Tanaka 6686131 Piston Ring

Product Description

The TANAKA 6686131 is a piston ring designed as a direct OEM replacement component for Tanaka small-engine power tools. The piston ring seats in the groove of the piston and creates the compression seal between the piston and cylinder wall, maintaining combustion efficiency and preventing oil blow-by. This is an internal engine component installed during engine rebuilds or top-end service. Small-engine mechanics and power equipment technicians are the primary installers for this type of repair.

This piston ring is intended for use in Tanaka power tool engines requiring top-end service. Typical applications include situations where compression loss, excessive oil consumption, or visible ring wear indicate the need for piston ring replacement. It is suited for small two-stroke or four-stroke engine platforms found in Tanaka-branded outdoor power equipment.

Installation Notes

Installation should be performed by a qualified small-engine mechanic. Disable the ignition and disconnect the spark plug before beginning any top-end engine disassembly. Take care not to overstress or twist the piston ring during installation, as small-diameter rings are susceptible to cracking. Refer to the applicable Tanaka engine service manual for proper ring gap orientation and piston assembly procedure.
