VEGE Remanufactured DCH9 3.1L 189ci Compact Car Long Block Engine

Description

Lower intake manifold corner oil weeping and mismatched pushrod installations terminate upon sourcing the VEGE Remanufactured DCH9 3.1L Long Block Engine. Supplying 155HP from a 189ci 6-Cylinder commercial long block repower architecture, this package restores urban courier fleets. Technicians must verify distinct intake and exhaust pushrod lengths prior to torquing down individual rocker arm pivot studs.

Constructed around a 60-degree ASTM A48 Class 30 gray iron block with aluminum heads, this engine resists warping under load. The VEGE engine core incorporates induction-hardened nodular iron camshaft lobes paired with stellite valves. Starter electrical draw requires 12V 145A. Dry unrigged mass measures 330 lbs across a 22in length, 22in width, 24in height stance with 4.0 quarts capacity.

Key Features of VEGE DCH9

Regional transport fleets buy VEGE DCH9 commercial long block units to stop recurring intake sealing breakdown. Assembly cells maintain verified industrial engine rebuild clean-room assembly practices throughout production.

• Forged micro-alloy steel crankshaft features micro-polished bearing surfaces with 0.0003in TIR runout tolerance.
• Multi-layer steel cylinder head gaskets maintain combustion chamber seal integrity under severe thermal cycling.
• Diamond plateau-honed cylinder liners establish immediate compression ring seal during break-in running.
• Tri-metal copper-lead bearings maintain 0.0014in hydrodynamic running clearance to stop crank journal scoring.
• Precision-ground pushrod guide channels eliminate lateral valvetrain bind across high operational engine hours.
• DCH9 commercial core layout uses structural webbing along the engine valley to arrest chassis vibration.
• High-capacity internal oil pump sustains 48 PSI line pressure across demanding fleet highway duty.

Dyno Bench Output Thermal Boundaries

Automated test cells indicate 155 continuous BHP and 180 ft-lbs torque output at 4800 RPM continuous sweep testing. Instrumentation logs 48 PSI oil gallery pressure at 190°F oil sump temperature, while exhaust gas temp records 1200°F under dyno pull. Gauge checks verify 180 PSI compression across all six cylinders within 4% variance. Center journal deflection clocks at 0.0003in TIR on the DCH9 long block engine.

Chassis Installation Limits Maintenance Rules

Mechanical throttle lever operation takes 4 lbs pull force through the linkage bracket assembly. This engine is NOT engineered for longitudinal rear-wheel drive trucks or heavy industrial stationary equipment. Shop mechanics must observe verified commercial engine service procedures without exception.

• Flush break-in engine oil and swap spin-on filter at 500 miles service interval.
• Check hydraulic roller lifter pre-load depth between 0.030in and 0.040in before valve cover installation.
• Inspect cooling water crossover pipe O-ring compression seal after initial operating heat cycle.
