Seacock Maintenance
With proper maintenance, your solid bronze Spartan
Seacock, will provide years of adequate service.
Winterizing
Make sure if the boat is hauled during a freezing
season that the water is properly drained from the
seacock plug. This can be accomplished by leaving
the seacock open during hauling out. If the boat is kept
in the water during a freezing season there are winter
drain fasteners (Fig. A) located on the sides of the
valve to allow water to exit when the seacock is closed.
Caution: Water left in the seacock to freeze will distort
the metal and potentially fracture the casting.
Lubrication
The Spartan Seacock is designed to be disassembled
for greasing and fine tuning. (Fig. B)
1. Holding the handle
15
unscrew the jam nut
10
and
flange nut
11
off the plug threads
14
. The position
washer
12
can then be lifted off. Lightly tap
theplug14 out of the body
13
with a soft hammer or
wood piece.
2. Use a grease cutting solvent to clean the valve
plug
14
surface and body
13
plug housing. Note
any surface gouges. These can be smoothed with
fine emery cloth. Lapping compound is available
from Spartan Marine Products, Inc. to aid with
severe surface problems.
3. Generously apply a new skin of water pump
grease on the plug
14
surface. Insert the plug in the
body
13
and locate the position washer
12
properly
on the end of the plug
14
. (The position washer
should turn with the direction of the plug.) Screw
the flange nut
11
onto the plug
14
thread and hand
tighten. Follow that with the jam nut
10
.
4. Tensioning the plug
14
is done by holding the
handle
15
and tightening the flange nut
11
. The
tension on the plug should be adequate to hold it
in place when subjected to engine or other normal
boat use vibration. Do not make it too tight to
operate. The flange nut
11
is locked in place by
seating the jam, nut
10
securely next to it. .
ANNUAL MAINTENANCE IS SUFFICIENT TO
SUSTAIN PROPER SEACOCK OPERATION.
