Check clearance by using gaging plastic.
The procedure is as follows.
1) Clean housing and camshaft journals.
2) Install camshaft to cylinder head.
3) Place a piece of gaging plastic the full width of journal of cam-
shaft (parallel to camshaft).
4) Install camshaft housing referring to “INSTALLATION” of the fol-
lowing page.
5) Tighten camshaft housing bolts in such order as indicated in fig-
ure a little at a time till they are tightened to specified torque.

(a): 11 N
.m (1.1kg-m, 8.0 lb-ft)
NOTE:
Do not rotate camshaft while gaging plastic is installed.
6) Remove housing and using scale (2) on gaging plastic (1) enve-
lope, measure gaging plastic width at its widest point.

If measured camshaft journal clearance exceeds limit, measure
journal (housing) bore and outside diameter of camshaft journal.
Replace camshaft or cylinder head assembly whichever the dif-
ference from specification is greater.

REMOVAL
1) Remove cylinder head from cylinder block as previously out-
lined.
2) Drain engine oil.
3) Remove oil pan and oil pump strainer as previously outlined.
4) Mark cylinder number on all pistons, connecting rods and rod
bearing caps, using silver pencil or quick drying paint.
5) Remove rod bearing caps.
6) Install guide hose (1) over threads of rod bolts. This is to prevent
damage to bearing journal and rod bolt threads when removing
connecting rod.

6A1-62 ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE)
INSTALLATION OR CONNECTION
1) Apply engine oil to pistons, rings, cylinder walls, connecting rod
bearings and crankpins.
NOTE:
Do not apply oil between connecting rod and bearing or be-
tween bearing cap and bearing.
2) Install guide hoses over connecting rod bolts.
These guide hoses protect crankpin and threads of rod bolt from
damage during installation of connecting rod and piston assem-
bly.
3) When installing piston and connecting rod assembly into cylin-
der bore, point arrow mark on piston head to crankshaft pulley
side.
4) Install piston and connecting rod assembly into cylinder bore.
Use special tool (Piston ring compressor) to compress rings.
Guide connecting rod into place on crankshaft.
Using a hammer handle, tap piston head to install piston into
bore. Hold ring compressor firmly against cylinder block until all
piston rings have entered cylinder bore.
