2.8.14 SERVICE COMPARTMENTS AND ACCESS DOORS
2.8.14.1 INTERIOR
Access for maintenance and replacement of equipment shall be provided by panels and doors that
appear to be an integral part of the interior. Removal of fixtures or equipment unrelated to the repair
task to gain access shall be minimized. Access doors, if hinged, shall be hinged with props, as
necessary, to hold the doors up and out of the mechanic's way with the exception of the destination sign
box door which hinges down and is held by chains in the open position. Panel fasteners shall be
standardized so that only two tools are required to service all special fasteners within the coach. These
fasteners shall be captive in the panel except for the engine compartment access hatches. Access doors
for the door actuator compartments shall be secured with hand screws or latches, and shall be sealed to
prevent entry of mechanism lubricant into the coach interior. All hinges and props must be designed to
preclude accidental closure when the panels are opened.
2.8.14.2 EXTERIOR
Vertically hinged doors shall be used for the engine compartment and for all auxiliary equipment
compartments including doors for checking the quantity and adding to the engine coolant, engine
lubricant, transmission fluid and the windshield washer reservoir. The upper engine radiator/C.A.C.
compartment door may be horizontally hinged. Access to these compartments shall be from outside the
coach. Access openings shall be sized for easy performance of tasks within the compartment including
tool operating space. Access doors shall be of rugged construction and shall be capable of withstanding
severe abuse throughout the life of the coach. They shall close flush with the body surface. All doors
shall be hinged at the top or on the forward edge and shall be prevented from coming loose or opening
during transit service or in coach washing operations. Doors with top hinges shall have safety props
stored behind the door or on the door frame. All access doors (except vertically hinged access doors)
shall be sufficiently retained in the open position by props or counterbalancing. Gas springs shall only
be permitted on the rear upper engine cooling door. Springs and hinges shall be corrosion-resistant and
shall last throughout the service life of the coach. Latch handles shall be sized to provide an adequate
grip for opening. Large access doors shall hinge up and out of the way or fold flat against the coach
body and shall be easily operable by one person. These doors, when opened, shall not restrict access
for servicing other components or systems. Retention devices utilized to hold the engine compartment
access doors in the open position shall be heavy duty and designed to last the service life of the coach.
No locks shall be supplied on the battery door or the master switch access door.
