Tuning and setup

Change draw weight and set tiller: Black Eagle and C.P. Oneidas

The small black timing cable keeps your cams working together, and the timing hub locks it. Small weight changes can be made with the hub locked; anything bigger means unlocking it, turning the bolts evenly, re-tillering and locking it again.

  • Difficulty Moderate
  • Time 20–40 minutes
  • For 10 Oneida models

From Oneida's Black Eagle manual, whose tiller and timing pages are missing from our copy. Extreme Eagle, Falcon and Switchblade pending our confirmation.

All how-to guides

We're still double-checking this guide against how we do it in the shop. If anything doesn't match your bow, stop and text us or call 270-318-2020.

Before you start

  • Never draw the bow with the timing hub unlocked.
  • Never set the bow above its rated weight.
  • Make sure nothing can stop an outboard limb during a shot; it damages the timing system.
  • Wear safety glasses. Never dry-fire.

Steps

  1. Find the timing cable (the small black cable through the riser) and the timing hub (Fig. 2).
  2. Look first: a frayed or kinked timing cable or a bent or cracked timing wheel needs replacing; send it in or call us.
  3. Make small changes of up to 2 turns on each bolt with the hub still locked, as long as both bolts get the same turns.
  4. Compare how tight the timing cable feels at each end. If one end is tighter, unlock the hub and re-tiller.
  5. Loosen the timing hub for any bigger change.
  6. Turn the bolts evenly, switching between them: clockwise adds weight, counter-clockwise removes it.
  7. Measure tiller square from the string to the nose of each cam; top and bottom should match.
  8. Adjust one end at a time: turn a bolt clockwise to bring that cam nose closer, counter-clockwise to move it away, re-measuring as you go.
  9. Ask us before setting timing cable tension. If your bow has a take-up spool, Oneida's 1990s method is about 1/8 in of flex under firm finger pressure, set with the timing screw loose.
  10. Lock the timing hub before you draw.
  11. Check the weight on a scale and stay within your range.
  12. Check brace height against your model page. Oneida raises it by twisting the string in a bracket press set 23 in apart.

Tips

  • Grease the fiber washers under each weight bolt lightly with lithium grease, not bearing grease. The riser's stainless thread inserts need no grease unless the bow is very wet. (Black Eagle Manual p.2)
  • If a limb hits something during a shot, check tiller before you shoot again. (Dealer Instructions p.17)
