the nut securing it.
  • After that, use a three-armed universal puller to press the flywheel off the landing cone.
  • If the reason for the disassembly was poor starting and reduced engine power, check if the keyway is broken, since in this case the flywheel will shift and the ignition timing determined by the magnetic mark on it will change.
  • Remove the ignition coil and lighting coil, if present on the engine.
  • Having unscrewed the valve cover mounting bolts, unscrew the four cylinder head mounting bolts located under this cover, and remove the head. To check the tightness of the valves, turn the head upside down with the combustion chamber and fill it with kerosene.
  • If kerosene does not appear in the inlet or outlet channel of the head within a minute, the tightness of the valves can be considered satisfactory, otherwise they must be rubbed with an abrasive paste to the seats or (if burnout is detected) replaced.
  • On models equipped with a gearbox, remove its cover and remove the output shaft, then press the drive gear or sprocket from the crankshaft (depending on the type of gearbox). Replace gears with noticeable tooth work.
  • Unscrew the bolts holding the rear cover around the perimeter and remove it, after which you can remove the camshaft from the crankcase.
  • Having thus freed up space in the crankcase, unscrew the bolts connecting the lower connecting rod cover to its body, remove the cover and the crankshaft.
  • Push the piston into the crankcase together with the connecting rod.

If you find any play in the bearings, replace them. Also, since the repair dimensions of the parts are not provided, they are replaced with new ones:

  • Connecting rod: with increased to a noticeable radial play on the crankshaft neck;
  • Crankshaft: in case of seizure on the connecting rod journal;
  • Crankcase: in case of significant (more than 0.1 mm) wear of the cylinder mirror in the greatest place;
  • Piston: in case of mechanical damage (chips, scuffing due to overheating);
  • Piston rings: with an increase in the gap in the joint over 0.2 mm, if the cylinder mirror itself does not have a depletion that reaches the rejection limit, as well as with a noticeable burnout of engine oil.

Before reassembling, lubricate all rubbing parts with clean engine oil, and clean the carbon-covered surfaces of the combustion chamber and piston crown in order to reduce the heat load in these places. The motor is assembled in the reverse order of assembly.

Tighten the cylinder head bolts evenly crosswise in two passes, the final torque should be 24 Nm. Flywheel nut pulls 70 Nm and connecting rod bolts 12 Nm.

After assembling the engine, as well as regularly during operation (every 300 operating hours), it is necessary to adjust the valve clearances. Order of operations:

  • Set the piston to the top dead center of the compression stroke (since there are no marks on the flywheel, check this with a thin object inserted into the spark plug hole). It is important not to confuse compression TDC with exhaust TDC. valves must be closed!
  • After loosening the lock nut, rotate the nut in the middle of the rocker arm to adjust the clearance for the corresponding valve, and then secure the lock nut. The gap, set with a flat dipstick, should be 0.15 mm at the inlet valve and 0.2 mm at the outlet.
  • Having turned the crankshaft exactly two turns, re-check the clearances. their deviation from the established ones may mean a large play of the camshaft in the bearings.
