2. Thoroughly clean the basic bore by using a cylinder brush.
Cylinder Brush 000 589 10 68 00
3. Check the basic bore in cylinder head for scoring marks
and ream to next repair size if necessary.
2. Insert the GO/NO GO gauge into the valve guide bore. If
the NO GO side is inserted fully, replace the valve guide
(Intake 8mm, Exhaust 9mm).
GO/NO GO Gauge 601 589 02 23 00
Replacement Procedure
1. Drive out the valve guide (2) by using a drift (5).
Notice
The valve guide must be driven out upward of the cylinder
head.

Checking
1. Thoroughly clean the valve guide bore using a cylinder
brush.

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 the
broaching tool is positioned in the basic bore when guide
sleeve is fitted onto the valve seat ring (3).
6. Broaching tool
7. 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.

8. Check the valve guide bore with GO / NO GO gauge (9).
The GO side (marked ‘0’) should just still drop. If the GO
side cannot be inserted, the bore of valve guide should be
reamed.
Notice
Perform the check only on cooled down cylinder head.

6. Cool down the new valve guide (2) with liquid nitrogen.
Notice
Do not touch the cooled valve guide by hand.

7. Drive in new valve guide with drift (8) until the wire ring makes
contact.
Notice
The valve guide must be driven in from the cylinder head
cover.
