SECTION 5
– Installation
NOTICE:
REFER TO THE SHIRE AND YANMAR MANUALS PRIOR TO INSTALLING THE
ENGINE.
1. Ventilation
•
All internal combustion engines radiate heat and require cool, clean air to aid complete
combustion.
•
Please ensure that adequate engine room ventilation is provided, by fitting at least two
vents of an aperture of not less than 15,000mm
2
each (24in
2
).
An allowance must be made for any grills, louvres or bends placed in the
airflows and generally an increase of 25% in area is sufficient to overcome any
restriction problems.
2. Engine Beds
•
These should be a minimum of 10mm thick, extended rearward and be welded to the
hull and forward to the bulkhead. Webs or gussets must be welded in place midway
to prevent flexing.
3. Engine Cooling Water Inlet and Outlet Hose Connections
•
The connections are on the right hand (starboard) side of the engine.
•
Use 100mm ID suitable machine flexible exhaust hose. Do not step down to a smaller
size.
•
Use a good quality hose that cannot collapse or kink and is capable of working at
temperatures in excess of 100°C.
4. Pressurised Water Header Tank
WARNING:
SCALD HAZARD!
NEVER REMOVE THE HEADER TANK CAP IF THE ENGINE IS
HOT. STEAM AND HOT COOLANT MAY SPURT OUT AND CAUSE INJURY. TIGHTEN
THE HEADER TANK CAP SECURELY AFTER BEING REMOVED. STEAM CAN
SPURT OUT DURING ENGINE OPERATION IF THE CAP IS LOOSE.
