Fig. 114: Identifying Feeler (102 589 01 23 00)
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.
Fig. 115: Identifying 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.
