EXHAUST SYSTEM
(3) Disconnect the exhaust pipe at the exhaust
manifold and remove the exhaust pipe. On models
using gaskets at the exhaust pipe flanges, discard the
gaskets and carefully clean the manifold flanges of
any gasket particles.
(4)
Remove the muffler and the extension pipe as-
sembly.
(5)
Raise the rear end of vehicle to relieve the body
weight from the
rear
springs and remove the tail
pipe.
Installation
(1) Assemble the exhaust system loosely to permit
the proper alignment (Figs.
1,
2,
3,
4,
5,
6
and
7).
(2) Connect the exhaust pipe to exhaust manifolds,
using new gaskets, where required. Tighten the ex-
haust pipe attaching bolt nuts to
35
foot-pounds. On
systems using the ball joint seating connection at the
exhaust manifold, do not tighten the attaching bolt
nuts at this time.
(3) Adjust the supports and hangers to provide
proper underbody clearance and clearance with ad-
jacent parts. Do not fully tighten attaching bolts and
screws at this time.
(4)
Tighten all slip joint clamp bolt nuts to 100
inch-pounds, working from
rear
to front.
(5)
Tighten all support and hanger attaching bolts
and nuts to
95
inch-pounds, at same time maintaining
proper clearance with adjacent parts.
(6)
Tighten the ball joint connection bolt nuts
to
35
foot-pounds. When tightening bolts, alternate
tightening between the bolts to insure parallelism of
flanges.
INTAKE AND EXHAUST MANIFOLD
ASSEMBLY (6Cyl. Engines)
Removal
(1)
Remove the carburetor air cleaner.
If
the en-
gine is equipped with the closed type
oil breather cap,
disconnect the hose at the air cleaner intake tube.
(2)
Disconnect the vacuum control tube at the car-
buretor and distributor. Disconnect the fuel line, the
crankcase ventilating valve hose, the automatic choke
rod and throttle at the carburetor and remove the
carburetor.
(3) Disconnect the exhaust' pipe at the exhaust
manifold.
(4)
Remove the nuts and washers attaching the
manifold assembly to the cylinder head and remove
the manifold (Fig.
8).
Remove the three screws secur-
ing the intake manifold to the exhaust manifold and
separate the manifolds.
(5)
Discard the gasket and clean all gasket surfaces
on the manifolds. Wash the manifolds in solvent and
dry with compressed air.
(6) Test the mating surfaces of manifolds for par-
allelism with a straightedge. Surfaces should be flat
within
.008
inch.
