VEGE Remanufactured DCT1 5.7L 350ci Premium Grade Long Block Engine

Description

Plastic front timing cover crank sensor air gap error and intake manifold corner coolant weeping vanish once fleet mechanics mount the VEGE Remanufactured DCT1 5.7L Long Block Engine. Supplying 255HP from a 350ci 8-Cylinder commercial long block repower format, this unit powers commercial utility fleet trucks. Installers must inspect reluctor wheel runout on the front crankshaft snout prior to installing replacement composite timing covers.

Cast from heavy ASTM A48 Class 30 gray iron, the engine block provides massive structural strength to counter torsional bending under load. The VEGE engine core utilizes induction-hardened nodular iron crankshaft journals and stellite exhaust valves. Cranking starter demand requires 12V 175A. Engine dry weight measures 460 lbs inside a 28in length, 26in width, 27in height chassis envelope holding 5.0 quarts oil.

Key Features of VEGE DCT1

Commercial transport fleets buy VEGE DCT1 commercial long block packages to upgrade fleet reliability during demanding delivery schedules. Assembly cells maintain verified industrial engine rebuild clean-room assembly practices throughout production.

• Nodular cast iron crankshaft features micro-polished journal surfaces with 0.0003in TIR runout tolerance.
• Heavy-duty hydraulic roller lifters eliminate needle bearing failure under high spring pressure loads.
• Centrifugally cast iron cylinder walls receive fine diamond plateau honing for long ring life.
• CNC milled deck surfaces ensure 0.0002in flatness to stop high-pressure cylinder head fire-ring blowby.
• High-volume internal oil pump maintains 50 PSI line pressure across demanding fleet hauling routes.
• DCT1 commercial core architecture incorporates reinforced main bearing web bulkheads for crankcase rigidity.
• Tri-metal copper-lead bearings establish 0.0015in running clearance to protect crank journals from wear.

Bench Dynamometer Load Calibration Data

Certified dyno testing confirms 255 continuous BHP and 330 ft-lbs torque output at 4000 RPM continuous test load. Pressure gauges register 52 PSI oil gallery pressure at 195°F oil sump temperature, while exhaust gas temp levels off at 1240°F during dyno load. Compression testing demonstrates 175 PSI per cylinder with under 4% variance across all eight cylinders. Crankshaft center runout measures 0.0003in TIR on the DCT1 long block engine.

Field Service Guidelines Operating Boundaries

Mechanical throttle lever operation takes 5 lbs pull force through the linkage bracket assembly. This powertrain is NOT manufactured for transverse vehicle platforms or vehicles equipped with mechanical flat-tappet conversion systems. Shop technicians must carry out standardized maintenance routines on all newly mounted units.

• Empty initial break-in lubricant reservoir at 500 miles or 30 run hours.
• Set hydraulic roller lifter preload depth between 0.035in and 0.045in before sealing valve covers.
• Verify cylinder head bolt clamping torque using factory angle-gauge procedures after initial run.

Warranty Statement Shipping Pallet Inventory
