1. Place cylinder head onto the supports (1).     Align th e supports so that the reaming tool is not able to  
strike the supports when it is pressed through.

2. Insert reaming tool (2)   into the basic bore.   
3. Press reaming tool (2)   through.   Lubricate with   petroleum during this step. Clean reaming tool (2)  
with compressed air or a plastic brush  after each   reaming operation. Use a matching aluminum drift as  
an extension in the area of th  e guide sleeve (3) for pressing th rough the reaming tool (2).

1. Clean bore of valve guide (1)   (never use a hard object).   
2. Inspect surface of bore for scores or signs of rubbi  ng.   If damage to the surface is present, the valve  
guide must be replaced and the valve stem inspected   for uneven areas. If the stem is damaged, the valve  
must be replaced together with the valve guide.

3. If it is possible to inse  rt the side of the hole gauge  (3)   marked with "+220" over its full length (5 mm)  
into the valve guide, it is then necessary to repl  ace the valve guide.   Inspect bore of valve guide in  
longitudinal and tran  sverse direction.
