VALVE GUIDES
INSPECTION
● Insert the valve guide reamer from the combustion
chamber side and ream the guide to remove any carbon
build-up before measuring the guide.
TOOL : VALVE GUIDE REAMER
● Measure and record each valve guide inner diameter.
SERVICE LIMIT : 5.030 mm
● Measure the guide-to-stem clearance with a dial
indicator while rocking the stem in the direction of
normal thrust.
SERVICE LIMIT : IN : 0.090 mm
EX: 0.120 mm
● Measure the inner diameter of the new valve guide. If
the clearance is not within the service limit, replace the
valve.
REPLACEMENT
● Heat the cylinder head to 130°C - 140°C (275°F - 290°F).
● Support the cylinder head and drive the old guides out
of the combustion chamber side of the cylinder head.

giude out.
!
NOTE
△
●Do not heat the cylinder head beyond 150°C (300°F).
●Use temperature indicator sticks, available from
welding supply stores, to be sure the cylinder head is
heated to the proper temperature.
●Using a torch to heat the cylinder head may cause
warping.
●Wear insulated gloves to avoid burns when handling
the heated cylinder head.
●Refinish the valve seats whenever the valve guides are
replaced to prevent uneven seating.
