1D-33 Engine Mechanical:
Valve stem end deflection limit
In: 0.14 mm (0.005 in.)
Ex: 0.18 mm (0.007 in.)
Valves
• Remove all carbon from valves.
• Inspect each valve for wear, burn or distortion at its
face and stem end, as necessary, replace it.
• Measure thickness “a” of valve head. If measured
thickness exceeds limit, replace valve.
Valve head thickness (In and Ex)
Standard: 1.25 – 1.55 mm (0.049 – 0.061 in.)
Limit: 0.9 mm (0.035 in.)
• Inspect valve stem end face for pitting and wear. If
pitting or wear is found there, valve stem end may be
resurfaced, but not so much as to grind off its
chamber. When it is worn out too much that its
chamber is gone, replace valve.
• Check each valve for radial runout with a dial gauge
and “V” block. To check runout, rotate valve slowly. If
runout exceeds its limit, replace valve.
Limit on valve head radial runout
0.08 mm (0.003 in.)
• Seating contact width:
Create contact pattern on each valve in the usual
manner, i.e., by giving uniform coat of marking
compound to valve seat and by rotatingly tapping seat
with valve head. Valve lapper (tool used in valve
lapping) must be used.
Pattern produced on seating face of valve must be a
continuous ring without any break, and the width of
pattern must be within specified range.
Standard seating width “a” revealed by contact
pattern on valve face
Intake and Exhaust: 1.1 – 1.3 mm (0.0433 – 0.0512
in.)
