The manual also outlines the governor system, cooling components, and electrical output requirements for starter motors and alternators across the various agricultural and industrial engine configurations.

Technical Data and Service Preview

This technical guide contains extensive tolerance charts, tightening torque values, and wear limits for internal components. Main bearing oil clearance for the K3–K4 engine series is specified in the 0.040–0.101 mm range within the crankshaft assembly data. The manual lists cylinder head bolt torque at 10–11 kgm for M10 hardware and 15–16 kgm for M14 hardware on the K4M engine. Injection nozzle starting pressure is documented at 220 kg/cm2 with a service limit of 200 kg/cm2 in the fuel system specifications. Reference values for piston ring gaps and gear backlash after assembly are included to support accurate component installation and engine longevity. All service data shown here is for reference only — qualified technicians and the original OEM documentation remain the authoritative source for any hands-on work. This official OEM workshop manual documents the K3 and K4 series engines, providing specifications for engine components, fuel injection, and cooling systems to assist in the maintenance of agricultural and industrial machinery.
