D13F Complete Diesel Engine Assembly | Aftermarket Heavy Excavator Engine Replacement Spare Parts Compatible With Vol.vo EC380D EC480D Series Construction Machinery

Welcome to HanRui hydraulic supply. We specialize in providing the complete D13F heavy excavator diesel engine assembly, precision-manufactured as a heavy-duty aftermarket replacement part compatible with Vol.vo EC380D EC480D large engineering excavator equipment. All internal cylinder blocks, crankshafts, fuel injection assemblies and sealing components are CNC precision machined and passed strict factory power & temperature testing, stable high-torque power output for open-pit mine, mass earthmoving and heavy load construction work, plug-and-play direct installation without modification, cost-effective overhaul core component for global heavy machinery repair workshops.

• Large open-pit iron ore, stone mine excavation, long-distance heavy ore transportation loading operation
• Highway, high-speed rail and large bridge foundation deep excavation construction
• Urban super-large municipal infrastructure reconstruction, deep pipeline and basement backfilling project
• Super-large river dredging, reservoir reinforcement and flood control water conservancy engineering
• Coastal port yard expansion, heavy bulk mineral cargo stacking and handling work
• Mountain area large farm land reclamation, quarry heavy digging and crushing 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 working pressure
• Hydraulic pump overheating, metal knocking vibration and front shaft oil seal persistent leakage
• Blocked oil suction filter creates cavitation, further weakens digging force under heavy load
• Long continuous high temperature operation accelerates internal pump core aging damage

• Swing weak & slope sliding: Internal high-pressure oil leakage cannot hold machine steady on inclined ground
• Swing abnormal noise & jitter: Worn reducer bearing and gear metal friction vibration sound
• Swing oil leakage: Front oil seal abrasion causes continuous hydraulic oil loss and frequent oil refilling
• 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 and walking skew
• Broken travel reducer gear results in unilateral no driving force and single-side stall
• Slow climbing and heavy-load stall on mountain steep 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 imbalance triggers hydraulic system overpressure and high temperature alarm

• 100% consistent mounting dimension compatible with Vol.vo EC380D EC480D excavator D13F engine 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 D13F engine assemblies

• Model Number: D13F
• OEM Reference Part No: 16017634
• Applicable Equipment: Vol.vo EC380D / EC480D 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
