4.2.7 Valve guide replacement
1) Use a valve guide extraction tool(12.1-1 in
Chapter 12) and extract the valve guide from the
cylinder head.
2) Put liquid nitrogen or ether (or alcohol) with dry
ice added in a container and put the valve guide
for replacement in it for cooling. Then insert it in
with a valve guide inserting tool (Refer to No.2 of
4.1.2 in Chapter 4).
Do not touch the cooled valve guide with bare hands
to avoid skin damage.
3) Check the inside diameter and finish to the
standard inside diameter as required with a
reamer.
