Technical Specifications and Data

The reference tables define exact factory tolerances for the 1995–2000 production run. Key data points include intake (225°) and exhaust (234°) camshaft timing, a piston-to-cylinder clearance of 0.016–0.034 mm, and a maximum crankshaft bearing radial clearance of 0.1 mm. The electrical section covers the 3-phase AC generator (rated at 12V 280W), while torque sequences for the cylinder head are established at 48 Nm. Note that exceeding these factory wear limits or applying incorrect torque can result in severe engine damage; always double-check measurements and consult a certified mechanic if you are unfamiliar with heavy engine teardowns.
