VEGE Remanufactured 852C 1.8L 1794cc Compact Car Long Block Engine

Description

Bore ovalization and high oil consumption through seized oil rings terminate when workshops mount the VEGE Remanufactured 852C 1.8L Long Block Engine. This 1794cc 4-Cylinder commercial long block repower solution provides 125HP for regional commercial transit fleets. Mechanics must check timing chain tensioner O-ring placement to stop persistent external oil drips down the block.

An ASTM A356-T6 aluminum block incorporates centrifugally spun iron liners to minimize total mass while maintaining cylinder stability. The VEGE engine core features redesigned piston oil drain passages to prevent ring carbon gumming. Cranking starter draw demands 12V 140A. Total dry weight measures 225 lbs within a 21in length, 19in width, 23in height stance holding 4.2 quarts oil.

Key Features of VEGE 852C

Fleet dispatch managers buy VEGE 852C commercial long block engines to restore aging fleet fuel mileage. Factory manufacturing lines follow documented industrial engine rebuild protocols throughout production.

• Forged carbon steel crankshaft features micro-polished journal surfaces holding 0.0002in TIR runout tolerance.
• Redesigned aluminum pistons incorporate oversized oil return passages to eliminate carbon ring packing.
• Diamond-honed iron cylinder walls promote immediate piston ring seating during initial startup.
• CNC milled deck surfaces achieve 0.0002in flatness to stop coolant passage migration under load.
• Dual overhead camshafts feature polished bearing journals to prevent top-end galling under heat.
• 852C commercial core casting includes thick perimeter ribs to dampen excessive high-frequency vibrations.
• Bi-metal aluminum-tin bearings deliver 0.0012in oil clearance to protect journal surfaces from wear.

Bench Dynamometer Load Operating Limits

Dyno testing validates 125 continuous BHP with 125 ft-lbs torque output at 4800 RPM continuous load benchmark. Internal oil gallery pressure measures 45 PSI at 190°F oil sump temperature, while exhaust gas temp stabilizes at 1180°F under dyno pull. Technicians confirm cylinder compression at 185 PSI across all four cylinders within 3% variance. Crankshaft main journal runout measures 0.0002in TIR on the 852C long block engine.

Field Service Directives Maintenance Rules

Throttle spool return resistance registers 4 lbs force on the bracket return spring. This engine is NOT manufactured for turbocharged racing modifications or flex-fuel high-ethanol fuel mixtures. Shop mechanics must observe verified commercial engine service procedures without exception.

• Drain break-in crankcase oil supply and replace filter element at 500 miles.
• Measure cold bucket tappet clearances at 0.008in intake and 0.012in exhaust before road testing.
• Check water pump mounting fasteners for correct torque seal after initial operating heat cycle.
