Crankcase
| Machining | |||
|---|---|---|---|
| Only machine cylinder head contact surface if cylinder liners have been inserted, porous or damaged points are present or if an impermissible variation of the flatness in the longitudinal direction is measured. The stock removal at the cylinder head and at the crankcase must together be not more than 0.5 mm. After machining the crankcase contact surface, install a repair cylinder head gasket (1.85 mm thick before being compressed). |
