The Multiquip 1733122970 Crankpin Metal is a genuine OEM component designed for Multiquip Welders and DCA-series diesel-powered generators including the DCA15SPX3 and DCA10SPX3. As a factory-sourced part, it meets the exact material and dimensional standards set by Multiquip for the original engine assembly. This bearing insert is a direct replacement for engines showing signs of crankpin wear, oil pressure loss, or connecting rod knock. Verify your model code against the fitment list — DAW-series welders, DCA15SPX3, and DCA10SPX3 — before ordering to ensure correct application.
Key Features
- OEM-Grade Bearing Material — Manufactured to the precise alloy composition and wall thickness required for the crankpin journal, ensuring correct oil film clearance and load capacity in the engine.
- Drop-In Engine Replacement — Engineered to seat directly into the connecting rod bearing saddle without reworking or shimming, following the original assembly procedure.
- Broad Fitment Across Multiquip Power Equipment — Compatible with DAW-series arc welders and DCA15SPX3 and DCA10SPX3 diesel-powered generator models.
- Protects Crankshaft Journal Integrity — A correctly fitted crankpin bearing maintains the oil wedge between the rod and crankshaft, preventing metal-to-metal contact that accelerates journal wear and leads to engine failure.
- Genuine OEM Sourcing — Supplied as a genuine Multiquip part, carrying the same part number 1733122970 used in factory service documentation for traceability and confidence in specification accuracy.
The crankpin metal — also known as a connecting rod bearing insert — sits between the connecting rod big-end bore and the crankshaft crankpin journal. Its job is to provide a precision-clearanced, lubricated surface that allows the rod to rotate smoothly around the crankpin as the piston reciprocates. A worn or damaged crankpin bearing reduces oil pressure, generates audible knocking from the lower end of the engine, and — if left unaddressed — can cause catastrophic crankshaft or connecting rod damage. Replacing this insert at the first sign of wear is one of the most cost-effective ways to restore engine health and extend service life in your Multiquip welder or generator.
