INTRODUCTION
This section describes general procedures that apply to all parts of the Bridge Adapter Pallet (BAP). To avoid
repetition, these procedures are not described in specific maintenance paragraphs.
GENERAL REMOVAL INSTRUCTIONS
Work Required. Remove only those parts needing repair or replacement. Do not disassemble a component any
further than needed.
Preparation. Before removing any parts of electrical or hydraulic systems, ensure system is not energized or
pressurized. Disconnect batteries before doing any work to electrical system. Ensure parking brake is applied,
wheels are blocked, and all controls are in OFF position before starting any removal procedure.
Removal. Ensure there is enough clearance to remove a part. Disassemble adjacent parts as needed to provide
working clearance.
Lifting. Always use a chain hoist, jack, or other aid when lifting heavy parts. Ensure load limit of lifting devices is
not exceeded by weight being lifted. Position and rig lifting devices before disconnecting any part for removal.
Identification. Tag or mark all similar parts, such as electrical leads, before disconnecting and removing part. This
will make proper assembly easier. Ensure to identify mating ends of electric, hydraulic, and air lines as they are
disconnected.
Position of Valves. Before removing valve handles, mark or diagram their positions when opened and closed. This
will help during assembly.
Electrical Wires and Connectors. Electrical wires and connectors are identified on electrical schematic. Wherever
possible, these wire and connector numbers are also provided in troubleshooting and maintenance tasks.
GENERAL DISASSEMBLY INSTRUCTIONS
Cleanliness. Work area must be kept as clean as possible. This will prevent contamination of internal parts. This is
especially true for valves, cylinders, and other hydraulic or air system parts.
