VEGE Remanufactured DB01 3.8L 231ci Car Truck Long Block Engine

Description

Plastic coolant elbow fracturing and lower intake manifold gasket erosion vanish after fleet workshops mount the VEGE Remanufactured DB01 3.8L Long Block Engine. This 231ci 6-Cylinder commercial long block repower unit yields 200HP for commercial fleet transport vehicles. Technicians must check upper intake manifold heat stovepipe clearance to prevent hot EGR exhaust gases from deteriorating composite intake plenums.

Heavy-duty ASTM A48 Class 30 gray iron forms the deep-skirt crankcase, resisting severe thermal shock during daily commercial service. The VEGE engine core utilizes induction-hardened nodular iron camshaft lobes paired with stellite exhaust valve faces. Cranking starter draw pulls 12V 160A. Dry unrigged mass measures 390 lbs within a 25in length, 24in width, 26in height mounting stance holding 4.5 quarts oil.

Key Features of VEGE DB01

Commercial transport fleets buy VEGE DB01 commercial long block packages to upgrade reliability during demanding regional route schedules. Assembly cells maintain verified industrial engine rebuild clean-room assembly practices throughout production.

• Cast nodular iron crankshaft features micro-polished journals holding 0.0013in hydrodynamic oil film clearance.
• Counter-rotating balance shaft utilizes precision needle bearings to eradicate second-order engine vibration orders.
• Diamond-honed iron cylinder walls promote immediate piston ring seating during commercial startup.
• CNC milled deck surfaces eliminate gasket fire ring distortion across high combustion pressure phases.
• High-volume internal oil pump delivers 50 PSI pressure to upper valvetrain pushrod channels.
• DB01 commercial core casting incorporates cross-bolted center main bearing bulkheads to prevent crankcase flex.
• Hypereutectic aluminum pistons resist thermal ring-land pinch at elevated coolant temperatures.

Dynamometer Load Verification Bench Data

Dynamometer load trials verify 200 continuous BHP alongside 225 ft-lbs torque output at 4400 RPM continuous operational rating. Galley pressure maintains 50 PSI at 195°F oil sump temperature, while exhaust gas temp levels off at 1210°F during dyno load. Bench sensors record 180 PSI compression across all six cylinders within 3% balance. Crankshaft runout checks at 0.0003in TIR on the DB01 long block engine.

Field Service Guidelines Operating Boundaries

Mechanical throttle linkage requires 4 lbs pull effort on the throttle cam pivot assembly. This powertrain is NOT manufactured for rear-wheel drive longitudinal commercial trucks or industrial marine drive installations. Maintenance personnel must follow standard shop procedures during commissioning.

• Drain break-in engine oil reservoir and replace oil filter at 500 miles or 30 hours.
• Set hydraulic roller lifter preload depth between 0.035in and 0.045in before valve cover installation.
• Check lower intake manifold retention bolts after the initial two operating cycles.

Warranty Statement Shipping Pallet Inventory

Every commercial build complies with VEGE assembly standard metrics backed by a 3-Year 100,000-mile parts warranty. The timber freight crate houses the long block core, steel oil pan, aluminum timing cover, stamped valve covers, oil pickup tube, and signed dyno verification form.
