Product Overview

RF8 series is Nissan Diesel classic heavy-duty V8 four-stroke diesel engine featuring ultra-thick reinforced cast iron V-type cylinder block, forged heavy-duty crankshaft & connecting rod, gear-driven valve train and purely mechanical inline plunger injection pump with zero electronic control components.

Two factory original configurations for different heavy-load scenarios:

Naturally Aspirated RF8 Base Version: Simple non-turbo structure, low maintenance cost, strong tolerance to low-grade diesel fuel, stable power for medium-heavy haulage and stationary generator operation
RF08-TB Twin Turbo Intercooler High Power Version: Matched twin turbochargers + air-to-air intercooler, reinforced internal moving parts, significantly improved low-speed pulling torque, dedicated for long-distance full-load highway transport and mining heavy haul trucks

No complex sensors, EGR or electronic modules, extremely low failure rate under high-dust, long-hour continuous heavy-load working conditions. Widely used as aftermarket replacement power for second-hand heavy commercial vehicles and large industrial power equipment across Africa, Middle East, Southeast Asia and Latin America markets.

Fitment Reference

Replacement fit for heavy commercial truck & large industrial machinery chassis compatible with RF8 series powerplant. Reference production year range: 1985–2005

Heavy-Duty Highway Truck

Nissan UD CWB520 semi-trailer tractor head chassis
UD heavy dump truck, bulk cement tanker, fuel transport tanker chassis

Mining & Construction Equipment

Medium-large mining haulage truck, stationary heavy-duty water pump unit chassis

Industrial Power Generation

200–350kW large silent stationary generator set chassis
Mobile heavy welding equipment, large irrigation pump power unit chassis

Important Notice

Two core RF8 series variants with completely non-interchangeable internal & peripheral accessories:

Naturally aspirated RF8: Smooth simple exhaust manifold, no twin turbo oil supply/return pipeline, standard cast piston assembly, basic mechanical pump calibration
Twin turbo RF08-TB: Reinforced forged piston & connecting rod, exclusive twin turbo exhaust manifold, full dual turbo oil pipeline layout, high-flow calibrated fuel pump, large intercooler assembly

Two mounting calibration versions for RF8 series: highway truck lightweight bracket version and mining machinery heavy-duty reinforced thick mounting feet version. Engine support brackets, oversized cooling fan housing and heavy-duty flywheel housing cannot be directly interchanged.

Critical distinction with other UD heavy-duty engines: RD8 V8, RE8 V8, RF10 V10 differ in cylinder block size, crankshaft stroke, mounting layout, completely incompatible chassis swap.
