The Multiquip 14578ZJ1801 Pin C Decompressor is a genuine OEM component designed for CS8, CC8, and SP2 series flat and pavement saws. As a direct OEM replacement, 14578ZJ1801 is manufactured to the same specifications as the original, ensuring a correct fit within the engine's decompression system. This part is confirmed compatible across a wide range of Multiquip and Stow flat saw and pavement saw models, including SP2, SP213H20, SP2S20H20, CS813H20, CS8CE20H20, CC813H20, and related variants. Sourcing a genuine OEM part means you get the exact component the machine was built with, keeping the decompression system functioning as intended.
Key Features
- Genuine OEM Decompressor Specification — Manufactured to original engine tolerances, ensuring the decompressor pin engages and releases at the correct point in the engine cycle.
- Drop-In Engine Fit — Installs directly into the decompressor assembly with no reworking of surrounding components, maintaining the original engine geometry.
- Broad Saw Family Coverage — Fits CS8, CC8, and SP2 series models including SP213H20, SP2S20H20, CS8CE20H20, CC813H20, CS813H20, and additional flat saw and pavement saw variants.
- Consistent Cold-Start Performance — A correctly functioning decompressor pin reduces compression at startup, protecting the recoil or electric start system from excessive strain cycle after cycle.
- Long-Term Engine Protection — Worn or missing decompressor pins force operators to pull against full compression, accelerating wear on the starter assembly and increasing the risk of failed starts on the jobsite.
The decompressor pin works by briefly opening the exhaust valve during the compression stroke, temporarily reducing cylinder pressure to make the engine easier to crank over during startup. Once the engine fires and reaches operating speed, the pin retracts and the valve returns to normal operation. When this pin wears, breaks, or goes missing, the engine becomes significantly harder to start — placing strain on the pull starter or electric start motor and making reliable ignition difficult, particularly in cold conditions.
