CYLINDER HEAD ASSEMBLY REPAIR - CONTINUED
REPAIR - CONTINUED
Reinstall valves in their designated bores. Measure and record depth H.
Calculate grinding depth (GD) from (G) and (H) measurements as follows: G = H-G
GD=0.010 in. (0.25 mm)
If (GD) is equal to or less than given tolerance, identify valve seat with an X.
If (GD) is greater than 0.010 in. (0.254 mm), a service
valve seat must be installed.
With valves in their designated bores, measure and record depth (I).
0.039 to 0.060 in.
(0.9906 to 1.524 mm)
If depth (I) exceeds tolerance limits, replace the valve and check depth (I) again.
