The Multiquip 14579ZJ1801 Pin D Decomper (8.15) is a genuine OEM decompression pin designed for SP2, SP213H20, SP2S13H20, SP2S20H20, CS813H20, CS820H20, CC813H20, and related flat saw and pavement saw models. As a direct OEM part, 14579ZJ1801 is manufactured to the same specification as the original, ensuring correct fit and function across the full range of compatible machines. This pin is a small but critical engine component — choosing the correct OEM specification part is essential for consistent engine starting performance on these saws.
Key Features
- Genuine OEM Decompression Pin — Manufactured to original specification, ensuring the correct diameter (8.15 mm) and material hardness for consistent decompressor engagement in the engine cylinder head.
- Direct Drop-In Replacement — Engineered to seat and retain exactly as the original, with no reworking of the cylinder head or decompressor assembly required during installation.
- Broad Saw Compatibility — Fits a wide range of Multiquip and Stow flat saws and pavement saws including SP2, SP213H20, SP2S20H20, CS813H20, CS820H20, CC813H20, CC8CE13H20, CS8CE13H20, and additional SP2 series variants.
- Restores Easy Pull-Start Performance — A worn or missing decompression pin makes the engine difficult or impossible to start by hand; replacing it with this part restores normal cranking effort and reliable cold starts.
- Built for High-Cycle Saw Applications — Flat saws and pavement saws run hard in demanding cut environments; this pin is produced from materials rated to withstand the thermal and mechanical cycling of continuous engine operation.
The decompression pin works within the engine's automatic decompressor mechanism to momentarily release cylinder pressure during the starting stroke, reducing the force required to pull the recoil starter. This makes it possible to turn the engine over quickly enough to achieve ignition without excessive effort from the operator. When the pin wears, breaks, or falls out of position, the engine becomes extremely hard to start — and in some cases will not start at all — making prompt replacement essential to keeping the saw in service.
