Caterpillar Rotocoils: Precision Rotation for Valve Longevity

Prevent the formation of carbon in the valve guide as well as avoid the premature wear of the engine valves with our Rotocoils.

Caterpillar rotocoils are small but crucial valve train components designed to gently rotate your engine’s valves with every cycle, helping prevent uneven carbon buildup and extending valve life. By ensuring valves wear evenly and seals remain effective, rotocoils contribute to smoother engine operation, lower emissions, and reduced maintenance needs. Each rotocoil is engineered to fit specific CAT engine models including the 3304, 3306, 3406, 3408, 3412, and more so you get secure, reliable performance every time you replace one.

Available in a variety of part numbers, Caterpillar rotocoils are easy to match to your equipment for a perfect, maintenance-friendly fit. Regular inspection and replacement of worn rotocoils help avoid valve sticking, uneven wear, and potential engine performance issues keeping your equipment reliable for the long haul.
