011 Drain Hose
An oil sump drain hose is installed on the engine wtth the discharge end secured by a
bracket at the front of the engine. Oil may be drained from this hose by removing the
cap and the discharge end of the hose from the support bracket and lowering the hose
into a container. The hose cap fttting is 1/4 inch NPT (National Pipe Tap) and can be ex-
tended. or have a pup added, for easier removal of the old oil,
if
desired.
Connecting Pressure Sensing Devices to 011 Gallerlos
Oil pressure sensing devices, such as senders and swttches, must not be connected to an
engine's oil gallery wtth the use of extended nipples or tees. The reason is simply that
continued engine vibration causes fatigue of the ftttings used to make such a connection.
If these fittings fail during engine operation, lubricating oil will be lost and internal engine
damage will resutt.
When additional sensing devices such as swttched or sensors need to be installed that
function on engine oil pressure, these devices mug be bulkhead-mounted and connected to
the oil gallery using an appropriated grade of lubricating oil hose. Any fittings used to con-
nect the hose to the gallery mug be of steel or malleable iron composttion. Brass must
not be used for this application.
Electrical System
The electrical system should be checked to make sure all wiring harnesses are properly tied
down with clamps or plastic ties and that all wiring harnesses are spaced at intervals close
enough to prevent chafing from vibration. Check to make sure all engine harness connections
are tight and that they are made to the appropriate terminals.
DC Electrical Connections
A common ground for the negative (-) DC terminal connection is found at the bellhousing
of the generator, next to the starter, in the form of a threaded grounding stud. The bat-
tery ground should be connected at this stud.
Connect the battery's positive (+) connection to the starter solenoid tagged for this connec·
tion.

fAOTIONI
To avoid an overcharging condition, and a possible equipment failure
do not disconnect the DC battery source while the engine is running.
