Attention.
- If the camshaft is rotated after the drive chain is removed, the valves may hit the piston crown when the piston is at top dead center, causing engine damage. When rotating the camshaft with the drive chain removed, all pistons in the engine must be set to the middle position.
- When turning the camshaft with a wrench on the hexagonal part, the wrench may hit the rocker arm and damage it. To prevent damage to the rocker arm, when holding the camshaft by the hexagonal part, place the wrench closer to the rear of the engine, as shown in the figure, to ensure a safe gap between the wrench and the camshaft lobe.
Note: The width of the hexagonal part of the camshaft is 22-24mm.
