The Multiquip 1731122310 Crankpin Metal is a genuine OEM engine bearing component designed for the DAW-500S welder and DCA15SPX3 and DCA10SPX3 diesel-powered generators. As a direct OEM replacement, this part is manufactured to the exact tolerancing and material specifications required for proper crankshaft-to-connecting-rod clearance in these engines. Sourced directly through authorized Multiquip supply channels, the part ensures correct oil film retention and load distribution across the crankpin journal. If you're rebuilding or overhauling the engine in your DAW-500S or DCA-series generator, this is the correct crankpin metal to restore it to proper operating specification.
Key Features
- OEM-Grade Bearing Material — Manufactured to precise thickness and hardness tolerances required for correct crankpin-to-rod clearance and oil film maintenance in these diesel engines.
- Drop-In Engine Rebuild Fit — Machined to match the original journal dimensions, seating directly into the connecting rod bearing shell position without additional machining.
- Confirmed Fitment — Verified for the DAW-500S arc welder and DCA15SPX3 and DCA10SPX3 diesel-powered generator models.
- Protects Crankshaft Integrity — Correct bearing metal prevents metal-to-metal contact at the crankpin, preserving crankshaft and rod life during high-load operation.
- Engine Overhaul Accuracy — Using the correct OEM crankpin metal during a rebuild ensures proper oil clearance specs are met, which directly affects engine compression and longevity.
The crankpin metal is a precision bearing shell that sits between the connecting rod and the crankpin journal on the crankshaft. Its job is to maintain a controlled oil clearance that allows a pressurized film of engine oil to separate the rotating crankpin from the stationary rod surface, preventing direct metal contact under load. When crankpin bearings wear beyond their service limit, that oil film breaks down — leading to knocking, accelerated crankshaft wear, and eventually engine failure. Replacing the crankpin metal with the correct OEM part during a rebuild restores proper clearance and protects the engine's bottom end for continued reliable service.
