GT60 Replacement Cylinder Gasket OS28614000 for RC Engines by O.S. Engine  [OS28614000]

Durability and Care for GT60 Gasket

This O.S. Engine cylinder gasket is intended as a replacement component for GT60 model engines used in RC glow applications. It provides the seal between the cylinder head and crankcase to protect compression and stop leak paths that can degrade idle quality and tuning behavior.

Compatibility is governed by the GT60 designation, so confirm your engine variant prior to purchase. The gasket does not change engine settings, but maintaining a good seal helps ensure combustion pressure remains stable, which makes tuning adjustments more predictable over time.

Installation notes - remove old gasket remnants and clean mating faces, place the gasket flat on the cylinder base, and tighten head screws evenly in a cross sequence to prevent distortion. Avoid overtightening and confirm the gasket seats flat before final torqueing. Check again after the first runs for any seepage or compression loss as part of routine servicing.

Handling and service tips - replace the gasket any time the cylinder is removed for overhaul or when fuel or compression leakage is evident. Store spare gaskets flat to prevent creasing that could compromise sealing performance.
