Precision is everything during a rebuild. Standard torque values are clearly listed for critical fasteners, establishing 37–45 Nm for engine mounting bolts and 9–12 Nm for the exhaust pipe. The cylinder head specification tables note exact intake valve clearances at 0.03–0.08 mm, while total engine oil capacity is documented at 1.2 liters. Extensive exploded-view diagrams illustrate the clutch assembly, gearbox, and cylinder head to ensure your assembly matches the original layout.
