6.2 DIESEL 6A7-9
Insp ection
1. Inspect the cylinder head for cracks in the exhaust
ports, combustion chambers, or external cracks to the
coolant chamber.
2. Inspect the valves for burned heads, cracked faces or
damaged stems. Inspect deck face for scratches or
dents across gasket fire-ring area. Marks across coolant
seal surfaces can be no deeper than .003 ".
N O T IC E :
Excessive valve stem to bore clearance will
cause excessive oil combustion and may cause valve
breakage. Insufficient clearance will result in noisy and
sticky functioning of the valve and disturb engine
smoothness.
3. Measure valve stem clearance (fig. 6 A 7 -12) as follows:
a. Clamp a dial indicator on one side of the cylinder
head rocker arm cover gasket rail.
b. Locate the indicator so that movement of the valve
stem from side to side (crosswise to the head) will
cause a direct movement of the indicator stem. The
indicator stem must contact the side of the valve
stem just above the valve guide.
c. Drop the valve head about 1/16" (1.6mm ) off the
valve seat.
d. Move the stem of the valve from side to side using
light pressure to obtain a clearance reading. If
clearance exceeds specifications, it will be necessary
to ream valve guides for oversize valves as outlined.
4. Check valve spring tension with Tool J-8056 spring
tester (Fig. 6A 7-13). Springs should be compressed to
the specified height and checked against the
specifications chart. Springs should be replaced if not
with 44 N (10 lbs.) of the specified load (without
dampers).
V A L V E G U ID E BORES
Valves with oversize stem s are available (see
specifications). To ream the valve guide bores for oversize
valves use Tool Set J-7049.
V A L V E SEATS
Reconditioning the valve seats is very important,
because the seating of the valves must be perfect for the
engine to deliver the power and performance built into it.
Another important factor is the cooling of the valve
heads. Good contact between each valve and its seat in the
head is imperative to insure that the heat in the valve head
will be properly carried away.
Several different types of equipment are available for
reseating valves seats. The recom m endations of the
manufacturer of the equipment being used should be
carefully followed to attain proper results.
Regardless of what type of equipment is used, however,
it is essential that valve guide bores be free from carbon or
dirt to ensure proper centering of pilot in the guide.
N O TIC E :
Valve seats are induction hardened. Excessive
stock removal could cause damage to the seat.
V A L V E S
Valves that are pitted can be refaced to the proper
angle, insuring correct relation between the head and stem
on a valve refacing mechanism. Valve stems which show
excessive wear, or valves that are warped excessively should
be replaced. When a valve head which is warped excessively
is refaced, a knife edge will be ground on part or all of the
valve head due to the amount of metal that must be removed
to completely reface. Knife edges lead to breakage, burning
or pre-ignition due to heat localizing on this knife edge. If
the edge of the valve head is less than 1/32" (,80m m ) thick
after grinding, replace the valve (fig. 6 A 7 -1 4 ). Several
different types of equipment are available for refacing
valves. The recommendation of the manufacturer of the
equipment being used should be carefully followed to attain
proper results.
A ssem b ly
1. Insert a valve in the proper port.
2. Assemble the valve spring and related parts as follows:
a. Install valve spring shim on valve spring seat then
install a new valve stem oil seal.
