Inspection
• Clean all parts of dirt and debris.
• Inspect air lines, fittings, and valves for leaks, holes,
cracks, and loose connections. Replace parts found
to be unserviceable.
• Check all threaded components for damaged or
stripped threads. Repair light damage with thread
chasers. Replace parts found to be unserviceable.
Installation
Installation is the reverse of the removal procedure.
• Test operation of brake system.
• Avoid personal injury from explosion. Air
system components may contain pressurized
gases. Exposure to excessive heat may
cause components to explode.
• Avoid personal injury from high-pressure
gases or debris. High-pressure release of
gases or debris from a pressurized system
can cause penetrating injuries. Relieve
system pressure from air system before
servicing.
