Cylinder Sleeves

Masterparts supplies a variety of cylinder sleeves, compatible with a very wide range of automotive engine makes and models.

The sleeves are strong and durable, with excellent wear resistance.

What are cylinder sleeves?

Also known as cylinder liners, cylinder sleeves are long, round, elongated components manufactured from high-grade, heat-treated iron alloy.

They enclose the pistons and piston rings as they move up and down during the combustion process.

Why sleeve an engine?

The key role of cylinder sleeves is to protect the cylinders from excessive wear and corrosion. As such, they operate under extreme heat and pressure. They’re needed to support optimal engine performance.

In addition to providing a seamless lubricated sliding surface for the pistons and piston rings, cylinder sleeves disseminate heat to the coolant and help prevent combustion gases from escaping.

Cylinder sleeves are also useful in the following special cases:

  1. When an engine block is cracked or damaged, repairs often involve boring out a cylinder. Installing a sleeve can restore the original bore size. It can plug the “gap”.
  2. Some diesel engines are over-bored to increase engine displacement and create a more powerful engine. Sleeves protect the cylinders from the extreme pressure produced inside the bore of high-performance engines.

Types of cylinder sleeves

There are two main types of cylinder sleeves – dry cylinder sleeves and wet cylinder sleeves.

Dry sleeves have no direct exposure to the engine coolant. They’re held in position in the cylinder block by a flange. Dry sleeves have thinner walls than the wet liners.

Wet cylinder sleeves interact directly with the coolant. They’re sealed at the bottom to prevent coolant from leaking into the crankcase. They usually have a coolant gap between the engine block and the liner. As a result, the walls are thicker.

Due to their direct contact with the water jacket, wet cylinder liners have enhanced heat transfer and cooling properties.
