4.5 Disassembly of the Element

4.5.1 Lay the element flat on a clean work surface.

4.5.2 Remove the side plate and clean for reassembly. If the

torque bar holes are elongated more than one-half the

diameter of the pin on the end of the torque bar, the

side plate must be replaced.

4.5.5 Remove the remaining side plate only if it is to be

replaced.

Whenever the element is removed and disas-

sembled, it is always good practice to replace

the release springs.

Figure 14

4.5.3 Remove the friction shoe assemblies, torque bars and

release springs. If the torque bars and springs come

out of the element with the friction shoe assemblies,

carefully tap them out of the backing plate cavities.

Note wear and replace as necessary.

4.5.4 Remove the air connection elbows and spiral snap

rings which secure the air actuating tube to the rim.

Smaller size elements do not use snap rings. Carefully

remove the air actuating tube from the rim and thor-

oughly inspect. Replace if necessary.

Note : The snap rings may no longer be required on

certain size elements. Also, rims manufactured before

1984 were counterbored at the tube valve hole to

accept the snap ring. This counterbore has been elim-

inated, and a second snap ring groove has been

added to the tube valve. See Figure 14.

4.6 Friction Lining Replacement

Use only genuine Airflex replacement parts.

4.6.1 Make sure the torque bars and release springs have

been removed from the backing plates.

4.6.2 For riveted friction shoe assemblies, drill the rivets

with a 15/64 inch (6 mm) drill and tap the rivet body

out. Larger elements have linings attached with flat

head screws and locknuts. Airflex special wrench p/n

304572 will aid in holding the locknuts during removal.

See Table 7.
