How To Lubricate A Gas Trimmer Gear

How To Lubricate A Gas Trimmer Gear

Buying any kind of equipment is a kind of lottery, but a lot also depends on the gardener. In caring hands, and Chinese samples serve for a long time and do not fail their masters at the wrong time. And if you forget on time grease gear lawn mowers, do not clean filters, use cheap low-quality gasoline, then garden equipment from the most famous brands will become a headache.

Gear Lubrication lawn mowers one of the most important elements of maintenance of a gas trimmer, which should be carried out directly by the user.

Time and procedure for the prevention of the gearbox.

I recommend that you necessarily carry out the prophylaxis of a new gas trimmer immediately after purchase, with the addition of lubricant to the gearbox. Despite the high cost of gardening equipment, some manufacturers save and put grease only at a minimum, at the time of break-in.

How often to lubricate the lawn mowing gear.

Often, a routine inspection of the transmission with the addition of liquid grease is carried out once a year at the beginning or end of the season. If the gas trimmer is not used by you in professional volumes, this is enough.

For large mowing volumes, it is necessary to lubricate the lawn mowing gearbox every 20-50 hours of operation. If the operating conditions of the garden equipment are difficult, for example, a large field is mowed at a time, and the lawn mower does not have time to cool down, or cheap lubricants are used, then the grease must be checked and added every 20 hours of operation.

Indirect evidence that it is necessary to lubricate the gearbox may be overheating or increased unit noise. In these cases, if during inspection it is found that there is enough lubricant in the assembly by volume, then I recommend that it be replaced as a whole, while it is advisable to choose a different manufacturer of auto chemical goods. Also, a complete replacement of the lubricant, with disassembly and washing of the unit, I recommend when buying a used gasoline trimmer.

Assortment of lubricants for gardening equipment

According to the instructions, a special transmission fluid grease should be used to lubricate the bevel gear. As a rule, gardening equipment manufacturers produce and recommend the chemistry of their brand as the most adapted to their devices.

At the same time, in order to reduce the cost of operating garden equipment and increase the attractiveness of the auto chemical brand, grease for garden equipment is usually produced multifunctional. It is intended not only for the lubrication of gearboxes of gasoline trimmers, but also for the processing of hoses, gears and gearboxes of any garden equipment and mechanical devices operating under high loads.

Even if the specialized lubricant for the gearbox was almost completely developed during operation, the additives still create an effective lubricating protective film on the surface of the gears.

It should be noted that many owners of lawn mowers in the former CIS expanses use conventional Litol-24 or lithium-based grease for lubricating the gearbox. It is convenient to refuel the gearbox with a 5-cc medical syringe. Many motorists, instead of the side screw, pick up the threads and screw the grease fitting from the cars that have served their crosspieces. This refinement allows the addition of Litol without disassembling the assembly using a grease gun.

An undoubted advantage of using Litol and lithium-based grease for refueling lawn mowing gears is the reduction in cost of operation. But there are nuances due to which spears break on forums of gardeners of Internet space. My thoughts on what can be lubricated with lithium-based lubricants and what is not, read the article “ Litol as a grease for lawn mowing gear “.

For safety reasons, in order to avoid accidental start-up, all preventive work on the lawn mower must be carried out with the electric cap / plug removed from the candle. Do not turn the trimmer over to avoid gas leaking.

We unscrew the side screw on the lawn mowing gear. Depending on the manufacturer of the garden tool, a turn-key bolt may be used instead of a hexagon screw, usually by 17. The thread is normal, turn off counterclockwise. Do not lose the sealing washer.

Add specialized grease

If no grease is visible on the inside of the screw, add 3-4 grams. Turn the gear by hand, changing the direction of rotation so that the grease is distributed over the gears. Repeat the operation several times. On average, about 5 to 10 g is included in the gearbox. The assembly must be completely filled with grease, taking into account the installation of the screw. Then reinstall the screw by tightening it firmly.

As you can see, it will not take a lot of time or special skills to lubricate the gearbox on the lawn mower. Usually, we’re going to take longer than we do the entire amount of preventive work. Reliable to you garden equipment. Share your experience with petrol trimmers in the comments.

  3. Prevention and possible malfunctions of the gearbox

A responsible approach to maintenance is the key to a long tool life. One of the requirements of the lawn mowing operation is timely lubrication of the gearbox, as well as filter cleaning. What composition to lubricate the gearbox, every user of such a unit knows. First cleaned in several stages, then remove the element from the casing. It is cleaned with gasoline, dried. A place for the filter is prepared carefully, cleaning it from dust and old oil. The main signal for lubricating the lawn mowing gear is extraneous noise and fast heating of the equipment. This suggests that it is necessary to lubricate the spare part as quickly as possible. The lubrication intervals are indicated in the lawn mowing instructions. Experts say that gearboxes need to be serviced every 15 hours.

Lower and upper gear lubrication

There are tips that recommend lubrication at the end of the season. However, most people find it best to do this at the beginning of each season. When we repair the unit, as well as carry out any disassembly, it is necessary to use lubricants. The gearbox must be additionally lubricated when the old trimmer is inserted.

Modern trimmers are equipped with a gearbox that measures the angle of transmission of mechanical energy between two components: a shaft and a head. Bevel gears are considered common, they easily withstand high speed, are equipped with smooth gearing, as well as an increased level of bearing capacity. The body includes a shaft, a gear wheel, which is pressed onto the driven shaft. In order to reduce friction, bearings are mounted on the shaft support points.

Grease for gas trimmer

Properly selected lawn care gives a guarantee of durability and high-quality equipment. Manufacturers try to take into account all the nuances and prescribe what materials to use for maintenance. Usually, the specific type of lubricant is not indicated, just well-known standards are given that lubricants must meet.

The lubricant must be selected in such a way as to take into account the temperature regime, rotation speed, load dynamics and vibration. The main requirement is that this mixture remains in the zone of maximum friction.

Based on the above information, it should be noted that lawn mowers manufacturers are developing universal additional tools for their equipment. It can be served by general industrial compounds. The main condition is compliance with the operating conditions, namely, the presence of a substance against rust and lime, as well as a filler, which consists of a solid lubricant. Grease is poured into the gearbox in a special hole, the assembly is not dismantled.

Replacement is quick enough.

  1. First, turn off the device from the network. Petrol devices must be drained from gasoline.
  2. If the lubricant changes completely, then be sure to flush the gearbox. To do this, first fill in the cleaner, then rinse the gearbox well, then drain. It is important to clean the case completely.
  3. The special tool that comes with the trimmer must unscrew the gearbox plug.
  4. We apply a new lubricant: we insert a syringe with a tube into the hole and squeeze out the lubricant (2-5 ml).
  5. Manually rotate the shaft, turn on the braid at low speed without load. This is necessary so that the lubricant is qualitatively distributed in places subject to maximum friction.

Prevention and possible malfunctions of the gearbox

Lawn mowing requires the first preventive maintenance immediately after the acquisition, because the manufacturer puts a small amount of grease. If the trimmer performs a small amount of work, then grease the device at the beginning and at the end of the season. If the lawn mower works a lot, then lubricate after 30-55 hours of operation.

The main malfunctions include the most common options.

  • Strong heat. This indicates that the grease has run out. It is necessary to add lubricants and run them in a weak mode.
  • The gearbox vibrates or staggers. This situation indicates mechanical damage.
  • There is a knock. Then the bearing collapsed, the boot is damaged.
  • If the trimmer knife is stuck, then the mechanism should be changed completely.
