The Multiquip 1685121982 Piston Pin Bush is a genuine OEM component designed for DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, and DAC7000SSA diesel-powered generators, as well as DLW300ES series welders. Sourced directly from Multiquip, this bush maintains the exacting tolerances required to keep piston pin movement stable and controlled under operating load. Confirm your model code before ordering to ensure a direct, correct-fit installation.
Key Features
- Precision-Bore OEM Tolerancing — Manufactured to Multiquip's exact bore dimensions, ensuring the piston pin seats and rotates with the correct clearance to prevent premature wear on connecting rod and piston.
- Drop-In Engine Replacement — Matches the original bush profile and press-fit diameter, allowing installation without machining or modification to the bore housing.
- Broad Generator and Welder Fitment — Confirmed for DA7000SSA2, DA7000SSA2GH, DAC7000SS, DAC7000SSW, DAC7000SSA, and DLW300ES series units from Multiquip's diesel generator and welder lineup.
- Protects Connecting Rod Integrity — A correctly fitted piston pin bush distributes load evenly across the small end of the connecting rod; a worn or oversized bush allows lateral pin movement that accelerates bore damage and increases engine noise.
- Genuine OEM Part — Carries Multiquip OEM part number 1685121982, so you can cross-reference against your parts manual with confidence and avoid fitment guesswork.
The piston pin bush — sometimes called a small-end bush — is a precision sleeve pressed into the small end of the connecting rod. It provides a hardened, low-friction bearing surface for the piston pin to pivot against as the piston moves up and down in the cylinder bore. When this bush wears, clearance between the pin and rod increases, producing a characteristic knock and allowing the pin to move laterally. Left unaddressed, this accelerates wear on the piston boss, connecting rod, and cylinder wall, and can ultimately lead to engine failure. Replacing the bush at the correct service interval restores proper pin retention and protects the surrounding engine components.
