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.

Drift (for Exhaust) 103 589 02 15 00
Checking
1. Thoroughly clean the valve guide bore using a cylinder
brush.

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.
GO / NO GO Gauge (for Intake) 102 589 00 23 00
GO / NO GO Gauge (for Exhaust) 117 589 03 23 00
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.
Drift (for Intake) 601 589 05 15 00
Drift (for Exhaust) 601 589 06 15 00
5. Heat the cylinder head (1) in a wear tank to approx. 80°C.
