3.1.2.2 SERVICE Page 38 ATTACHMENT 2 The powerplant shall be arranged so that accessibility for all routine maintenance is assured. No special tools, other than dollies and hoists shall be required to remove the powerplant. The powerplant shall be mounted on a cradle which can be slid into and out of the coach. Two mechanics shall be able to remove, replace and prepare the engine and transmission assembly for service in less than 25 total combined man-hours. The muffler, exhaust system, air cleaner, air compressor, starter, turbocharger, alternator, radiator, including charge air circuit, all accessories, and any other components requiring service or replacement shall be installed in or above the engine compartment. The turbocharger, alternator, air compressor, and starter shall be replaceable without dismounting or removing other coach parts and without gaining access through the coach interior. The cooling system filler caps shall be hinged to the filler neck and be held closed with spring pressure or positive locks. The transmission filler tube shall employ a combination dipstick and cap and shall be the minimum length permissible to discourage daily fluid checking. All fluid fill locations shall be properly labeled to help ensure correct fluid is added and all shall be easily accessible with standard funnels, pour spouts, and automatic dispensing equipment. All lubricant sumps shall be fitted with magnetic-type, external, hex head, drain plugs of a standard size except for the transmission which uses a recessed square socket type plug. The powerplant shall be equipped with provisions for displaying engine and transmission data. The engine and transmission shall be equipped with sufficient heavy-duty fluid filters for efficient operation and to protect the engine and transmission between scheduled filter changes. To the extent practicable, the filters shall be of the spin-on, disposable type with the exception of the engine which shall have a fuel pro 382 without heater in lieu of dual fuel filters. All filters shall be easily accessible and the filter bases shall be plumbed in a manner so as to assure correct reinstallation. Flexible lines shall be teflon hoses with braided stainless steel jackets except in applications where premium hoses are required and shall have standard SAE or JIC brass or steel, reusable, swivel end fittings. Hoses shall be individually supported and shall not touch one another or any part of the coach. 3.1.2.3 AIR CLEANER The air cleaner shall be a dry type, be horizontally mounted, and be equipped with a pre cleaner system. Airflow through the filter element shall be from the outside in. To service the filter shall take less than 5 minutes, disconnecting an engine air intake duct, air compressor intake duct, or filter housing shall not be necessary. The access cover of the air filter assembly shall be retained to the filter housing with a single wing nut. A Filter Minder air filter restriction indicator, part #1875-325, manufactured by Engineered Products Co. shall be provided and calibrated to 25 inches of water/vacuum. 3.1.2.4 ACCESSORIES These accessories shall be unit mounted for quick removal and repair. These accessories shall be driven at speeds sufficient to assure adequate system performance during extended periods of operation. The
Page 39 ATTACHMENT 2 power steering pump and air compressor shall be flange mounted and gear driven from engine. The power steering reservoir shall be remotely mounted to the bus chassis and shall not be mounted on the drivetrain. The alternator shall be a Neihoff air cooled rated no less 450 amp or approved equal. Only the 24 volt alternator, A/C compressor and cooling system fans may employ belt drives. Tension on all belt driven components shall be maintained by manually adjusted turnbuckles or idlers. 3.1.2.5 HYDRAULIC DRIVE Hydraulic system service tasks shall be minimized and scheduled not more frequently than scheduled tasks for other major coach systems. All elements of the hydraulic system shall be easily accessible for service or unit replacement. All lines shall be compatible with the hydraulic fluid and maximum pressures of the system. Flexible lines shall be minimized in quantity and length. Lines of the same size and with the same fittings as those on other piping systems of the coach, but not interchangeable, shall be tagged or marked for use on the hydraulic system only. Hydraulic lines shall be individually and rigidly supported to prevent chafing damage, fatigue failures, and tension strain on the lines and fitting. Hydraulically driven radiator and charge air cooler fan drive systems are not acceptable. The hydraulic system shall be configured and/or shielded so that failure of any flexible line shall not allow hydraulic fluid to spray or drain onto any component operable above the auto-ignition temperature of the fluid. 3.1.3 POWERPLANT 3.1.3.1 ENGINE Engine to be certified at time of manufacture to meet EPA Clear Air Act. 3.1.3.2 COOLING SYSTEM The cooling system shall be sized to maintain fluids at safe, continuous operating temperatures during the most severe operations possible with the coach loaded to GVWR and with ambient temperatures up to 110 deg. F. Sufficient reserve capacity shall be provided by the cooling system to provide efficient cooling for the coolant and engine charge air with 25% of the system in a degraded condition. Radiator shall be Modine or approved equal . Radiator, complete with charge air cooling circuit shall be provided, mounted above the engine compartment. The charge air cooler and the radiator shall be mounted at least 60 inches above the road surface. The physical size and heat rejection capacity of the radiator along with the charge air cooling capacity shall be tested and approved by the engine manufacturer for this application. The radiator system shall be easily serviced through a top hinged access door. The radiator and charge air cooler shall not be stacked in front of one another. Door shall include gas-filled cylinders and a manual prop to hold the door in the upright/open position. The charge air/cooling system radiator shall be Modine or approved equal and shall be of durable corrosion-resistant construction with welded-on tanks. Radiator plumbing shall be stainless steel, copper, aluminized steel or brass tubing and if practicable, rubber hoses shall be eliminated. Necessary hoses shall be premium, silicone rubber type that are impervious to all coach fluids. All CAC hoses and coolant hoses shall be secured with Oetiker hose clamps. Fan speed shall be regulated to minimize fan noise. No heat producing components or climate control system components shall be mounted between
