Eliminate recurring valvetrain wear with the VEGE 552 Car Truck Long Block Engine built for commercial long block repower projects in light delivery trucks. This 2354cc 4-Cylinder assembly produces 160HP through dual overhead camshafts and chain driven valvetrain geometry. Mechanics must check balance shaft chain timing during assembly because incorrect balance phase creates severe secondary vibration through chassis crossmembers.

Cast from A356-T6 aluminum alloy with cast iron cylinder sleeves, the engine block connects to a high flow aluminum cylinder head. Each VEGE engine core undergoes magnetic particle crack testing, deck milling within 0.0002in flatness, and line boring. A 12V starter system draws 175A under cold cranking tests. Unrigged dry weight registers 315 lbs across a 26in length by 23in width by 25in height mounting stance. Sump capacity holds 4.5 quarts of 5W-20 oil.

Key Features of VEGE 552

Fleet operators buy VEGE 552 Car Truck Long Block assemblies to complete an industrial engine rebuild with minimum mechanical downtime. Precision remanufacturing operations restore every moving component to tight factory manufacturing limits.

- 2354cc displacement produces 161 ft-lbs torque across demanding commercial route cycles.
- Dual overhead camshaft chain drive controls 16 valves with precision ground valve faces.
- The 552 commercial core receives diamond cylinder hone processing for rapid ring seating.
- Forged steel crankshaft journals undergo micro polishing to reduce journal drag under load.
- Hypereutectic aluminum alloy pistons feature graphite coated skirts to eliminate cold scuffing.
- High strength multi layer steel head gaskets seal combustion chambers against blow by under load.
- Lower balance shaft assembly isolates engine harmonic vibration from the truck cab.

Dynamic Load Bench Tolerances

On the water brake dynamometer, the 552 long block engine produces 160 continuous BHP at 6,000 RPM and 161 ft-lbs torque at 4,400 RPM. Oil gallery pressure maintains 55 PSI under high operating heat with sump temperatures stabilized at 195°F. Pyrometer gauges measure exhaust gas heat levels below 1,240°F under sustained brake load. Compression testing confirms 190 PSI across all 4 cylinders with under 3% variance. Crankshaft journal runout remains below 0.0003in TIR, keeping main bearing oil clearances between 0.0011in and 0.0017in.

Field Service Maintenance Rules

Throttle cable action requires 5 lbs pull force to actuate the intake butterfly without stickiness. Do not install this 2.4L car truck replacement engine into marine inboard hull cavities or severe duty stationary pumps that require constant wide open throttle.

- Change motor oil and spin on filters every 3,000 miles or 150 run hours with 5W-20 specification oil.
- Inspect timing chain tensioner travel and check valve lash every 15,000 miles to factory cold specs.
- Retorque cylinder head fasteners to 68 ft-lbs after the initial 50 operating hours of break in run.
