VEGE Remanufactured DF82 7.5L 460ci Premium Grade Long Block Engine

Description

Timing chain slack and exhaust manifold stud shearing end upon mounting the VEGE Remanufactured DF82 7.5L Long Block Engine. Outputting 245HP from a 460ci 8-Cylinder commercial long block repower layout, this unit drives commercial medium-duty wreckers. Installers must confirm distributor gear metallurgy pairing to match the flat-tappet cast camshaft before final ignition distributor installation.

Cast from heavy ASTM A48 Class 35 gray iron, the massive crankcase provides structural strength to resist torsional bending under severe cargo loads. The VEGE engine core utilizes induction-hardened nodular iron crankshaft journals and stellite exhaust valves. Cranking starter demand requires 12V 185A. Engine dry weight measures 620 lbs inside a 30in length, 27in width, 29in height chassis envelope holding 6.0 quarts oil.

Key Features of VEGE DF82

Commercial transport fleets buy VEGE DF82 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 double roller timing chain set eliminates timing retard caused by chain stretch.
• 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 55 PSI line pressure across demanding fleet hauling duty.
• DF82 commercial core architecture incorporates deep-skirt main bearing caps for crankcase rigidity.
• Tri-metal copper-lead bearings establish 0.0016in running clearance to protect crank journals from wear.

Bench Dynamometer Load Calibration Data

Certified dyno testing confirms 245 continuous BHP and 395 ft-lbs torque output at 3600 RPM continuous test load. Pressure gauges register 55 PSI oil gallery pressure at 195°F oil sump temperature, while exhaust gas temp levels off at 1250°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 DF82 long block engine.

Field Service Guidelines Operating Boundaries

Mechanical throttle lever operation takes 5 lbs pull force through the linkage bracket assembly. This power unit is NOT engineered 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 lifter preload depth between 0.040in and 0.050in before sealing valve covers.
• Verify cylinder head bolt clamping torque using factory angle-gauge procedures after initial run.

Warranty Statement Wood Crate Inventory

Manufacturing adheres strictly to VEGE assembly standard metrics backed by a 3-Year 100,000-mile fleet warranty. The wood freight box contains the remanufactured long block assembly, stamped steel oil pan, front timing cover, stamped valve covers, oil pump pickup tube, and completed dyno test sheet.
