L4-134 ENGINE
Detailed specifications for the L4-134 engine are
given at the end of this section. Torque specifica-
tions are at the end of this manual in Section U.
When adjustments are necessary, refer to these
specifications so that factory clearances are main-
tained.
D-3. Engin~ Mountings
The front of the engine is supported by two rubber
insulator mountings attached to the frame side
rail brackets. The rear of the engine-transmission
assembly is supported by a rubber insulator
mounting under the rear of the transmission on
the frame center cross member. This cross member
is bolted to the frame side rails so that it can be
dropped when removing the transmission or engine-
transmission assembly. The rubber insulators allow
free side and vertical oscillation to effectively
neutralize engine vibration at the source.
The rubber insulator mountings should be inspected
for separation and deterioration by jacking the
power plant away from the frame, near the sup-
ports. Vibration cannot be effectively absorbed by

separated or worn insulators. They should be re-
placed if faulty.
D-4. Engine Ground Strap
To be sure of an effective ground for the electrical
circuits, a ground strap bridges the right front (on
some models, left front) engine support to the
chassis. The connections of this strap must be kept
clean and tight for proper operation of lights,
generator, regulator, etc.
D-5. ENGINE REMOVAL
Should the engine require overhauling, it is neces-
sary to remove it from the vehicle. This may be
accomplished as follows:
a. Drain the cooling system by opening the drain
cocks at the bottom of the radiator and lower right
side of the cylinder block.
b. Disconnect the battery at the positive terminal
to avoid the possibility of a short circuit.
c. Remove both the upper and lower radiator
hoses, and the heater hoses if so equipped.
