B-l. GENERAL
All
'Jeep' Universal vehicles require periodic
lubri­

cation and other maintenance services for normal
vehicle
usage
and application to promote satis­ factory operation and prevent
excessive
wear. Un­
der severe operating or atmospheric conditions
these
services should be performed more
often
than
under normal conditions. It should also be remem­
bered that common short trips and
stop-and-go
driving
are more severe on lubrication
points
than

driving on highways, and even more
intensified in extreme cold or hot weather; there­ fore, vehicles driven under
these
conditions must
be lubricated and serviced more
often
than nor­ mally operated vehicles. The specifications of

in the block and cylinder head.

The
water cooled system is pressurized to provide efficient
engine
cooling. It consists of a centrifugal-
type water pump, mounted on the timing chain cover, and is driven by the
engine
fan pulley. The
pump provides coolant flow equally to both
cylin­
der banks under control of a thermostat. Coolant
flow is around the cylinders and through the
cylinder
head to dispel the heat of combustion in
the engine.

Dl-3.
Engine Mounts

The
engine-transmission unit is mounted to the chassis at three points by rubber pads. The two
front mounts are bolted to the
engine
cylinder
block and the frame members. These mounts sup­ port most of the
engine
weight, and absorb
vibra­

tion which would otherwise be caused by changes
in
engine
output torque. The single
rear
mount is
placed
between
the transmission and the trans­ mission support. It supports part of the engine'

and
transmission weight, and locates the
rear
of
the
engine
with respect to the centerline of the
vehicle.

Dl-5.
ENGINE DISASSEMBLY

Engine
disassembly is presented in the sequence to be followed when the
engine
is to be completely
overhauled after removal from the vehicle. Some of the operations of the procedure are also appli­cable separately with the
engine
in the vehicle,
provided that wherever necessary the part of the
engine
to be worked on is first made accessible by removal of
engine
accessories or other parts.

When
the disassembly operations are performed
with
the
engine
out of the vehicle, it is assumed,
in
this procedure, that all of the accessories have
been removed
prior
to starting the disassembly and
the oil has been drained.
