INSTALLATION
7
FOREWORD
Since the boats in which these engines are used are many and varied,
details of engine installation are equally so. It is not the purpose of
this section to advise boatyards and engine installers on the generally
well understood and well developed procedures for installation of en-
gines. However, the following outline of general procedure is included
because it is valuable in explaining the functions of each component,
the reasons why, the precautions to be watched and the relationship of
the installation to the operation of the engine. There are details of
the installation which should have a periodic check and of which the
operator should have a thorough understanding to insure good operating
conditions for the engine and correct procedure for its servicing.
INSPECTION OF EQUIPMENT
The engine is shipped from the factory
mounted securely and properly crated. Ac-
cessory equipment is shipped in a separate
small box, usually packed with the engine
crate.
Before accepting shipment from the
transportation company, the crate should
be opened and an inspection made for con-
cealed damage. If either visible or con-
cealed damage is noted, you should require
the delivering agent to sign "Received in
damaged condition". Also check contents
of the shipment against the packing list
and make sure note is made of any discrep-
ancies. This is your protection against
loss or damage. Claims for loss or damage
must be made to the carrier, not to J. H.
Westerbeke Corporation.
RIGGING AND LIFTING
The engine is fitted with lifting rings.
Rope or chain slings should be at-
tached to the rings and the engine lifted
by means of tackle attached to this sling.
The lifting rings have been designed to
carry the full weight of the engine,
therefore auxiliary slings are not re-
quired or desired.
CAUTION: Slings must not be so short as
to place the engine lifting eyes in sig-
nificant sheer stress. Strain on the
engine lifting eyes must not be in excess
of
100
from the vertical. A spacer bar
must be placed between the two lifting
eyes, if supported by valve cover studs.
The general rule in moving engines is
to see that all equipment used is amply
strong and firmly fixed in place. Move the
engine a little at a time and see that it
is firmly supported. Eliminate possibil-
ity of accidents by avoiding haste. Do
not lift from the propeller coupling, or
pry against this with crowbar, as you may
distort the coupling.
In some cases it may be necessary to
lift the engine in other than the regular
horizontal position. It may be that the
engine must be lowered endwise through a
small hatchway which cannot be made larger.
If the opening is extremely restricted it
is possible to reduce, to some extent, the
outside clearances such as generator,
cooling piping, water tank, filters,
mounting lugs, etc. This accessory equip-
ment should be removed by a competent
mechanic and special care should be taken
to avoid damage to any exposed parts and
to avoid dirt entering openings. The parts
which have been removed should be returned
to position as soon as the restriction has
been passed.
In case it is necessary to hoist the
engine either front end upwards or reverse
gear end upwards, the attachment of slings
must be done very carefully to avoid the
possibility of damage to the parts on
which the weight may bear. It is best if
special rigging work be done by someone
experienced and competent in the handling
of heavy machinery.
ENGINE BOLTS
It is recommended that bronze hanger
bolts of appropriate size be used through
the engine flexible mounts. Lag screws
are less preferred because their hold on
the wood is weakened every time they are
moved, whereas the lag bolt stays in pos-
ition and the nut on top is used to tight-
en the engine down or is removed to permit
the engine to be lifted. The bolt itself
stays in
pos~tion
at all times, as a stud,
and the bond between the bolt and the wood
is not weakened by its removal.
