Part of the Isuzu 6HK1 engine documentation.
This Isuzu Workshop Manual covers the AA-6HK1T and BB-6HK1T industrial diesel engines, the 7.790 L turbocharged six-cylinder units built for the 2000 model year. It runs 241 pages with a searchable text layer, so specs and procedures are easy to find and copy.
The manual is organised by Isuzu section codes: General Information with torque and service standards, Engine Mechanical, Engine Cooling, Engine Fuel, Starting and Charging, Engine Lubrication, and Engine Induction. Each area walks through service precautions, general description, disassembly, inspection and reassembly.
Use it to torque the cylinder head, service the turbocharger, rebuild the water pump and thermostat, set injection nozzle opening pressure, or overhaul the alternator. Exact clearances, torque values and step by step procedures are included throughout. Buy once, download instantly, and print the pages you need for the workshop.
