8. When the correct clearance is achieved tighten the locking set screw
against the adjusting screw.

adjustment procedure. If the minimum clearance is correct but the
maximum clearance at any tooth is greater than .020 inch (0,51mm),
replace the ratchet wheel and repeat the adjustment procedure.
Continue with the appropriate Adjust the Anti-Back-Up Dog adjustment
procedure below.
Anti-Back-Up Dog Adjustment for 12.7 MM Heads
This adjustment ensures that the anti-back-up dog engages each tooth of the
ratchet wheel at the end of the return stroke.
This procedure applies to 12.7 MM feeders including P/N 50849901,
50849903, 52049701, 51976101, 51976103, 51976105, 52497901,
52497903, 52497905, and 52497907.
For information about feeders, P/N 50849902, 50849904, 52049702,
51976102, 51976104, 51976106, 52497902, 52497904, 52497906, and
52497908, go to Anti-Back-Up Dog Adjustment for 15 MM Heads.
If the clearance between the anti-back-up dog and the ratchet wheel is too
small, the dog fails to properly position at the end of the return stroke. This
would allow the feed wheel to back up on the next forward stroke and fails to
advance the component carrying cardboard strip. If the clearance is too
large, the component carrying cardboard strip backs up a small amount
causing the components to become misaligned in relation to the pushers.
