4. Reaming basic bore in cylinder head (repair size).- Thoroughly remove carbon deposits in cylinder head.
Notice Particularly remove the insides of the valve seat rings.
- Remove the elevation (arrow) of intake valve seat rings.
- Select correct broaching tool and guide sleeve (refer to the table). Notice Before broaching work, the broaching tool must be cleared of swarf with a stiff plastic brush.
- Lubricate the basic bore, guide sleeve and broaching tool with petroleum.
- Push broaching tool (6) in broaching direction (arrow) into the guide sleeve (7) far enough so that the first cut of thebroaching tool is positioned in the basic bore when guide sleeve is fitted onto the valve seat ring (3).
6. Broaching tool7. Guide sleeve
See the ‘standard data ’
- Center the guide sleeve (7) in the valve seat ring (3) by
turning.
- Knock through the broaching tool (6) with a plastic hammer (approx. 25g). and aluminum drift.
