The Multiquip 1685122320 Metal Crankpin M Standard Set is a genuine OEM component designed for the DLW300ES, DAC7000SSA, DAC7000SSW, and DAC7000SS series diesel light welders and ultra-silent diesel generators. Sourced directly through Multiquip's authorized parts channel, this standard-specification crankpin bearing set delivers the dimensional accuracy required to maintain proper crankshaft-to-connecting rod clearances. Correct fitment has been verified for the DLW300ES and DAC7000SS series, making this the straightforward choice for engine rebuilds and overhaul service on these machines.
Key Features
- OEM-Grade Bearing Material — Manufactured to the same metallurgical specification as the original, ensuring correct load capacity and surface hardness for crankpin journal contact.
- Standard Clearance Set — Supplied at standard (STD) specification for use with unworn or precision-reground crankpin journals during engine overhaul.
- Direct Engine Compatibility — Confirmed fitment for DLW300ES, DAC7000SSA, DAC7000SSW, and DAC7000SS — no shimming or machining workarounds needed for correct installation.
- Crankshaft Protection — Properly seated crankpin bearings maintain the oil film boundary that prevents metal-to-metal contact between the rod and crankpin, directly protecting crankshaft service life.
- Complete Set Supplied — Includes the full Metal Crankpin M Standard Set needed for the service interval, so you have everything on hand before teardown begins.
Crankpin bearings — also called rod bearings — sit between the connecting rod and the crankshaft's crankpin journal, allowing the rod to rotate smoothly as the crankshaft turns. They rely on a pressurized oil film to prevent direct metal contact; when that film breaks down due to wear, contamination, or oil starvation, the bearing surfaces score and the crankpin journal itself can be damaged. Replacing these bearings at the correct service interval — or during any engine overhaul — restores proper oil clearance, protects the crankshaft, and keeps the engine running within its designed power and efficiency range.
