4) Install rotor plate. Tighten 5 screw securely.
After installing plate, check to be sure that gears turn smoothly
by hand.

.m (1.1 kg-m, 8.0 lb-ft)
5) Apply engine oil to guide seal (3) and install guide seal and guide
(2).
INSTALLATION
1) Install two oil pump pins and oil pump gasket to cylinder block.
Use a new gasket.
2) To prevent oil seal lip from being damaged or upturned when
installing oil pump to crankshaft, fit special tool (Oil seal guide)
to crankshaft, and apply engine oil to special tool.
Special Tool
(A): 09926-18210
3) Install oil pump to cylinder block.
As there are 2 types of oil pump bolts, refer to figure for their cor-
rect use and tighten them to specified torque.

4) Install rubber seal between oil pump and water pump.

6A1-48 ENGINE MECHANICAL (G13B, 1-CAM 16-VALVES ENGINE)

Flatness of gasketed surface:
Using a straightedge and thickness gauge, check surface at a to-
tal of 6 locations. If distortion limit, given below, is exceeded, cor-
rect gasketed surface with a surface plate and abrasive paper of
about #400 (Waterproof silicon carbide abrasive paper): place
paper on and over surface plate, and rub gasketed surface
against paper to grind off high spots. Should this fail to reduce
thickness gauge readings to within limit, replace cylinder head.
Leakage of combustion gases from this gasketed joint is often
due to warped gasketed surface: such leakage results in reduced
power output.
Limit of distortion: 0.05 mm (0.002 in.)

Distortion of manifold seating faces:
Check seating faces of cylinder head for manifolds, using a
straightedge and thickness gauge, in order to determine whether
these faces should be corrected or cylinder head replaced.
Limit of distortion: 0.10 mm (0.004 in.)

Valve Springs

Referring to data given below, check to be sure that each spring
is in sound condition, free of any evidence of breakage or weak-
ening. Remember, weakened valve springs can cause chatter,
not to mention possibility of reducing power output due to gas
leakage caused by decreased seating pressure.

Spring squareness:
Use a square and surface plate to check each spring for square-
ness in terms of clearance between end of valve spring and
square. Valve springs found to exhibit a larger clearance than limit
given below must be replaced.
Valve spring squareness limit: 1.6 mm (0.063 in.)

REMOVAL
1) Remove engine assembly from body as previously outlined.
2) Remove clutch cover, clutch disc and flywheel (drive plate for
A / T).
Special Tool
(A): 09924-17810
3) Remove crankshaft pulley, timing belt and crankshaft timing
pulley.
4) Remove cylinder head assembly.
5) Remove oil pan and oil pump strainer.
6) Remove oil pump (1).
7) Remove oil seal housing.
8) Remove connecting rod bearing caps.
9) Loosen crankshaft bearing cap bolts in such order as indicated
in figure a little at a time and remove bearing caps.
10) Remove crankshaft from cylinder block.

1. Short bolts
2. Long bolts

3) Install crankshaft to cylinder block.
4) Install bearing cap to cylinder block, making sure to point arrow
mark (on each cap) to crankshaft pulley side. Fit them sequen-
tially in ascending order, 1, 2, 3, 4 and 5, starting from pulley side.
After installing bearing cap stiffeners, tighten bearing cap bolts
in such order as shown in figure a little at a time and repeat it till
they are tightened to specified torque.
Tightening Torque

.m (5.4 kg-m, 39.0 lb-ft)
NOTE:
After tightening cap bolts, check to be sure that crankshaft
rotates smoothly when turning it by 8.0 N
.m (0.8 kg-m, 5.8
lb-ft) torque or below.
5) Install new gasket and oil seal housing.
Do not reuse gasket removed in disassembly. Apply engine oil
to oil seal lip before installation. Tighten housing bolts to specifi-
cation.
Tightening Torque
(a): 11 N
.m (1.1 kg-m, 8.0 lb-ft)
NOTE:
As there are 2 types of housing bolts, refer to figure for their
correct use.
After installing oil seal housing, gasket edges might bulge out;
if so, cut them off to make them flush with cylinder block and oil
seal housing.
6) Install oil pump.
Refer to item “Oil pump” for installation of oil pump.
7) Install flywheel (M / T model) or drive plate (A / T model).
Using special tool, lock flywheel or drive plate, and torque its
bolts to specification.
