Names of Honda lawn mower Engine parts
A lawn mower is a machine that clears weeds to keep the environment clean. It is found in households and industries to beautify the environs.
As a user, you need to be familiar with the lawn mower so that you can fix some minor fault that is affecting the machine’s functionality.
A lawn mower is a straightforward machine that can be repaid by those that are not even a professional. I want to share some information to help you identify Honda lawn mower parts.
1. Set of gasket: A gasket is a mechanical seal that fills the space between two or more mating surfaces to prevent leakage from or into the joined objects while under compression.
2. Lawnmower Blade: First, the blade pulls the grass up and cuts it. Then, clippings are sucked inside the deck and chopped into tinier pieces. Finally, the blade’s innermost curve produces air pressure to blow the small clippings out, where they are used to feed the soil.
3. V-Belt: The V-belt acts as a transmission belt. Connecting the V-belt pulleys, it transmits the force from the engine to the ancillary components, including the alternator and the hydraulic pump for the power steering.
4. Wheel: A wheel is a tire that helps the lawnmower to move to and fro. It is the wheel that makes mobility possible. Without the wheel, mobility in a lawnmower would not be possible.
5. Flexible Shaft: Flexible shaft is a round link between the main engine and the lawn mower propeller. Flexible shafts make the grass-turning handle easily deflected in any direction desired.
6. Filters: These include oil, fuel, and air filters. Oil filter, filter the oil to remove invisible particles from the engine oil. The fuel filter is responsible for eliminating dirty or any foreign particles from the fuel so that the carburetor can function well.
Air filter filters the air talking in by the engine. Since a lawnmower usually works in a dusty place, there is a need for the air to be clean before it goes into the engine.
7. Recoil Starter: is used to start the engine. The starting coil must rotate the engine with enough speed to help it start running itself.
It helps to rotate the engine before it can continue running on itself. After initial rotation, the engine moving parts can keep running.
8. Carburettor: A carburetor is a tool that aids in combining fuel and air in an internal combustion engine to assist internal combustion.
An internal combustion engine’s intake manifold receives the fuel and air mixture from this mechanism, which delivers the mixture to the cylinders.
9. Spark plug: Your spark plugs supply the spark that ignites the air/fuel mixture, creating the explosion that makes your engine produce power. These small but simple plugs create an arc of electricity across two leads that are not touching but close enough together that electricity can jump the gap between them.
10. Ignition coil: You depend on the ignition system to create a spark inside the combustion chamber, whether you pull the rope to start the engine or use a key on an electric start motor.
When you turn the flywheel on a lawnmower or small engine to start it, the magnets pass the coil (or armature).
This creates a spark. Coils are generally sealed water-tight components. As such, they are usually not repairable items. Routine checks on a coil are not necessary.
11. Throttle Cable: is used to regulate the engine’s speed. It can also be defined as a mechanism by which the power or speed of an engine is controlled. It is connected to the carburetor to reduce the intake of air or increase the intake of air.
12. Fuel tank: The fuel tank is a reservoir that holds the fuel supply and helps maintain its temperature below its flash point.
The fuel tank also serves as an important means of dissipating heat from the fuel that is returned from the engine.
13. Piston Rings: The piston rings transfer heat from the heated piston into the engine’s cooled cylinder wall or block. The piston ring and the cylinder wall both receive heat energy from the piston groove, which will eventually be transferred into the engine coolant.
14. Crankshaft: The crankshaft is responsible for the engine’s proper operation and converting a linear motion to a rotational movement. A shaft consisting of a series of cranks and crankpins to which the connecting rods of an engine
15. Connecting rod: The primary essential function of the connecting rod is to transmit the push and pull forces from the piston to the crankshaft. The connecting rod carries the power thrust from the piston to the crankpin
16. Engine Crankcase: A crankcase houses the crankshaft in a reciprocating internal combustion engine. In most modern engines, the crankcase is integrated into the engine block. It is like a human skeleton, and other components are like flesh.
17. Lawnmower: This is a lawn mower’s main ‘body’ where the blades are housed. Most lawn mowers will have a metal deck (steel or aluminum), but some are made of robust plastic.
18. Oil seal: Seals are used throughout the engine to keep oil where it’s supposed to be and protect the engine’s inner workings from dirt and debris, all of which are in plentiful supply on the road.
