Description
Overview:
The Piston Ring (52 mm x 1.2 mm) for Makita engines is a compression ring that restores and maintains cylinder sealing in 2‑stroke machines. Manufactured from OEM‑grade, wear‑resistant material, it is designed for 52 mm bore cylinders and helps recover power, throttle response and starting reliability by ensuring correct combustion pressure. This is a non-genuine replacement for OEM No. 038-132-020, suitable for the Makita DCS7901 chainsaw and compatible platforms such as the DPC8112 cut‑off saw. Dimensions are 52 mm (approx. 2.05 in) diameter by 1.2 mm (approx. 0.047 in) thickness, matching the original specification for a precise fit and consistent performance.

Typical Applications:
Used during top‑end rebuilds or maintenance on Makita machines with a 52 mm bore, such as the DCS7901 chainsaw and related platforms. Ideal when addressing low compression, hard starting, loss of power or increased fuel consumption, ensuring the engine runs efficiently after cylinder or piston service.
