Replacing
CAUTION!
Cylinder heads with valve seats that can no
longer be refaced, or which have already
been machined to the minimum dimension,
should no longer be repaired.
CAUTION!
When the shoulder on the new guide makes contact, the pressing
force must not exceed 1.0 ton or the guide shoulder could break off. - Press out worn valve guides from camshaft side using drift 10-206.
(Replacement guides with shoulder must be pressed out from
combustion chamber side.)
- Coat new guides with oil and, using drift 3121, press into cold cylinder
head from camshaft side until shoulder makes contact.
- Use 7mm reamer 3120 to ream new valve guides to size, using plenty
of cutting fluid.
