This professional heavy-duty rebuild solution is engineered exclusively for Doosan DB58 / DB58T / DB58TI / DB58TIS inline 6-cylinder diesel engines — the reliable power core for 20-25 ton class excavators and mid-size construction machinery. Manufactured to Doosan/Daewoo's strict OEM standards and certified by ISO9001/TS16949, it integrates all critical components required for full engine overhaul.
12 Months (Under Normal Heavy-Duty Operating Conditions)
Core Features
ASME-Certified Metal Gaskets: Spiral-wound stainless steel construction meets ASME B16.20 standards, withstanding 600℃ high temperatures and 15MPa pressure — 2× longer service life than composite gaskets in heavy-load operations.
OEM-Matched Precision: All components tailored to DB58's 102×118mm bore-stroke and dry-type liner design, ensuring zero fitment issues and seamless installation with Doosan original engine parts.
Complete Overhaul Solution: Includes every critical part for full DB58 engine rebuild — no separate purchases needed, reducing procurement time by 40% and maintenance costs by 35%.
Heavy-Duty Durability: Forged pistons resist wear under 2200rpm continuous operation, while metal gaskets maintain sealing integrity against vibration and temperature fluctuations.
Performance Restoration: Fixes compression loss (restores 28kg/cm² standard), oil/coolant leakage, and power drop, returning DB58 engines to factory-level torque and fuel efficiency.
Rigorous Quality Testing: 100% pre-shipment inspection including gasket pressure sealing tests, piston dimensional verification, and bearing wear resistance checks.
