Doosan DE08 Complete Diesel Engine Assembly | Aftermarket Excavator Engine Replacement Spare Parts Compatible With Doosan DE08 Series Heavy Construction Machinery

Welcome to HanRui hydraulic supply. We specialize in providing the complete Doosan DE08 excavator diesel engine assembly, precision-manufactured as a heavy-duty aftermarket replacement part compatible with Doosan DE08 large engineering excavator equipment. All internal cylinder blocks, crankshafts, fuel injection assemblies and oil sealing components are CNC precision machined and passed strict factory power & temperature testing, stable high-torque power output for open-pit mining and mass earthmoving construction, plug-and-play direct fit without modification, cost-effective overhaul core component for global heavy machinery repair workshops.

• Africa & Australia open-pit ore quarry excavation, long-distance heavy ore transportation loading operation
• Southeast Asia mountain road, bridge and hydropower station foundation digging project
• Europe & Middle East highway, high-speed rail and large bridge foundation deep excavation construction
• Super-large river dredging, reservoir reinforcement and flood control water conservancy engineering
• Coastal bulk port yard expansion, heavy mineral cargo stacking and handling work
• Urban large municipal infrastructure reconstruction, deep pipeline and basement backfilling construction

• Engine insufficient power, weak digging torque under full heavy mining load
• Black exhaust smoke, incomplete fuel combustion and sharp fuel consumption rise
• 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 heavy 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 heavy load
• Long-term high temperature accelerates 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 friction produce metal vibration noise
• Swing oil leakage: Front oil seal abrasion causes continuous hydraulic oil spillage
• Swing stuck rotation: Deformed piston blocks smooth rotary movement under full mining load
• Swing overheating: Long continuous swing operation triggers whole hydraulic system high temperature failure

• Inconsistent two-side motor displacement leads to excavator travel deviation
• Broken travel reducer gear results in unilateral no driving force
• Slow climbing and heavy-load stall on mountain 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 Doosan DE08 series heavy excavator hydraulic power system, no cutting or refitting required
• Precision CNC machined cylinder block & crankshaft, high wear resistance, greatly reduce engine internal failure rate
• 100% factory power, temperature and sealing pressure testing before delivery, reduce on-site overhaul breakdown rate greatly
• High temperature resistant fluorine rubber sealing parts, adapt tropical high-temperature continuous 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
• 12 months full factory official quality warranty for all Doosan DE08 engine assemblies

• Model Number: DE08
• OEM Reference Part No: 65.01101-7090
• Applicable Equipment: Doosan DE08 Series Large Heavy Excavator
• Product Form: Complete Aftermarket Full Diesel Engine Assembly
• Core Function: Provide main power output for excavator full hydraulic working system
• Warranty Period: 12 Months Factory Quality Warranty
