DISASSEMBLY CONTINUED:

(4)

Remove inner retainer ring from the drive hub.

(5)

Next, remove sub-assembly consisting of the piston, bearing & cone. The disc
package (consisting of friction discs, drive discs & springs) will now be accessible.
Note that the first drive disc contains a milled hole. It is important that this disc is
returned to the top during reassembly to line up with the screw in the cone.

B. FRICTION DISC & SPRING REPLACEMENT

(1)

Remove the drive discs, springs and friction discs.

(2)

Drive discs should be clean, dry and free of burrs or nicks.

(3)

Reassemble drive & friction disc section according to reference drawing using new
friction discs, springs and steel drive discs as necessary.

(4)

Assure that drive discs move freely on the drive hub and that the lugs of the friction disc
discs move freely in the drive slots of the sleeve.

Note Regarding Wave Spring Alignment:
The beginning of the coil of each spring should be placed in the same relative (O-Clock)
position to the drive hub to assure equal separation of the drive disc.

C. O-RING REPLACEMENT

(1)

Separate cylinder and piston/bearing/cone sub-assembly taking care not to bend the
pins which connect them.

(2)

Inspect O-ring seals. If worn, replace using new O-rings that have been lubricated with
an O-ring lubricant such as Dow Corning

4 Compound or equivalent.

(3)

A very thin coat of O-ring lubricant should also be applied to the inner walls of the
cylinder.

D. REASSEMBLY

(1)

Place the piston/bearing/cone sub-assembly over drive hub making sure the screw
head in the cone is inserted in the corresponding hole milled in the drive disc. This
prevents the cone from skidding on the drive disc.

(2)

Replace the inner retainer ring on the drive hub.

(3)

Inspect the inside diameter of the bearing in the air cylinder. If Loctite

residue is

present, gently scrape and assure that the surface is clean.

(4)

Place a small amount (dab) of grease (Mantek

Elite Red or equivalent) on the pins

that connect the air cylinder and piston.

(5)

Apply a thin coat of Loctite
