EXAMINING VALVE CLEARANCE
| Cylinder head cover | remove, install (01-0500) . |
| Cam at relevant bucket tappet | position to base circle (lobe of cam must face up). |
| Bucket tappet | press with suitable tool (not steel tool). |
| If one bucket tappet can be pressed more easily in comparison to the others | replace this bucket tappet. |
COMPARISON BUCKET TAPPET
| Relevant camshaft | remove, install (05-2200) . |
| Bucket tappet of respective cylinder | pull up with rubber suction cup and remove. Install the first version of bucket tappet only together with double valve springs. Do not use magnets as minute iron particles collect at the magnetized contact surfaces of the bucket tappet and cause damage to the buckets and cams. The bucket tappets must be re-installed at the same point. The contact surface must not have any pitting caused by the cam lobe so that the rotational movement of the bucket tappet is not obstructed. |
| Basic bore | perform visual inspection. |
COMMERCIALLY AVAILABLE TOOL
| 30 mm dia. rubber suction cup | e.g. | Hazet, no. 735-2 |
