VEGE Remanufactured DFK2 7.5L 460ci Industrial Grade Long Block Engine

Description

Sustained heavy equipment towing routes mandate the VEGE DFK2 Long Block Engine, built to conquer demanding commercial long block repower cycles in heavy wreckers and dump trucks. This 7.5L 460 cid 385 Series Big Block Ford creates 245HP at 4,000 RPM and 395 ft-lbs torque. Technicians must check exhaust port bolt thread condition because thermal expansion can strip factory threads.

Solid ASTM A48 Class 35 cast iron shapes the massive 90° big block casting. A cast nodular iron crankshaft pairs with forged steel connecting rods inside this VEGE engine core. Starter draw measures 185A on standard 12V fleet circuits. Dry weight totals 640 lbs within an envelope of 31in length by 28in width by 30in height. Sump holds 6.0 quarts.

Key Features of VEGE DFK2

Commercial contractors buy VEGE DFK2 Long Block Engine assemblies to shorten shop backlogs during an industrial engine rebuild schedule. High precision hone finishes establish an optimal crosshatch pattern for immediate ring seating.

• Heavy duty cast iron cylinder heads feature large ports to promote continuous low speed pulling torque.
• A flat tappet or hydraulic roller camshaft profile maintains broad power bands under heavy loads.
• Hypereutectic pistons resist thermal growth to eliminate bore scuffing under full payload towing.
• The DFK2 commercial core holds 0.0018in connecting rod bearing clearance for oil film durability.
• Deep main bearing webs provide bottom end structural rigidity against extreme rotational torque.
• High output oil pumps supply constant lubrication volume to internal galleys to prevent journal wear.
• Multi layer steel head gaskets clamp compression tight across the entire deck surface.

Bench Dyno Parameters Thermal Thresholds

Dynamometer testing confirms 245HP at 4,000 RPM plus 395 ft-lbs torque at 2,400 RPM for this DFK2 long block engine. Gauge monitors record 55 PSI oil gallery pressure at 2,000 RPM at 195°F operating temperature. Cylinder compression gauges verify 175 PSI across all eight cylinders within 4% balance. Crankshaft center journal runout shows 0.0003in TIR. Exhaust gas temperature gauges indicate 1,220°F during extended dyno pulls.

Installation Protocols Maintenance Schedule Directives

Manual throttle return springs demand 5 lbs linkage pull tension for positive closure against engine vibration. Mechanics must avoid this commercial replacement engine for light vehicle chassis lacking structural crossmembers for 640 lbs engine blocks or vehicles with low capacity cooling cores.

• Drain break in oil after 500 miles or 30 operating hours then refill with 15W-40 heavy duty motor oil.
• Inspect exhaust manifold mounting flanges for flatness prior to installing exhaust gaskets.
• Check cylinder head fasteners in three passes reaching 135 ft-lbs final specification.

Crate Manifest Warranty Protection Details

Every long block carries the VEGE build standard with 3-Year or 100,000-mile parts coverage. The freight crate encloses the long block core, oil pan, front timing cover, valve covers, oil pump pickup, plus official plant signed inspection documents.
