Verified fitment includes SP2, SP213H20, SP213H20A, SP2S20H20, SP2S20H20A, SP2SCE13H20, SP2SCE20H20, SP2S13H20, CS813H20, CS820H20, CS8CE13H20, CS8CE20H20, CC813H20, CC8CE13H20, CC8CE20H20, CUTTER3, N35244, GA-9.7, and SGW-250SS. Sourcing 90012415000 directly through an authorized Multiquip dealer like DHS Equipment ensures you receive the correct part for the job the first time.

Key Features

• Genuine OEM Specification: — Manufactured to the exact thread pitch, head profile, and material grade required for precise valve clearance adjustment on compatible engines.
• Drop-In Replacement: — Threaded to match the original rocker arm assembly, allowing straightforward installation without reworking the cylinder head components.
• Broad Fitment Coverage: — Compatible with SP2 flat saw series, CS8 and CC8 Stow pavement saw series, GA-9.7 portable generators, and SGW-250SS welders, among others.
• Engine Performance Integrity: — Correct tappet adjustment maintains proper valve timing and combustion efficiency; a worn or out-of-spec screw leads to irregular engine idle, power loss, and accelerated valve wear.
• Authorized Multiquip Part: — Sourced directly through the Multiquip OEM supply chain, so part number this part matches current engineering documentation for covered models.

The tappet adjustment screw — also called a valve clearance screw — sits within the rocker arm assembly and allows a technician to set the precise gap between the rocker arm and the valve stem. This clearance is critical: too tight and the valve cannot fully close, causing compression loss and overheating; too loose and the engine produces excessive noise and uneven power delivery. When this screw stretches, strips, or loses its locking ability, valve clearance drifts out of specification and engine performance deteriorates quickly. Replacing it with the correct OEM part restores the adjustment system to its intended function and ensures the clearance setting holds reliably through normal operating cycles.
