Section 2: setup, tuning, periodic maintenance

Instructions for shock setup, tuning, and periodic rider maintenance is not covered in detail in this manual. Please refer to the Manitou Swinger Rear Shock Owner's Manual (PN 042105) for that information.

SECTION 3: GLOSSARY OF TERMS

Air Canister – Can that holds the air spring air in an air shock.

Air Preload Adjuster – Located on the reservoir of SPV shocks. It contains the red Schrader valve for setting the SPV pressure and a hex fitting for adjusting the air volume (air preload)

Bottom Out – Point at which a shock reaches full compression.

Control Eyelet (C-End) – Eyelet that is on the rebound adjuster end of a shock. The air canister is attached to this end on air shocks and the spring retention collar is attached to this end on coil shocks.

Damper Eyelet (D-End) - Eyelet that is on the damper body end of a shock. On SPV shocks, this is the end that contains the SPV valve and reservoir if applicable.

Damper Body – Section of shock that contains the damping system

Damper Piston – Piston in that controls the flow of oil during compression and rebound.

Damper Shaft – Shaft attached to the damper piston that connects the two moving sections (damping system and control eyelet) of the shock together.

Damping System - Controls compression and rebound rate (speed). The system also provides the peddling platform unique to shocks with the SPV technology.

DU Bushing – Teflon guide bushing pressed into the eyelets. Mounting hardware is inserted into the DU bushings and rotates within the bushing as need by the suspension design.

Eyelet – Found on each end of the shock, it is where the DU bushing and mounting hardware are and provides the connection between the shock and bicycle.

Internal Floating Piston (IFP) - A floating piston that separates damping oil from the SPV air chamber or reservoir.

Mounting Hardware – Spacers that allow shocks to be mounted into the wide variety of suspension designs.

Schrader, Air – Black in color, it is the valve for pressurizing the air canister in an air shock

Schrader SPV - Red in color, it is the valve for pressurizing the SPV system.

Seals: O-Rings - Black synthetic rubber with a round cross section. Primarily used for fluid

sealing.

Seals: Quad Seals - : Black synthetic rubber with an “X” cross section, primarily used for sealing air.

Seals: Wipers – Teflon ring, used for keeping debris out of quad seals, guiding the damper piston, and providing support.

Top Out – Point at which a shock returns to its full extension.

Section 4: air spring system and spv air preload, swinger air

WARNING: The Swinger Air uses compressed air to provide resistance to compression in place of a coil spring. You must be certain that the air canister is relieved of all pressure prior to servicing the air system. Failure to relieve air pressure could result in injury or possible death.

Sealing of the shock is accomplished through a series of o-rings, quad seals, and wipers. When the air canister is removed, these seals can be replaced from Seal Kit C.

1. Failure of an air shock to maintain air pressure is usually the result of defective or worn seals. If there is suspicion of an air leak, pressurize the air canister to 150psi from the adjuster eyelet Schrader Valve and the SPV Air Preload Schrader to 100psi. Locate the leak by spraying the air canister and Schrader joints with a mild solution of dish soap and water or submerge in a bucket of water. Bubbles will form in from the area of leakage.

2. For leaks at the adjuster eyelet or damper end of the air canister, refer to the detailed disassembly instructions contained in the section on Damping System Bleeding - Swinger Air. This will guide you on how to replace the applicable o-rings and seals. 3. For leaks at the Schrader valves, release all air pressure and replace the Schrader valve core or assembly as needed. The core is removed using a standard core removal tool. The assembly is removed by removing the core and unscrewing the assembly by inserting a 3mm hex into the center of the valve. 4. For leaks in the air preload reservoir area (4W Swinger), release all pressure replace the preload adjuster o-ring, Schrader valve core, or Schrader assembly as needed.
