(2) Clean varnish deposits from inside of tappet
body above plunger cap.
(3) Invert tappet body and remove plunger cap,
plunger, flat or ball check valve, check valve spring,
check valve retainer and plunger spring. Check valve
could be flat or ball.
CLEANING AND ASSEMBLY
(1) Clean all tappet parts in a solvent that will
remove all varnish and carbon.
(2) Replace tappets that are unfit for further ser-
vice with new assemblies.
(3) If plunger shows signs of scoring or wear, valve
is pitted, or valve seat on end of plunger indicates any
condition that would prevent valve from seating, in-
stall a new tappet assembly.
(4) Assemble tappets (Fig. 26).
INSTALLATION
(1) Lubricate tappets.
(2) Install tappets in their original positions.
(3) With roller tappets, install aligning yokes with
(Fig. 26).
(4) Install yoke retainer and torque screws to 12
N
z
m (105 in. lbs.) (Fig. 25).
(5) Install cylinder heads. Refer to cylinder head
installation of this section for procedure.
(6) Start and operate engine. Warm up to normal
operating temperature.
CAUTION: To prevent damage to valve mechanism,
engine must not be run above fast idle until all
hydraulic tappets have filled with oil and have be-
come quiet.
VALVE TIMING
(1) Remove front valve cover and all 6 spark plugs.
(2) Rotate engine until the #2 piston is at TDC of
the compression stroke.
(3) Install a degree wheel on the crankshaft
damper.
(4) With proper adaptor, install a dial into #2 spark
plug hole. Using the indicator find TDC on the com-
pression stroke.
(5) Position the degree wheel to zero.
(6) Remove dial indicator from spark plug hole.
(7) Place a 5.08 mm (0.200 inch.) spacer between
the valve stem tip of #2 intake valve and rocker arm
pad. Allow tappet to bleed down to give a solid tappet
effect.
(8) Install a dial indicator so plunger contacts the
#2 intake valve spring retainer as nearly perpendicu-
lar as possible. Zero the indicator.
(9) Rotate the engine clockwise until the intake
valve has lifted 0.254 mm (0.010 inch.).
CAUTION: Do not turn crankshaft any further clock-
wise as intake valve might bottom and result in
serious damage.
(10) Degree wheel should read 3 degrees BTDC to 4
degrees ATDC.
TIMING CHAIN COVER, OIL SEAL AND CHAIN
COVER
REMOVAL
(1) Disconnect battery. Remove fan module.
(2) Drain cooling system. Refer to Cooling System
Group 7 for procedure.
(3) Raise vehicle on hoist. Drain engine oil.
