Complete Workshop Reference

Whether you are running diagnostics in a professional shop or rebuilding a core in your home garage, having accurate factory data is non-negotiable. This reference provides a comprehensive breakdown of the SL-Series, detailing everything from initial component identification to final assembly adjustments. You will find dedicated sections outlining troubleshooting pathways for hard starting, fuel knock, overheating, black exhaust smoke, and erratic idle speeds. The manual meticulously covers the electrical system—including starter and alternator testing—alongside the cooling system and water pump removal. Safety note: Diesel fuel systems operate under extreme pressure. Always review the specialized fuel handling and disassembly precautions outlined in the injection pump chapter before starting any fuel system service.

Essential Technical Data

Precision matters. This document supplies the exact factory specifications required for a successful rebuild and long-term reliability. The assembly section details the correct cylinder head bolt tightening sequences alongside precise torque values, such as the 5.25 ± 0.25 kgf·m (51.5 ± 2.5 N·m) required for the main bearing caps. The text clearly maps out critical tolerances for inspection. This includes timing gear backlash limits (0.30 mm for all standard gear mesh combinations), intake valve clearances (0.02 to 0.05 mm), and standard compression pressures (30 kgf/cm2 for the SL series, 32 kgf/cm2 for the SL2 series). Fluid and pressure data, including the 140 kgf/cm2 injection pressure and specific coolant capacities ranging from 1.8 to 2.5 liters, are fully documented to support the entire build.
