VEGE Remanufactured 851A 2.5L 2438cc Premium Grade Long Block Engine

Description

Balance shaft drive chain chatter and oil pump front crankshaft seal grooving cease after installing the VEGE Remanufactured 851A 2.5L Long Block Engine. Generating 165HP from a 2438cc 4-Cylinder commercial long block repower format, this unit powers commercial route delivery vehicles. Mechanics must check balance shaft drive gear backlash marks during front timing cover assembly to eliminate gear whine.

Dense ASTM A48 Class 30 gray iron forms the engine block, providing lasting structural resistance against thermal bending under route service. The VEGE engine core pairs hypereutectic pistons with hardened steel camshaft profiles. Cranking demands 12V 145A starter power. Engine dry weight stands at 280 lbs within a 22in length, 21in width, 24in height chassis envelope with 4.8 quarts oil capacity.

Key Features of VEGE 851A

Commercial transport fleets buy VEGE 851A 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.

• Cast nodular iron crankshaft features micro-polished journal surfaces with 0.0002in TIR runout tolerance.
• Heavy-duty multi-layer steel cylinder head gaskets prevent inter-cylinder fire ring compression loss.
• 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 48 PSI line pressure across demanding fleet highway duty.
• 851A commercial core architecture incorporates reinforced main bearing web bulkheads for crankcase rigidity.
• Tri-metal copper-lead bearings establish 0.0013in running clearance to protect crank journals from wear.

Dyno Bench Output Thermal Boundaries

Certified dyno testing confirms 165 continuous BHP and 175 ft-lbs torque output at 4400 RPM continuous test load. Pressure gauges register 48 PSI oil gallery pressure at 195°F oil sump temperature, while exhaust gas temp levels off at 1220°F during dyno load. Compression testing demonstrates 180 PSI per cylinder with under 3% variance across all four cylinders. Crankshaft center runout measures 0.0002in TIR on the 851A long block engine.

Installation Requirements Negative Filter Rules

Throttle linkage pull effort registers 4 lbs on the mechanical pivot return spring assembly. This motor is NOT engineered for marine inboard installations or industrial pump drive units lacking radiator fans. Installation technicians must execute verified startup maintenance protocols without exception.

• Change out initial break-in oil supply and install fresh filter at 500 miles.
• Adjust hydraulic lifter baseline preload according to factory specification before road deployment.
• Check intake runner flange fasteners for correct sealing torque after the first heat cycle.

Warranty Statement Shipping Crate Contents
