• Engine mechanical disassembly, inspection, repair and assembly
• Engine lubrication and cooling systems
• Diesel fuel-injection pump, nozzle and related fuel-system service
• Special service tools and their applications

Engine Mechanical Repair Coverage

The engine-mechanical section takes the engine from component identification through disassembly, inspection, repair and reassembly. Illustrated procedures cover the cylinder head, valves and valve mechanism, rocker shaft, cylinder block and liner, pistons and piston pins, connecting rods, crankshaft, bearings, camshaft, flywheel, front plate and gear train. The manual also provides service-data tables, inspection and adjustment criteria, tightening torques and special-service-tool information.

Maintenance & Troubleshooting

The maintenance section includes valve-clearance adjustment, drive-belt inspection, compression-pressure testing, injection timing and idle/max-speed adjustment, injection-nozzle checks, air-cleaner servicing, fuel-filter and water-draining procedures, coolant and engine-oil service, injection-pump lubrication and glow-plug checks. Troubleshooting flow charts address conditions including difficult starting, unstable idle, excessive white or black smoke, low power, water leakage, oil leakage, overheating, an engine that will not stop and abnormal engine noise.

Lubrication & Cooling System Service

Dedicated coverage includes lubrication and cooling circuits, oil pump removal and inspection, oil filters and brackets, oil cooler service, piston and gear-train oil jets, water-pump service, thermostat inspection, radiator servicing and associated service-data specifications.

Fuel Injection System Coverage

The fuel section provides extensive illustrated service information for diesel injection equipment. Coverage includes Diesel Kiki-Bosch in-line and VE-type injection pumps, pump removal and installation, adjustment, disassembly and assembly, testing, fuel-system bleeding, injection nozzles, fuel filters, crankcase-emission-control information and detailed service specifications. The manual also shows special tools and component diagrams used during pump and nozzle work.

Why This Manual Is Useful

This manual brings together the mechanical procedures, service limits, adjustment data, diagnostic charts and fuel-system information needed when maintaining or repairing an SD-series Nissan diesel engine. The numerous diagrams, exploded component views, torque values and inspection procedures make it particularly useful when disassembling components, checking wear, setting adjustments or tracing an engine-performance problem.
