• Engine service data detailing piston ring side clearance, valve stem diameter, and crankshaft run-out tolerances

Component and System Documentation

This manual lays out the core technical data needed for vehicle identification, machine dimensions, and routine maintenance intervals. Whether you are working on the air-cooled TM or the liquid-cooled 4x4 and 6x6 platforms, dedicated sections provide exact parameters for lubrication, cooling system pressure tests, and electrical component diagnostics. You will find precise factory requirements for fuel delivery systems, transmission gearcase service, and steering alignment. Before tearing into the chassis, always review the battery isolation steps and jack-point load limits detailed early in the text to maintain a safe shop environment.

Engine Specification Highlights

The guide dives deep into the EH63, EH42, and EH50 powerplants. It outlines crucial valve clearance specifications, piston-to-cylinder tolerances, and torque values for both cylinder head and crankshaft installation. Technicians get exact wear limits for the connecting rod big end, valve stems, and crankshaft journals to accurately gauge component life. For example, the specification tables list the intake and exhaust valve clearance for the 2x4, 4x4, and 6x6 at a precise 0.10–0.15 mm. Torque values are explicitly mapped out. The TM model requires 14 ft. lbs. for the oil filter and engine drain plugs. Spark plug torque runs 8.7–10.8 ft. lbs. for new plugs, shifting to 16.6–19.5 ft. lbs. for reused ones.
