Kit includes: piston, rod, cylinder and o-ring. Note: Bearing screw must be torqued to 40-50 in. lbs. No compression usually means a worn piston and cylinder. (Make sure your valves are not broken by inspecting the valve plate as well.) A 30 minute repair well worth the time and money. We machine the rod for better fit. Part has 048-0088 marked on the rod.PLEASE NOTE: When installing, Slide piston down into cylinder. Failure to do so will damage piston ring.
Restore compression with this piston assembly kit. Low compression is usually caused by a damaged compression ring and/or a worn cylinder sleeve. If you can see light in between the outer edge of the compression ring and the cylinder sleeve, replace the components, or if the compression ring is torn, folded or damaged along the outer edge.
