Makita 257377-6 Piston Ring

Product Description

The MAKITA 257377-6 is a replacement piston ring designed for use in Makita small-engine power equipment. The piston ring seals the combustion chamber, controlling compression and oil consumption to maintain engine performance over time. This is an OEM-specification part, meaning it matches the original manufacturer dimensions and material tolerances required for proper engine operation. Licensed small-engine technicians and experienced power equipment service professionals typically handle this type of internal engine repair.

The 257377-6 piston ring is intended for installation in the cylinder assembly of compatible Makita engine-driven equipment such as chainsaws, blowers, or similar small two-stroke or four-stroke units that use this piston ring specification. Always verify fitment against the specific model and engine assembly diagram before ordering, as piston ring dimensions are engine-specific and must match bore diameter and ring groove width precisely.

Installation Notes

Piston ring replacement is an internal engine repair performed by a qualified small-engine technician. Disable the spark plug and drain all fuel before disassembling the engine. Use the appropriate piston ring installation tool to avoid overstressing or cracking the ring during installation. Follow the manufacturer service manual for correct ring orientation, gap positioning, and torque procedures for the cylinder head fasteners.
