This Part of Chapter 2 is devoted to in-vehicle repair procedures for
the 2.6L timing chain engines, All information concerning engine removaf
and installation and engine block and cylinder head overhaul can be found
in Part D of this Chapter.
The following repair procedures are based on the assumption that the
engine is installed in the vehicle. If the engine has been removed from the
vehicle and mounted on a stand, many of the steps outlined in this Part
of Chapter 2 will not apply.
The Specifications included in this Part of Chapter 2 apply only to the
procedurescontained in this Par-t. PartD of Chapter2contains the Specifi-
cations necessary for cylinder head and engine block rebuilding.
The 2.6L engine is an inline vertical four, with a chain-driven overhead
camshaft and a silent shaft counterbalancing system which cancels the
engine’s power pulses and produces relatively vibration-free operation.
The crankshaft rides in five renewable insert-type main bearings, with the
center bearing (the thrust bearing) assigned the additional task of control-
ling crankshaft endplay.
The pistons have two compression rings and one oil control ring. The
semi-floating piston pins are press fitted into the small end of the conned-
ing rod. The connecting rod big ends are also equipped with renewable
insert-type plain bearings.
The engine is liquid-cooled, utilizing a centrifugal impeller-type pump,
driven by a belt from the camshaft, to circulate coolant around the cy%i-
ders and combustion chambers and through the,intake manifold.
Lubrication is handled by a gear-type oil pump mounted on the front
of the engine under the timing chain cover. It is driven by the silent shaft-
chain. The oil is filtered continuously by a cartridge-type filter mounted on
the radiator side of the engine.
