a machined knurl pattern. When the collar is tightened, the specialized hardened

•
(Fig. 1,3) Knurled balls bite into the
radius to eliminate unwanted
movement.
•
(Fig. 2A, 2B) Even though the knurled
balls eliminate unwanted pad
movement, the collars must be evenly
tightened to reach their full locking
strength.
1. Slide collar cover (B) off pad collar and over ball (C).
2. Loosen collar bolts (A). Loosen the collar bolts only to the point where the
ball slides in. This is easier than taking the collar halves completely apart.
3. Clamp collar evenly on ball (C). See page 15.
4. Slide collar cover onto collar.
