VEGE Remanufactured DFZE 2.0L 121ci Compact Car Long Block Engine

Description

Timing belt idler bearing seizure and plastic thermostat housing warping resolve once fleet technicians choose the VEGE Remanufactured DFZE 2.0L Long Block Engine. Delivering 130HP from its 121ci 4-Cylinder commercial long block repower format, this unit powers commercial transit equipment. Mechanics must check the exhaust camshaft variable timing solenoid screen for debris contamination prior to installing upper cam covers.

Dense ASTM A48 Class 30 gray iron forms the engine block, matching an ASTM A356-T6 cast aluminum cylinder head for balanced heat dissipation. The VEGE engine core incorporates induction-hardened nodular iron camshaft lobes paired with stellite valve faces. Cranking starter draw pulls 12V 140A. Total dry weight measures 245 lbs within a 21in length, 20in width, 23in height chassis envelope holding 4.2 quarts oil.

Key Features of VEGE DFZE

Independent repair garages buy VEGE DFZE commercial long block configurations to eliminate repeat comebacks from overheated cylinder heads. Machinists enforce strict industrial engine rebuild manufacturing parameters during every remanufacturing phase.

• Forged alloy steel crankshaft features induction-hardened radii holding a strict 0.0002in TIR runout limit.
• Cast ductile iron cylinder walls receive fine diamond plateau crosshatch hone for long ring life.
• Tri-metal bearings establish 0.0012in hydrodynamic running clearance to protect crank journals from wiping.
• Precision deck surfacing establishes 0.0002in flatness to prevent fire ring failure under heavy engine loads.
• High-flow internal trochoid oil pump delivers 45 PSI galley pressure to lubricate overhead camshaft bearings.
• DFZE commercial core casting features thick cylinder bore walls to resist oval deformation under heat.
• Hypereutectic aluminum pistons reduce skirt expansion while resisting top ring microwelding under heavy load.

Bench Dynamometer Load Operating Limits

Automated test dynos confirm 130 continuous BHP and 130 ft-lbs torque output at 5300 RPM continuous sweep calibration. Monitoring displays 45 PSI galley pressure at 190°F oil sump temperature, while exhaust gas temp peaks at 1190°F under maximum test pull. Cylinder compression measures 185 PSI across all four cylinders within 3% balance. Crankshaft runout checks at 0.0002in TIR on the DFZE long block engine.

Installation Requirements Negative Filter Rules

Throttle spool return resistance measures 4 lbs force on the bracket return spring. This power plant is NOT engineered for turbo installations without forged piston upgrades or heavy stationary generator use. Installation technicians must execute verified startup maintenance protocols without exception.

• Drain break-in crankcase oil supply and replace filter element at 500 miles.
• Verify solid bucket tappet cold lash at 0.008in intake and 0.012in exhaust before road tests.
• Check all lower timing cover perimeter bolts for correct sealing torque after the first thermal cycle.

Warranty Statement Wood Crate Inventory
