and hoist to lifting
brackets at exhaust
manifolds.
Remove
engine from work
stand.
2.
Lower the engine carefully into
the engine compartment. Make sure the
exhaust manifolds are properly aligned
with the muffler inlet pipes.
On a vehicle with an automatic
transmission, start the converter pilot into
the
crankshaft.
On a vehicle with a manual-shift
transmission, start the transmission main
drive gear into the clutch disc. It may be
necessary to adjust the position of the
transmission in relation to the engine if
the input shaft will not enter the clutch
disc.
If
the engine hangs up after the shaft
enters,
tum
the
crankshaft
slowly
(transmission in gear) until the shaft
splines mesh with the clutch disc splines.
3.
Install
the
bell
housing
or
converter housing upper bolts, making
sure that the dowels in the cylinder block
engage the flywheel
housing.
Remove the
jack from under the transmission.
4.
Remove the lifting
sling.
5. On
automatic
transmission
equipped vehicles, position the downshift
rod on the transmission and engine.
6. Raise the vehicle and secure with
safety
stands.
7.
On a vehicle with an automatic
transmission,
position the transmission
linkage bracket and install the remaining
converter housing bolts. Install the adapter
plate-to-converter housing
bolt.
Install the
converter-to-flywheel nuts and install the
inspection cover. Connect the downshift
rod on the transmission.
On
a
vehicle
with
a
manual
transmission,
install the lower bell housing
bolts and replace the clutch slave cylinder.
8. Install the starter and connect the
cable.
9. Connect the muffler inlet pipes at
the exhaust manifolds.
10.
Install the engine front support
through bolts and install the starter cable
clamp at the right front engine support.
11. Lower the vehicle.
12. Install the ground wire at the
right cylinder head. Install the engine wire
loom and connect it to the ignition coil,
water temperature sending unit and oil
pressure sending
unit.
13. Install the accelerator linkage and
connect the downshift rod, if so equipped.
14. Connect the vacuum lines at the
rear of the intake
manifold.
Connect the
fuel tank line at the fuel
pump.

MAJOR REPAIR OPERATIONS
When installing nuts or bolts that
must be torqued (to
specifications),
oil
the threads with light weight engine oil.
Do not oil threads that require oil-resistant
or water-resistant sealer.
To perform the operations in this
section, it will be necessary to remove the
engine from the vehicle and install it on a
work stand as previously
described.
Refer to page 8-15 for cleaning and
inspection procedures.

4. Remove
the
timing
pointer.
Remove the water pump and cylinder
front cover as an assembly. Discard the
gasket and remove the crankshaft front oil
