XYgdhqpt Piston Rings Set 78mm for Kawasaki FX/FR/FS V-Series — Two Complete Sets, Restores Compression

XYgdhqpt 13008-0569 13008-7005 78mm piston rings set is a direct-fit replacement kit designed to restore compression and reduce oil consumption for Ka-wasaki FX/FR/FS V‑series engines.

If your small engine is showing lower compression, excessive blow-by, or increased oil usage, worn or damaged piston rings are often the cause. This listing contains two complete sets of 78mm piston rings (part numbers 13008-0569 and 13008-7005) specifically compatible with Ka-wasaki FX651V, FX730V, FX691V, FR651V, FR691V, FR730V, FS651V and FS730V engines. Each ring set is produced to meet durability expectations and fit tolerances so you can return the engine to dependable service.

How will these piston rings affect engine compression and performance?

Replacing worn rings restores the seal between piston and cylinder, which improves compression and reduces combustion gas leakage. Better sealing typically leads to smoother idling, stronger throttle response, and lower oil consumption.

• Two full 78mm ring sets address multiple cylinders or future rebuilds.
• Precision sizing for correct piston-to-cylinder clearance.
• Improved combustion sealing reduces blow-by and smoke.

Will these rings fit my Ka-wasaki engine model?

These piston rings are specified for several Ka-wasaki V‑series engines; verify your engine model and piston diameter before purchasing. The kit lists compatibility with FX651V, FX730V, FX691V and FR651V, FR691V, FR730V, FS651V, FS730V, all using a 78mm piston diameter.

• Part numbers: 13008-0569 and 13008-7005 for cross-reference.
• Designed for 78mm pistons—measure piston diameter to confirm fit.
• Contact the seller for verification if you are uncertain about compatibility.

What materials and quality standards are used for these rings?

The rings are manufactured from high‑grade materials intended to withstand heat and wear typical in small four‑stroke engines. They are produced to meet or exceed common aftermarket quality checkpoints for durability and dimensional accuracy.

• Heat-resistant metal alloys for long service life.
• Machined edges and consistent ring gap tolerances to reduce failure risk.
• Packaged as two sets to support complete rebuilds or spare parts needs.

How should I prepare and install these piston rings?

Installation requires disassembly of the cylinder and piston; proper ring orientation and end‑gap setting are critical for a reliable install. If you are unfamiliar with engine rebuild procedures, consider a service manual or a professional engine technician to ensure correct installation and avoid damage.

• Clean piston grooves and inspect piston for wear before installing new rings.
• Stagger ring gaps according to the manual to prevent blow-by channels.
• Use correct ring compressors and torque settings during reassembly.

Who is this for? This piston ring kit is intended for mechanics, lawn‑care professionals, fleet maintainers, and DIY enthusiasts who service Ka-wasaki FX/FR/FS V-series engines and need a reliable, OEM‑compatible 78mm rings replacement. It’s suited for engine rebuilds, performance restoration, or preventative maintenance when compression loss or oil consumption indicates worn rings. Before ordering, confirm the part numbers and piston diameter to ensure a correct fit; if there’s any doubt, reach out for verification so you receive the right components for your engine project.
