VEGE Remanufactured DFZ8 4.0L 245ci Multi Purpose Long Block Engine

Description

Rear timing cassette guide bracket failure and plastic thermostat housing fracturing cease after technicians install the VEGE Remanufactured DFZ8 4.0L Long Block Engine. Supplying 210HP from its 245ci 6-Cylinder commercial long block repower format, this unit powers commercial utility fleet vans. Installers must verify rear jackshaft timing chain guide clearance before installing the transmission adapter plate.

Cast from heavy ASTM A48 Class 35 gray iron with aluminum cylinder heads, this engine resists warping under load. The VEGE engine core utilizes induction-hardened nodular iron camshaft lobes paired with stellite exhaust valves. Cranking starter demand requires 12V 165A. Engine dry weight measures 395 lbs inside a 25in length, 24in width, 26in height mounting stance holding 5.0 quarts oil.

Key Features of VEGE DFZ8

Municipal utility fleets buy VEGE DFZ8 commercial long block packages to restore long-distance route fleet dependability. Modern clean-room shops enforce verified industrial engine rebuild benchmarks throughout each production cycle.

• Cast nodular iron crankshaft features micro-polished journal surfaces with 0.0003in TIR runout tolerance.
• Reinforced composite timing cassette guide brackets prevent catastrophic rear chain detachment under load.
• 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 52 PSI line pressure across demanding fleet highway duty.
• DFZ8 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.

Dynamometer Load Verification Bench Data

Test cell dynamometers certify 210 continuous BHP paired with 254 ft-lbs torque output at 4200 RPM continuous test load. Fluid sensors record 52 PSI galley oil pressure at 195°F oil sump temperature, while exhaust gas temp settles at 1220°F under maximum pull. Cylinder pressure gauges verify 180 PSI compression across every cylinder within a 3% tolerance. Crankshaft runout registers 0.0003in TIR on the DFZ8 long block engine.

Field Service Directives Maintenance Rules

Mechanical throttle linkage requires 5 lbs pull effort on the throttle cam pivot assembly. This powertrain is NOT manufactured for transverse vehicle platforms or vehicles equipped with mechanical flat-tappet conversion systems. Fleet service technicians must execute standardized shop protocol during checkout.

• Drain break-in engine oil reservoir and replace oil filter at 500 miles or 30 hours.
• Check hydraulic timing chain tensioner bleed-down clearance prior to front timing cover sealing.
• Check lower intake manifold retention bolts after the initial two operating cycles.

Warranty Statement Wood Crate Inventory

Engine remanufacture follows VEGE assembly standard procedures protected by a 3-Year 100,000-mile fleet warranty. The enclosed wood crate contains the fully assembled long block, stamped sheet-metal oil pan, front timing cover, stamped valve covers, oil pickup tube, and an inspector-certified dyno test document.
