The piston and piston rings are essential components of the petrol engine in your Scheppach or Woodster lawn mower. They compress the air-fuel mixture inside the cylinder, ensure efficient combustion and play a key role in the engine's performance. Over time, normal wear can reduce compression, making the engine harder to start, reducing power and increasing oil consumption.

In this category, you will find a wide selection of genuine pistons, piston rings, piston pins, circlips and related engine components compatible with many Scheppach and Woodster lawn mower models.

What is the function of a piston and piston rings?

The piston moves inside the cylinder to compress the air-fuel mixture before combustion. The piston rings provide a seal between the piston and the cylinder, helping to maintain compression while limiting the passage of combustion gases and engine oil.

A piston and piston ring assembly in good condition provides:

• Proper engine compression.

• Easier engine starting.

• Efficient combustion.

• Optimum engine performance.

• Reduced oil consumption.

• Longer engine service life.

Keeping these components in good condition is essential for reliable lawn mower operation.

Why replace a piston or piston rings?

During operation, pistons and piston rings are exposed to high temperatures, constant friction and significant mechanical loads. As they wear, engine performance gradually declines.

Common signs of wear include:

• Difficult starting.

• Loss of engine power.

• Low compression.

• Excessive oil consumption.

• Excessive exhaust smoke.

• Scored piston or worn or broken piston rings.

Replacing worn components restores engine performance and helps prevent more extensive engine damage.
