b. Install connecting rodcaps.
Tighten connecting rodcap nuts tothe specified torque.

Tightening procedure:
1) Tighten nutsto14 to16 N'm (1.4to1.6 kg-m, 10to

12 ft-Ib).

2) Turn nuts60to65 degrees clockwise with
angle wrench.
If
angle wrench isnot available,
tighten nutsto38 to44 N'm (3.9to4.5 kg-m, 28

to 33 ft-Ib).

6. Measure connecting rodside clearance.

Connecting rodside clearance:
Standard 0.20 -0.35 mm(0.0079 -0.0138 in)
Limit 0.50 mm(0.0197 in)

If
beyond thelimit, replace connecting rodand/or crank-
shaft.
7. Install rearoilseal retainer.
a. Before installing rearoilseal retainer, removealltraces of
liquid gasket frommating surface usingascraper.
• Also remove tracesofliquid gasket frommating surface of
cylinder block.
b. Apply acontinuous beadofliquid gasket tomating surface
of rear oilseal retainer.
• Use Genuine LiquidGasket orequivalent.

1. Drain oil.
2. Remove oilpan using toolasillustrated.
1) Insert Toolbetween oilpan andcylinder block.

• Do not drive sealcutter intooilpump orrear oilseal
retainer portion,oraluminum matingsurfaces willbedam-
aged.
• Do not insert screwdriver, oroil pan flange willbe
deformed.

2) Slide Toolbytapping itwith ahammer, andremove oilpan.

Installation
1. Before installing oilpan, remove alltraces ofliquid gasket
from mating surface usingascraper.
• Also remove tracesofliquid gasket frommating surface of
cylinder block.
• Besure liquid gasket is3.5 to4.5 mm (0.138 to0.177 in)
wide.

Use Genuine LiquidGasket orequivalent.