19. Flywheel: flywheel is a heavy wheel attached to a rotating shaft to smooth out the delivery of power from a motor to a machine. The inertia of the flywheel opposes and moderates fluctuations in the speed of the engine and stores the excess energy for intermittent use.
20. Piston: To receive the thrust from the explosion and transmit the force to the crankshaft through the connecting rod. It also acts as a seal so that the high combustion pressure does not escape the crankcase. In other words, it serves as a guide and a bearing for the connecting rod’s small end.
21. Clutch: A lawn mower clutch is a safety device that stops the blades from spinning while the lawn mower’s engine is still running. It also can be a matter of convenience for the operator. On older lawnmowers, a clutch stops the wheels from turning so the operator can empty the catcher without shutting off the engine.
What Types of Oil Good for Lawn Mower
A lawn mower engine can be a two-stroke engine or a four-stroke engine. Since two-stroke and four-stroke engines use different types of oil, you need to find out which kind of oil is suitable for your lawn mower.
Before attempting to change the lawnmower oil, it is vital to know the type of oil and the volume required.
Below we have answered this frequently asked question and explained the two most essential steps to understand your mower better regarding lawnmower oil type and volume.
You must consult your engine operator’s manual for information specific to your engine. Proper care and equipment maintenance are the keys to long engine life.
Before each engine starts, always check the oil dipstick for the appropriate oil level.
How to identify lawnmower engine oil type?
Air temperatures determine the correct oil viscosity for the engine. 5W30 synthetic engine oil is suitable for a lawn mower.
Vanguard 15W50 Synthetic Oil offers the best protection for equipment operating in hot temperatures.
Please note the following:
- Below 4°C, the use of SAE 30 leads to starting difficulties.
- Above 27ºCthe use of 10W30 can lead to higher oil consumption. Check the oil level more often.
The Association of Automotive Engineers has categorized engine oils that indicate viscosity (thickness) and the temperature at which engine oil can be used.
The SAE (Society of Automotive Engineers) is printed on every oil bottle and indicates whether the oil is synthetic or not.
Below is a table listing the SAE type and the temperature at which it performs best. The easiest way to find the best SAE for your lawnmower is to combine the information in your operator’s manual with the oil type descriptions below.
Recommended oils for small engines:
- Use SAE 30 in warmer temperatures of 5°C and above
- Use SAE 10W-30 for temperature ranges that fluctuate between -18°C to +38°C; this grade of oil improves starting in cold weather but may increase oil consumption at 27°C and above.
- The synthetic oil, SAE 5W-30, is best in cold temperatures from -30°C to +40°C and offers the best protection at all temperatures and improvement, starting with less oil consumption.
- Use SAE 5W-30 in freezing temperatures of 5°C and below.
- For continuous usages (temperatures between 20°F and 130°F), such as pressure washing contractors or landscape care, use Vanguard 15W-50 oil.
How to Repair Honda Lawn Mower
Maintenance and repairs of your lawn mower are essential for a trouble-free season. Rain, come sun, I always recommend the Honda lawn mower for users because of its reliability, durability, and simplicity of operation.
However, a Honda lawn mower can develop a fault requiring repairs after working long hours. In the few steps listed below, I will explain how to repair a Honda lawn mower.
- Before you start cleaning the device, first pull out the spark plug connector
- Then drain the supplies and disassemble the blade.
- Existing covers for the cutting height adjustment or a drive belt should also be unscrewed for a lawnmower repair.
- As grass residue has probably collected behind, it is best to remove coarse dirt with a scraper made of residual wood or plastic – metal would scratch the surfaces.
- Then wet the chassis with a spray cleaner and let it take effect. You can remove stubborn dirt with a cleaning rag or tear-resistant cleaning cloth.
The consequences of a lack of cleaning are visible on the mower when you see it permanently adhering; damp grass residue has already caused significant rusting on the chassis.
Here you could also positively influence the service life with a wire brush and some paint.
- If a foam filter is installed, it must be moist with oil after cleaning or replacement. Otherwise, fine dust could get into the engine – with the same consequences as omitted oil changes. On the other hand, paper and pleated filters must be installed dry.
- Before you reassemble the knife, you should check it. If the metal is bent or badly nicked, it must be replaced. You can re-sharpen a blunt blade with a double-post grinder or a file.
- Then check the cutter bar for imbalance and remove the burrs that have formed on the cutting edges with a sharpening stone – otherwise, the knife will quickly become blunt again.
- Sharpen lawn mower blades
