The Yamaha 1UA-11610-20-00 84/85 RZ350 Top End Standard Piston Rings, Pins, Bearings, and Clips is a comprehensive kit designed for the maintenance and repair of the top end of the Yamaha RZ350 engine. This kit includes all the necessary components to replace the worn-out or damaged parts in the engine's cylinder head and piston assembly.
The piston rings in this kit are designed to seal the combustion chamber and prevent oil and gas from leaking between the cylinder walls and the piston. The set includes two compression rings, two oil control rings, and two skirt rings. The compression rings help to contain the combustion pressure and ensure proper piston-to-cylinder wall contact, while the oil control rings prevent oil from entering the combustion chamber during the compression stroke. The skirt rings, on the other hand, help to reduce friction between the piston and the cylinder wall.
In addition to the piston rings, the kit also includes the necessary hardware to replace the bearings and pins in the top end of the engine. The kit includes four piston pin bushings, four connecting rod bushings, four crankshaft bearing bushings, and eight piston pin clips. The piston pin bushings are inserted into the piston pin to reduce friction and wear, while the connecting rod bushings and crankshaft bearing bushings are used to reduce wear on the connecting rod and crankshaft. The piston pin clips are used to secure the piston pin in place.
The kit also includes six bearing retainers and six bearing seals. The bearing retainers are used to secure the bearings in place, while the bearing seals help to prevent oil leaks around the bearings. This kit is suitable for Yamaha RZ350 engines with model numbers 84 and 85.
