Hedge Trimmer Engine

Piston Kit
Genuine Husqvarna part
By: Husqvarna
Part Number: 530071833

Here is a replacement piston kit for use with handheld lawn and garden equipment engines. The pistons in an engine are essential to transfer combustion power to the various working parts of the machine. Pistons might need to be replaced if they have suffered any sort of damage or corrosion. There are several parts to the system including the piston, rings, wristpin, and circlips. The damage or wear and tear could occur in any of these different parts. When replacing a piston, it is a good idea to replace all of the parts of the kit, not just the part that is having issues. This authentic OEM piston kit is compatible with string trimmers, leaf blowers, hedge trimmers, pole pruners, and edgers. It is sold individually and is compatible with Husqvarna, Craftsman, Poulan, Poulan Pro, and Weed Eater brands. Owners buying a piston kit need to be sure they are getting the right part for their make and model.

Piston Ring
Genuine Husqvarna part
By: Husqvarna
Part Number: 545154001

A piston ring is a component located between a piston and a cylinder and helps the engine operate correctly. This component maintains gas compression between the cylinder wall and piston, makes lubricating oil to prevent scuffing, transfers heat from the crown of the piston to the cylinder, and prevents the piston from hitting the cylinder wall. There are several signs that a piston ring needs to be replaced. Excessive smoke may come out of the engine, oil may be used more rapidly, and your equipment might have a decreased performance without the power it used to have. If the engine is still in good shape, but the rings have lost their tension, replacing the piston ring is the best solution. Inspecting the cylinder for wear is also important since damaged piston rings can lead to cylinder wear. This piston ring is a genuine OEM product directly from the manufacturer. It comes as an individual part. It can be used on hedge trimmer, leaf blowers, and trimmers from Husqvarna, Weed Eater, and Poulan. Several tools, including a screwdriver and wrenches, might be required to install the replacement part.

Flywheel Assembly
Genuine Husqvarna part
By: Husqvarna
Part Number: 545221701

The flywheel is a heavy metal wheel that connects to the rotating shaft. Its purpose is to help regulate how power is delivered from the motor to the rest of the tool. Its weight and inertia oppose and moderate small changes in the speed of the engine and holds onto that energy for use when needed. The most common problem with flywheels is for them to crack. As the engine begins to age and other parts begin to break down, excess vibration in the engine can cause the flywheel to wear down, grate, and even shatter. The flywheel needs replacing when the motor begins slipping into the wrong gear. The exact steps for replacing the flywheel will depend on the specific model being repaired. It should only require a screwdriver. This is a genuine OEM replacement flywheel assembly for gardening hand tools like leaf blowers, edgers, weed eaters, and hedge trimmers made by Craftsman, Husqvarna, Weed Eater, Poulan, Poulan Pro, Paramount, Turf King. This part ships individually.

Piston Kit
Genuine Husqvarna part
By: Husqvarna
Part Number: 530071785

This replacement piston kit is designed to be used with many different types of handheld lawn and garden equipment. The pistons are important parts of the engine. The crankshaft powers the pistons, so they move up and down within the cylinder. The purpose of the pistons is to transfer the gas that expands within the cylinder. The pistons can begin to wear out over time, which means that they could fail, which will cause serious problems for engine performance. If there are issues with the piston, a replacement piston kit is essential to get the machine back up and running. When a piston goes bad, it will cause the engine power to decrease. In some cases, the engine might lose all power. Replacement will require pliers, a set of wrenches, and a screwdriver to complete. This high-quality piston kit replacement is a genuine OEM part. It is sold individually. The part can be used for pole pruners, edgers, leaf blowers, string trimmers, and hedge trimmers.

Chainsaw Piston Ring
Genuine Husqvarna part
By: Husqvarna
Part Number: 545160401

Combustion engines operate because of the chambers that seal in the tiny explosions caused by fuel, air and a spark. The pistons are part of the process of taking power from those explosions, and the piston rings seal the combustion chamber so that all of the gases created remain inside of the engine's crankcase. This replacement piston ring will ensure that a chainsaw's engine can do that, as well as maintaining the right amount of oil between the piston and the cylinder wall. An OEM replacement part, this piston ring works with Craftsman and Husqvarna chainsaws, among others. It will require a wrench set, screwdriver and a pair of pliers to make the replacement. Sold individually.
