This document, titled "Ducting & Exhaust," is a section of the Argo Service Manual, specifically focusing on the maintenance, removal, and installation procedures for the exhaust and intake systems of various Argo all-terrain vehicles. It provides detailed, step-by-step instructions accompanied by photographic illustrations to guide qualified service personnel through these operations.

Function Description:

The manual details the procedures for servicing the exhaust and intake ducting systems. The exhaust system is crucial for directing hot exhaust gases away from the engine and vehicle occupants, reducing noise, and often includes a spark arrestor to prevent ignition of flammable materials in the environment. The intake ducting system is responsible for channeling clean air to the engine's air intake, protecting it from debris and water, and often contributing to engine cooling by directing airflow. Proper functioning of both systems is vital for engine performance, safety, and environmental compliance.

Important Technical Specifications (Implied and Explicit):

Vehicle Models Covered: The manual explicitly covers a range of Argo models, including:
- Conquest (various serial number ranges, e.g., prior to C19672, from C19672, from C19686, all 6x6 Conquests, all 35th Anniversary Models, prior to CB17117, from C12747 for spark arrestors).
- Response.
- Vanguard2.
- Vanguard (various serial number ranges, e.g., prior to R19647, S13434, N13436, from R19647, S13434, N13436, prior to S8131, from S6999, SN8138, RB12075, from S13434, N13436, R19647).
- Bigfoot (various serial number ranges, e.g., from BF13028 for spark arrestors).
Muffler Assembly Components: The muffler assembly typically includes a heat shield, manifold cover, lower shroud, muffler, exhaust manifold, tailpipe, and spark arrestor. Hardware includes bolts, flatwashers, compression springs, and locking style nuts.
Intake Ducting Components: Intake ducts can be made of sheet metal (older Conquest models) or moulded plastic (newer Conquest models). They are secured by fasteners, spacers, and sometimes connected to the lower body with a spring and molly hook (older 6x6 Vanguards). Fuel lines are often clipped to the intake duct.
Exhaust Ducting Components: Exhaust ducting is secured by fasteners to the hood support brace and by body rivets to the upper body beneath the rubber bumper.
Hardware: Specific hardware types are mentioned, such as slotted washer-head hex screws for spark arrestors, and rivets for body components.
Torque Specifications: The manual repeatedly emphasizes the importance of torquing fasteners to specification, particularly for muffler and exhaust manifold connections, to ensure a good seal and prevent undue stress.
Compression Springs: Used in the muffler-to-manifold connection, these springs allow for movement and prevent stress. The manual warns against overtightening to avoid coil binding.
Gaskets: New exhaust gaskets are recommended whenever servicing the muffler system.

Usage Features:

Step-by-Step Procedures: The manual provides clear, numbered steps for each operation, making it easy to follow.
Photographic Illustrations: Each significant step is accompanied by a photo (e.g., Photo DE-1, DE-2, etc.) to visually guide the technician, showing the exact location of fasteners, components, and tools.
Model-Specific Instructions: Procedures are broken down by specific Argo models and even by serial number ranges, acknowledging variations in vehicle design over time. This ensures that technicians apply the correct method for the particular vehicle they are servicing.
"NOTE" Sections: These sections provide additional important information, such as collecting spacers, specific design features of older models (e.g., straight-cut tailpipes on 6x6 Vanguards prior to S8131), or the need for optional parts when replacing older components.
"IMPORTANT" Sections: These highlight critical aspects of the procedure, such as replacing exhaust gaskets, the importance of correct torque, and avoiding coil binding of compression springs.
"WARNING" and "CAUTION" Sections: These emphasize safety precautions, such as avoiding servicing a hot exhaust system to prevent burns, wearing eye protection, and not touching hot exhaust components after engine operation.

Maintenance Features:

Muffler Removal and Installation: Detailed instructions are provided for removing and installing the muffler assembly, including disconnecting from the manifold, unbolting from the body, and handling the shroud.
Muffler Disassembly and Assembly: For Conquest models, the manual covers disassembling the muffler assembly, including removing heat shields, fasteners, and separating the tailpipe/spark arrestor.
Spark Arrestor Cleaning: A dedicated section outlines the procedure for cleaning the screen-type spark arrestor, including removal, shaking loose particles, cleaning with a wire brush (and oil solvent if necessary), and inspection for breaks.
Spark Arrestor Maintenance Schedule: It is recommended to remove, clean, and inspect the spark arrestor every 50 hours of engine operation.
Exhaust Gasket Replacement: Emphasized as an "IMPORTANT" step, new exhaust gaskets are recommended whenever the muffler system is serviced.
Intake Duct Removal and Installation: Instructions cover removing and installing the intake duct, including disconnecting fuel lines, removing fasteners, and navigating the duct in and out of the engine compartment. For Conquest models, this involves splitting the upper and lower body and drilling out rivets.
Exhaust Ducting Removal and Installation: Procedures for removing and installing the exhaust ducting, including fasteners, body rivets, and aligning components.
Hardware Replacement: New hardware is recommended for muffler-to-manifold connections, even if compression springs are reused.
Component Inspection: Technicians are instructed to inspect components like the spark arrestor for breaks or weldment issues, implying replacement if damage is found.
