The Multiquip 0402001228 Dowel Pin SAA6D125E-5 DCA-300SSK4 is a genuine OEM component designed for the DCA-300SSK4 ultra-silent generator. As a direct OEM replacement, this dowel pin is manufactured to the exact dimensional tolerances required for precise component alignment within the Komatsu SAA6D125E-5 diesel engine that powers the DCA-300SSK4. Sourced directly through Multiquip's authorized parts network, 0402001228 ensures a correct, drop-in installation with no guesswork on fitment.
Key Features
- Exact OEM Dimensional Tolerance — Manufactured to the precise diameter and length specifications required for proper component alignment in the SAA6D125E-5 engine block.
- Direct OEM Replacement — Installs in the same position as the original, maintaining the correct positional relationship between mating engine components without additional fitting or machining.
- Confirmed Fitment for DCA-300SSK4 — Verified for use with the Multiquip DCA-300SSK4 ultra-silent generator equipped with the Komatsu SAA6D125E-5 diesel engine.
- Alignment Integrity Under Load — A correctly sized dowel pin keeps critical engine components locked in position during operation; an undersized or worn pin can allow micro-movement that accelerates wear on mating surfaces.
- Genuine Multiquip OEM Part — Backed by Multiquip's OEM supply chain, ensuring material grade and surface finish meet the original equipment specification for this engine family.
A dowel pin is a precision-ground cylindrical fastener used to accurately locate and align two mating components — such as an engine block and a mating housing — so they seat in exactly the correct position relative to one another. Unlike threaded fasteners, which provide clamping force, the dowel pin's job is purely positional: it prevents lateral shifting between parts during assembly and under the vibration and thermal cycling of engine operation. When a dowel pin is damaged, corroded, or missing, mating components can shift out of alignment, leading to uneven gasket loading, accelerated wear on bores and bearing surfaces, and potential engine damage over time.
