Complete rocker arm bridge incl. Shafts and valve adjuster for cylinder heads of Chinese 4-stroke engines 139QMB / QMA 50ccm. Changing the complete bridge makes much more sense than repairing them from parts. In most cases, significantly more components are damaged in a defect than at first sight. It also shortens the installation effort noticeably.
ATTENTION: It may happen that the length of the plunger is insufficient to reach the valves. In this case, the locknuts of the plunger are to be implemented under the lever. This is due to different cylinder heads and can occur with changing vehicles.
