Cylinder studs Active, set of 4 pcs: a cylinder stud set for Active mopeds. The studs clamp the cylinder, head and crankcase together, ensuring a tight joint and a sealed combustion chamber.
Replace them if the thread is stretched or stripped, if they are corroded, and also during an engine repair if the studs have already been removed. Tighten the nuts evenly in a crisscross pattern. L - 200 mm, M6. Country: China.
