Tappet bore diameter in cylinder head 30.000 – 30.021 mm. Tappet-to-bore clearance 0.025 – 0.061 mm. Valve clearance: Cold engine (*): – intake valves 0.25 – 0.33 mm – exhaust valves 0.32 – 0.40 mm. Hot engine: – for inspection: • intake valves 0.21 – 0.49 mm • exhaust valves 0.30 – 0.58 mm – for adjustment: • intake valves 0.32 – 0.40 mm • exhaust valves 0.37 – 0.45 mm. (*) Valve clearance is to be checked only on a hot engine. The manufacturer specifies standard clearances for both warm and cold engine. Cold engine clearances are checked only before starting the engine after major overhaul. After the engine has warmed up, check the clearances again. Lubrication System: Oil pump type: gear type, driven by crankshaft nose. Minimum oil pressure at operating engine temperature: – at idle 0.49 – 1.86 kgf/cm² – at 3000 rpm 3.43 – 4.41 kgf/cm².
