The Multiquip 1586123860 Metal Crankshaft 0.20MM Set is a genuine OEM undersized bearing set designed for DAC7000SS, DAC7000SSW, DAC7000SSA, and DLW300ES series equipment. Sourced directly from Multiquip, this is an exact OEM component engineered to the same tolerances as the original, ensuring correct journal clearance during engine rebuilds. If you are reconditioning a crankshaft that has been machined 0.20mm undersize, this is the correct bearing set to restore proper oil film thickness and crankshaft support. Confirm your unit's model code against the fitment list before ordering to ensure you receive the right specification.
Key Features
- OEM-Grade Bearing Tolerancing — Manufactured to the same dimensional specification as the original, maintaining the precise 0.20mm undersize clearance required for a reground crankshaft journal.
- Direct Engine Rebuild Fitment — Seats into the engine block and connecting rod in place of the standard bearing set, with no additional machining needed beyond the 0.20mm crankshaft grind already performed.
- Confirmed Fitment for DAC and DLW Series — Compatible with DAC7000SS, DAC7000SSW, DAC7000SSA ultra-silent diesel generators, and DLW300ES series diesel light welders.
- Restores Proper Oil Film and Crankshaft Support — Correctly sized bearings maintain the oil wedge that separates the crankshaft journal from the bearing surface, preventing metal-to-metal contact and premature engine wear.
- Genuine OEM Part — Supplied as an authorized Multiquip OEM component, so fitment, material grade, and dimensional accuracy match the original engine design.
Crankshaft bearing sets provide the precision bearing surface between the crankshaft journals and the engine block or connecting rods. During an engine rebuild, if the crankshaft journals show wear or scoring, they are machined to a standardized undersize — in this case 0.20mm below the original diameter — and a matching undersized bearing set is installed to restore correct operating clearance. Using the wrong bearing size results in either excessive clearance, which causes oil pressure loss and knocking, or insufficient clearance, which risks seizure. Installing the correct 0.20mm set, such as Multiquip 1586123860, is a critical step in completing a proper engine overhaul on affected DAC and DLW series units.
