Product description
A new cylinder is not always the solution when your cylinder has several thousand kilometers usage.Get your compression back up where it belongs by replacing piston rings or pistons instead of burdening yourself with major repairs. Our warehouse is full of original and tuning parts andreplacement parts like pistons, piston rings, cir clips, piston pins and gasket sets.
The main job ofpiston rings is to seal the combustion chamber against the piston housing and to channel the heat from piston to cylinder. Above this, pistons are also there to regulate the lubrication household, a major function. This means they are always working under pressure, often suffer wear and tear and should be replaced regularly. Loss of compression, lowered performance and poor start reaction are the exact description of worn out piston rings
.We offer piston rings up to4. oversize (os) for many models and cylinders. The listedbore always shows the size of the cylinder. There are normal and L-shapes, with tuning cylinders also trapeze and half-trapeze shaped piston rings.
take care when installing piston rings, do not over stretch, otherwise they may break. Pay attention to piston ring stop play, type and model. Trapeze rings have only one installation direction!The right equipment is a great help when working on cylinders: Piston ring pliers BU5045, BUZZETTI gudgeon pin tool installation/removal 15194000 and gudgeon pin chuck 17820000.OEM numbers (for comparisons):
