AR05.30-P-3731-06VT Inspect valve guides

Test and adjustment values for valve guides:

Special Tools:

Component Identification:

1 Clean bore of valve guide (1) (never use a hard object).
2 Inspect surface of bore for scores or signs of rubbing.

If damage to the surface exists, it is necessary to replace the valve guide and to inspect the stem of the valve for uneven areas. If the stem is damaged, the valve must be replaced together with the valve guide.

Component Identification:

3 If it is possible to insert the side of the feeler gage (3) marked with "+220" over its full length (5 mm) into the valve guide, it is then necessary to replace the valve guide.

Inspect bore of valve guide in longitudinal and transverse direction.

The overlap of the valve seat ring in the cylinder head is determined as follows: outside diameter of the valve seat ring (B) minus the basic bore diameter of the valve seat ring in the cylinder head (E).
