VALVES & SEATS - INTAKE/EXHAUST
DESCRIPTION
DESCRIPTION - VALVE GUIDES
The valve guides are made of powdered metal and are pressed into the cylinder head. The guides are not replace-
able or serviceable, and valve guide reaming is not recommended. If the guides are worn beyond acceptable limits,
replace the cylinder heads.
DESCRIPTION
Both the intake and exhaust valves are made of steel. The intake valve is 50.93 mm (2.00 inches) in diameter and
the exhaust valve is 39.53 mm (1.55 inches) in diameter. All valves use three bead lock keepers to retain the
springs and promote valve rotation.
STANDARD PROCEDURE - REFACING
NOTE: Valve seats that are worn or burned can be reworked, provided that correct angle and seat width are
maintained. Otherwise the cylinder head must be replaced.
NOTE: When refacing valves and valve seats, it is important that the correct size valve guide pilot be used
for reseating stones. A true and complete surface must be obtained.
1. Using a suitable dial indicator measure the center of the valve seat Total run out must not exceed 0.051 mm
(0.002 in).
2. Apply a small amount of Prussian blue to the valve seat, insert the valve into the cylinder head, while applying
light pressure on the valve rotate the valve. Remove the valve and examine the valve face. If the blue is trans-
ferred below the top edge of the valve face, lower the valve seat using a 15 degree stone. If the blue is trans-
ferred to the bottom edge of the valve face, raise the valve seat using a 65 degree stone.
3. When the seat is properly positioned the width of the intake seat must be 1.018 - 1.62 mm (0.0464 - 0.0637 in.)
and the exhaust seat must be 1.48 - 1.92 mm (0.058 - 0.075 in.).
4. Check the valve spring installed height after refacing the valve and seat.Theinstalledheightforbothintakeand
exhaust valve springs must not exceed 46.0 mm (1.81 in.).
