Exhaust manifolds are subject to such extreme
variations in temperature that the metal expands
and contracts to a considerable degree. T h i s
condition makes the manifolds " C r e e p " on the
gaskets—a condition which has no undesirable
effect unless the bolts are drawn up too tight.
M a n i f o l d bolts need not be extremely tight-
T h e y should be tightened while the engine is
running and should be drawn up just enough to
stop a l l exhaust leaks. If the bolts are tightened
too securely, the "creeping" of the manifold may
rip the gasket and permit it to burn out.
The possibility of intake and exhaust gaskets
blowing out can be greatly reduced by coating
them with gasket paste (See Note 15) before
installing. T h i s treatment makes it easier for
the manifold to expand and contract without
pulling or wrinkling the gasket.
42. S e r v i c i n g F u e l a n d V a c u u m P u m p s
The service operations that can be performed on
the fuel and vacuum pumps without special tools
are the cleaning of the filter and replacement of
the filter parts, the vapor dome, and the inlet and
outlet valves. Under no circumstances should
either of the pump housings be disassembled unless
the necessary special tools for reassembly are
available.
Service on the fuel pumps or v a c u u m pumps,
whether of single unit or separate type, can be
obtained from A . C . service stations, where special
tools and spare parts are at hand. Distributors
who wish to make repairs in their own stations
can purchase the necessary tools at an A . C .
service station. Others may keep a spare pump
of each type in stock for exchange to assure
prompt service.
43. A d j u s t i n g E n g i n e S u p p o r t s
S e r i e s 37-50, 60, 65, 70 a n d 75 — T h e front
engine supports of 37-series V - 8 engines do not
require any adjustment; simply draw the support
bolts up tight enough to hold the engine in posi-
tion on the rubber cushion.
T h e rear engine support should be tightened
finger tight,, and then drawn up % • of a t u r n
further with a wrench and locked in position.
See Plate 45, F i g . 66.
S e r i e s 37-85—On the 37-series V-12 engine w i t h
' a five point mounting, the front engine supports
should be tightened first. Next, the rear engine
support under the transmission extension should
be tightened finger tight, and then, drawn up Yi
turn further w i t h a wrench and locked in position.
A n d then the intermediate engine supports
should be tightened as a final step. See Plate 45,
F i g . -67:
S e r i e s 37-90—On the 37-series V - 1 6 engines,
the procedure for adjusting the engine supports,
as shown in Plate 45, F i g . 68, is as follows:
1. Place engine weight on front and rear
supports.
2. Tighten nuts on front support through
bolts until lower retainer contacts w i t h rubber,
then draw up nut turn further and lock in
•position.
3. L e a v i n g support loose on frame cross
member, tighten through bolt i n intermediate
engine support, just enough to take up clearance
between rubbers and retainers,
4. Install shims under rear engine support to
raise the rear end of the engine until, w i t h the
weight of the engine on the rear support, the
bolts holding the intermediate support bracket to
the frame sidebar can be installed without any
binding whatsoever.
Note: Insert shims between sidebar and sup-
port casting, if needed to prevent cocking
of the through bolts.
5. Tighten the bolts holding the intermediate
support bracket to the frame securely w i t h the
engine raised as explained.
6. Remove the shims from under the rear
engine support and tighten support to cross
member.
7. T i g h t e n nuts on through bolt in intermediate
engine supports to take up all clearance of parts,
and then draw up 2 turns further and lock in
position.
