INSTALLATION
NOTE:

All parts to be installed must be perfectly clean.

Be sure to oil crankshaft journals, journal bearings, thrust
bearings, crankpins, connecting rod bearings, pistons, pis-
ton rings and cylinder bores.

Journal bearings, bearing caps, connecting rods, rod bear-
ings, rod bearing caps, pistons and piston rings are in com-
bination sets. Do not disturb combination and try to see that
each part goes back to where it came from, when installing.
1) Fit main bearings to cylinder block (1).
Among two halves of main bearing, one halt has oil groove (3).
Install this half with oil groove to cylinder block, and another half
without oil groove to bearing cap.
Make sure that two halves are painted in the same color.
2) Fit thrust bearings (1) to cylinder block between No.2 and No.3
cylinders. Face oil groove (2) sides to crank webs.
3) Put crankshaft on cylinder block.
4) Fit bearing caps sequentially in ascending order, 1, 2, 3 and 4,
starting from pulley side. Be sure to point arrow mark (2) (on
each cap) to crankshaft pulley side (1).
Gradual and uniform tightening is important for bearing cap
bolts. Make sure that four caps become tight equally and pro-
gressively till specified torque is attained.
Tightening Torque
(a): 53 N
.m (5.3 kg-m, 38.5 lb-ft)
NOTE:
After tightening cap bolts, check to be sure that crankshaft
rotates smoothly when turned by hand.

5) Install oil seal housing and its gasket.
Install new gasket. Do not reuse gasket removed in disassem-
bly. Oil lip portion of oil seal before installing. Tighten housing
bolts to specification.
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 and torque its bolts (1) to spec-
ification.

(c): 78 N
.m (7.8 kg-m, 56.5 lb-ft)
8) Install pistons and connecting rods as previously outlined.
9) Install oil pump strainer and oil pan.
10) Install cylinder head assembly to cylinder block (1).
Before installing cylinder head assembly to cylinder block,
install check valve (2) into oil gallery in cylinder block, directing
slit of valve toward top of cylinder block.
NOTE:
Tighten cylinder head bolts to specified torque as pre-
viously outlined.
Whenever installing cylinder head to new cylinder block,
use following procedure to tighten cylinder head bolts.

Tighten cylinder head bolts to specified torque as pre-
viously outlined and loosen them once till tightening
torque becomes “zero”. And then torque them to specifi-
cation again.
11) Install crankshaft timing belt pulley, timing belt, crankshaft
pulley, water pump pulley, etc., as previously outlined.
12) Install clutch to flywheel (M / T model).
For clutch installation, refer to Section 7C.
13) Install engine with transmission to body as previously outlined.

WARNING:
For vehicles equipped with Supplement Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under “Gener-
al Description” in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either or these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).
