REMOVAL
1. Remove the following parts.
lUndercover
lDrive belt; Refer toEM-12, "DRIVE BELTS".
lCrankshaft pulley; Refer toEM-79, "PRIMARY TIMING CHAIN".
2. Remove front oil seal with a suitable tool.
CAUTION:
Be careful not to damage oil pump housing and crankshaft.
INSTALLATION
1. Apply new engine oil to new front oil seal joint surface and seal lip.
2. Install front oil seal so that each seal lip is oriented as shown in
the figure.
lUsing the suitable drift [60 mm (2.36 in) dia.] (A), press fit the
oil seal (2) so that the dimension is as specified in the figure.
CAUTION:
Do not touch lips of oil seal. Make sure seal surfaces are
free of foreign materials.

CAUTION:
lAfter removing timing chain, do not turn crankshaft and camshaft separately, or valves will strike
piston heads.
lWhen installing camshafts, chain tensioners, oil seals, or other sliding parts, lubricate contacting
surfaces with new engine oil.
REMOVAL
lFor preparative work for removing/installing secondary timing chain to remove/install fuel pump, refer to
EM-49, "
FUEL PUMP".
lTo prepare for removing/installing secondary timing chain to remove/install camshaft, refer toEM-59,
"Removal and Installation".
1. Remove radiator shroud (upper and lower) and cooling fan (crankshaft driven type). Refer toCO-11,
"RADIATOR"andCO-19, "COOLING FAN".
2. Remove EGR cooler (A/T models) and related water hoses, or EGR tube (M/T models).
CAUTION:
lPerform this step when engine is cold.
lDo not spill engine coolant on drive belts.
3. Remove front chain case.
