Description
The 5.5-ton Doosan DH55 (and Daewoo Solar 055) is one of the most widely deployed utility excavators in the world. When field overhauls fail to restore compression, downtime on site halts operations immediately. Tatan Machinery stocks and supplies professionally remanufactured Yanmar 4TNV94L complete diesel engine assemblies (OEM reference: 2201-9008 / 22019008). Rebuilt strictly to factory micrometer tolerances with 100% brand-new internal wear parts, each unit delivers turnkey, drop-in performance backed by our 12-Month Comprehensive Replacement Warranty.

Remanufacturing Standard: What Components Are Brand New?
This engine is NOT a salvage yard pull with unknown hours. We completely strip the core to raw iron, crack-test all castings, and install 100% brand-new internal wear parts:
- 100% Brand-New Wear Components: Brand-new 94mm pistons, multi-piece piston ring packs, new cylinder liner sleeves, connecting rod bushings, crankshaft main bearings, rod bearings, and thrust washers.
- Core Inspection & Precision Honing: Engine cylinder block and cylinder head chemically decarbonized, ultrasonic cleaned, pressure-tested for thermal distortion, and precision deck-milled.
- Full Engine Gasket Overhaul: 100% brand-new multi-layer steel head gasket, crankshaft front/rear oil seals, and manifold gaskets to prevent field oil weeping.
- Mechanical Fuel Pump Calibration: The direct-injection pump is flow-tested on a diesel bench; injection nozzles are pop-tested for crisp atomization.
