Camshafts
Inspection
NOTE:
. Do not rotate the camshaft during inspection.
. Removg the rocker arms and rocker shafts.
'L Put the camshafts and camshaft holders on the cylin-
der head. and then tighten the bolts to the specified
torque.
Specified Torque:
O -@: 8 mm botts 27 N.m {2.8 kgf.m,20 lbt'ft)
Apply engine oil to the threads,
O - @: 6 mm bolts 9.8 N.m (1.0 kgf m, 7.2 lbf'ft)
Seat the camshaft by pushing it toward the distribu-
tor end of the cylinder head.
Zero the dial indicator against the end of the distrib-
utor drive. then push the camshaft back and fonh
and read the end play.
Camshaft End Play:

4.Remove the bolts. then remove the camshaft hold-
ers from the cylinder head.
- Lift the camshaft out of the cylinder head, wipe
clean, then inspect the lift ramps. Replace the
camshaft if lobes are pitted, scored, or excessively
- Clean the camshaft bearing surfaces in the cylin
der head, then set the camshaft back in place,
- Insert a plastigage strip across each iournal.
Put the camshaft on the cylinder head. then install
the camshaft holders, and then tighten the bolts to
the specified torque as shown in the left column on
this page.
Remove the camshaft holders, then measure the
widest portion of the plastigage on each journal.

Installation
lnstall the cylinder head in the reverse order of removal:
NOTE:
. Always use a new head and manifold gasket.. The cylinder head gasket is a metal gasket, Take carenot to bend it.
. Rotate the crankshaft, set the No. 1 piston at TDC (seepage 6-63).
. Do not use the middle cover and lower cover forstorang removed items.. Clean the middle cover and lower cover before instal_lation.
o Replace any washers that are damaged or deteriorated.
1. Install the cylinder head gasket, dowel pins and thehead oil control orifice on the cylinder head.
NOTE: Clean the oil control orifice when installing.

2, Tighten the cylinder head bolts in two steps. In thefirst step, tighten all bolts in sequence to about 29N.m (3.0 kgf.m, 22 tbf.ftl. ln the final step, tighten inthe same sequence to 83 N.m (8.S kgf.m,6t lbf.ft).
NOTE:
. Apply clean engine oil to the bolt threads andunder the bolt head.. We recommend using a beam-type torquewrench. When using a preset-type torque wrench,be sure to tighten slowly and not to overtighten.. lf a bolt makes any noise while you are torquing it,loosen the bolt, and retighten it from the 1st step.

NOTE: Use commercially-available computerized four
wheel alignment equipment to measure wheel align-
ment (caster, camber, toe, and turning angle). Follow
the equipment manufacturer's instructions.

Center steering wheel spokes.
Check the toe with the wheels pointed straight

. Example:
After the rear toe inspection, the wheel is 2 mm
(0.08 in) out of the specification.- Move the arm so the adjusfing bolt moves 2 mm
(0.08 in) inward trom the position recorded before the
adjustment.- The distance the adjusting bolt is moved should be
equal to the amount out-of-specification.
