Connect a strap to the element assembly. Apply tension that is sufficient to support the entire weight of the assembly.
For reassembly, mark the following components:
Coupling hub (1) and spacer (2) (if equipped) to drum (3)
Element assembly (4) , adapter for the element (5) , and adapter ring (10) (if equipped) to gearbox hub (7)
Disconnect air tubes (6) from the adapter for the element (5) and gearbox shaft (9) .If the clutch has roll pins for orientation, remove only the roll pins from the components that are being disassembled.Remove the bolts that connect the adapter for the element (5) and hub (7) . If the clutch has an adapter ring, remove the bolts that connect adapter ring (10) to the adapter for the element (5) .Remove the clutch assembly.
Lay the clutch assembly on a clean, level surface. Place the flange for the air tubes upward. Disconnect element assembly (4) from the adapter for the element (5) . Do not disconnect the adapter for the element (5) , bearing support (8) , and drum (3) . Lift these connected parts from element assembly (4) .Disassembling the Dual Elements

Operation with friction material that is less than the minimum allowable thickness will result in damage to the drum.
Inspect the friction shoes for wear of the linings. Linings with wear that is uneven may indicate a worn drum or misalignment.Measure the thickness of the linings. If the linings are worn to the minimum allowable thickness, the complete set of linings must be replaced. The minimum allowable thickness of the linings depends on the element that is used.
For the 4C-B200 Element , the minimum allowable thickness is 0.8 mm (.032 inch) .
For all other elements, the minimum allowable thickness is 1.5 mm (.06 inch) .Inspect the friction shoes and the drum for oil and grease contamination. Contamination will reduce the torque of the clutch.
Do not use a solvent for removing oil or grease without removing the element. Spraying a solvent into an installed element can cause a fire from the heat that is generated. Remove the element before cleaning.
Do not use compressed air for cleaning dust from between the friction shoes even if the material does not contain asbestos. The dust may irritate the respiratory system.Use a vacuum for removing the dust.
If oil or grease is detected, disassemble the element. Remove dust that is between the friction shoes with a vacuum. Clean the internal parts of the element. A light contamination of oil or grease may be removed with a solvent. Replace the lining if either of these conditions are found:
The lining is saturated with oil and/or grease.
The lining is charred from excessive heat.
Do not attempt to sand material that contains asbestos. Use the appropriate precautions for working with asbestos.
To check the lining for asbestos, clean the edge of the lining. The lining contains asbestos if the following composition is found: green stripe, yellow stripe and brass flakes. Carefully remove the linings. Dispose of the linings according to local regulations.
Use caution in order to avoid breathing dust that may be generated from handling any friction material, regardless of whether or not the material contains asbestos. If the dust is inhaled, the dust can be hazardous to you health.Wear a proper protective breathing device when handling friction material.
Inspect the surface of the friction shoes. If the linings are glazed, the glazing may be removed by lightly sanding the lining. Do not sand the lining if the lining contains asbestos. Replacing the Friction Shoes
