COMPLETE DISASSEMBLY (CONTINUED)
(6)
Remove air cylinder with bearing from drive hub. The air cylinder bearing is a slide fit
on the drive hub and is affixed to the drive hub with a thin coating of Loctite
®.
You may
need to strike the hub, or an object inserted in the hub with a rubber mallet or similar
soft face hammer, while pulling the cylinder upwards to break the
Loctite
®
seal.
(7)
Remove piston/cone sub-assembly to access o-rings.
B. FRICTION DISC & SPRING REPLACEMENT
(1)
Follow steps 1
– 4 from COMPLETE DISASSEMBLY instructions above.
(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
discs move freely in the drive slots of the sleeve.
C. O-RING REPLACEMENT
(1)
Follow COMPLETE DISASSEMBLY instructions above.

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

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