Welcome to HanRui hydraulic supply. We specialize in providing the complete Doosan DB58 mini excavator diesel engine assembly, precision-manufactured as a heavy-duty aftermarket replacement part compatible with small engineering machinery equipment that adopts Doosan DB58 hydraulic power system. All internal cylinder blocks, crankshafts, fuel injection assemblies and sealing components are CNC precision machined and passed strict factory power & temperature testing, stable light-load power output for small mine, municipal and landscape construction, plug-and-play direct fit without modification, cost-effective overhaul spare part for global small machinery repair workshops.
- Small open-pit stone quarry excavation, short-distance ore loading operation
- Urban municipal road renovation, trench digging and underground pipeline laying project
- Residential garden, villa landscape and farm land reclamation construction
- Rural small river dredging, village reservoir flood control water conservancy engineering
- Indoor demolition, basement narrow space excavation and backfilling work
- Engine insufficient power, weak digging torque under light construction load
- Black exhaust smoke, incomplete fuel combustion and increased fuel consumption
- Engine oil leakage, cylinder gasket aging and crankcase oil seepage
- Continuous engine overheating, radiator blockage triggers high temperature alarm and power derate
- Difficult cold start, unstable idle speed and whole machine shaking under load
- Piston & valve plate wear leads to insufficient whole machine hydraulic pressure
- Pump overheating, metal knocking vibration and front shaft oil seal leakage
- Blocked oil suction filter creates cavitation, weak digging force under load
- Long working hours accelerate internal pump core aging damage
- Swing weak & slope sliding: Internal high-pressure oil leakage cannot hold machine steady on slopes
- Swing abnormal noise & jitter: Worn reducer bearing and gear metal friction vibration sound
- Swing oil leakage: Front oil seal abrasion causes continuous hydraulic oil spillage
- Swing stuck rotation: Deformed piston blocks smooth rotary movement under full load
- Swing overheating: Long continuous swing operation triggers whole hydraulic system high temperature failure
- Inconsistent two-side motor displacement leads to mini excavator travel deviation
- Broken travel reducer gear results in unilateral no driving force
- Slow climbing and stall on small mountain road slopes
- Long-term operation produces gear wear noise and persistent oil leakage
- Valve spool sticking causes unresponsive boom, arm and bucket digging action
- Internal valve leakage leads to automatic cylinder sinking when machine static
- Valve joint oil stain and frequent hydraulic oil consumption
- Overflow valve failure triggers system overpressure and hydraulic high temperature alarm
- 100% matched mounting dimension compatible with small excavator equipped with Doosan DB58 hydraulic power system, no cutting or refitting required
- Precision CNC machined cylinder block & crankshaft, tiny matching clearance, greatly reduce internal engine leakage
- 100% factory power, flow and sealing pressure testing before delivery, reduce on-site overhaul breakdown rate greatly
- High temperature resistant fluorine rubber sealing parts, adapt tropical high-temperature small construction sites
- Support single piece trial order and large batch wholesale for global machinery repair shops & spare parts distributors
- Export shockproof wooden case packaging to avoid collision damage during long-distance sea transportation
- 6 months full factory official quality warranty for all Doosan DB58 engine assemblies
- Model Number: DB58
- OEM Reference Part No: 65.01101-7080
- Applicable Equipment: Mini Excavator Equipped With Doosan DB58 Hydraulic Power System
