51.01201-0521 MAN CYLINDER LINER

The MAN 51012010521 cylinder liner is a critical component within the engine's cylinder block, providing a durable and precise surface for piston travel. These liners are used in heavy-duty diesel engines, ensuring efficient combustion and minimizing friction. Manufactured in Germany, these cylinder liners boast enhanced thermal conductivity and wear resistance, contributing to extended engine life and improved performance. The dimensions are 258 x 150 x 150 mm. These are basically the walls of each cylinder in your engine. They’re these tough, precisely – made sleeves that the pistons move up and down inside. They handle a lot of stress from combustion – that explosion that makes your engine run. They guide the piston’s motion, seal the combustion chamber, and help transfer heat away from the explosion. It’s a core part of what makes your engine work. Without good cylinder liners, you don’t have a functioning engine. Think of it like this: the cylinder liner is where all the power actually happens. It’s the main working surface for turning fuel into motion. Everything else in the engine relies on these doing their job smoothly. Well, if these get scored, worn, or cracked, you lose compression. That means less power, rough idling, increased oil consumption, and eventually, engine failure. They act like a shield protecting the engine block itself from all that heat and pressure. You’ll notice if one goes bad – usually through a loss of power, strange noises, or seeing a lot of smoke coming from the exhaust. If you need to replace one, you can sometimes find just the liner itself, but often it's a bigger job involving a complete engine overhaul. We carry a good selection of these at Fixparts Online if you’re looking, and we can help you find the right size for your vehicle. Year-round reliability: cylinder liner (MPN 51012010521) includes a 12-month warranty!
