VEGE Remanufactured DDK8 4.7L 287ci Car Truck Long Block Engine

Description

Dropped valve seats from mild overheating and broken secondary timing tensioner arms destroy commercial fleet utility truck engines. The VEGE Remanufactured DDK8 Long Block Engine stops catastrophic valvetrain collapse through an industrial engine rebuild protocol. This 4.7L 287ci 8-Cylinder powerplant produces 235HP. Mechanics must verify the crankshaft tone ring tooth count matches vehicle computer requirements before installing the flywheel.

ASTM A48 Class 35 gray iron forms the deep skirt block structure with cast-in cross bolted main bearing caps. The VEGE engine core features an induction hardened nodular iron crankshaft, forged connecting rods, and coated hypereutectic pistons. Initial starter draw consumes 165A on standard 12V starting circuits. Dry weight measures 485 lbs with dimensions of 27in length, 26in width, 27in height backed by a 6.0 quarts oil pan.

Key Features of VEGE DDK8

Fleet managers buy VEGE DDK8 Long Block Engine packages to keep municipal service trucks on predictable route schedules. CNC cylinder head machining incorporates high interference-fit valve seats to stop dropped seats during each commercial long block repower.

• 8-Cylinder deep skirt iron block uses cross bolted main caps for extreme bottom end rigidity under load.
• 16-Valve single overhead cam heads feature oversized interference-fit valve seats to prevent seat drop.
• 4.7L displacement delivers 295 ft-lbs torque across steady commercial hauling speed bands.
• 0.0014in rod journal clearance preserves fluid film strength under continuous highway operation.
• Upgraded timing chain tensioner arms resist embrittlement and stop secondary chain slap.
• Induction hardened camshaft journals prevent galling in aluminum cylinder head cam towers.
• DDK8 commercial core assemblies arrive with brand new high pressure oil pump units.

Dynamometer Operating Tolerance Data

Hot cell brake tests establish 235BHP and 295 ft-lbs torque at 4800 RPM on the DDK8 long block engine. Standard diagnostic sensors verify 50 PSI oil gallery pressure at 195°F oil bath operating temperature under full load. Cylinder compression gauges record 180 PSI across all eight bores with variance confined under 3% between cylinder banks. Pyrometer probes indicate 1180°F peak exhaust temperature under dyno brake loads. Precision bench dial indicators confirm crankshaft thrust runout remains below 0.0003in TIR across finished surfaces.

Field Installation Directives Constraints

Mechanical throttle cable return springs demand 5 lbs manual pull effort to actuate the throttle body shaft during pedal travel. This engine is not built for supercharged track vehicles, marine inboard hulls, or high output dual plug configurations.

• Drain initial break-in petroleum motor oil at 500 miles and replenish the crankcase with API approved 5W-30 mineral oil.
• Stationary hydraulic lash adjusters maintain continuous zero lash operation without periodic shimming.
• Torque-to-yield cylinder head bolts require complete discard and new fastener installation on every service teardown.

Warranty Protection Transport Manifest

Commercial vehicle investments receive coverage under the VEGE assembly standard 3-Year 100,000-mile warranty policy. Each heavy timber shipment crate contains the complete assembled remanufactured long block, front timing cover, stamped steel oil pan, composite valve covers, oil pump pickup tube, and signed dyno performance test sheets.
