Delta-1 Drag Wheel Beadlock Assembly Procedure

  1. Verify all female threads in the wheel are free of foreign matter – compressed air is recommended. For Top Fuel wheels skip steps 2 and 3.
  2. Apply 2 drops of Loctite 242 blue thread locker on course threaded end of stud. (5/16” studs for PS1 & PM1)
  3. Thread course end of stud into wheel. Torque to 12 in-lb (1 ft-lb.) to ensure the stud is seated (PS1 & PM1 has 36 studs per wheel).
  4. Insert Wheel into tire.
    *Do not allow the wheel to rest on a surface using the beadlock studs as a stand
  5. Locate tire bead onto tire register.
    *Verify the tire’s bead bundle is clean and free of all potential lubricants and debris.
    Acetone and lacquer thinner are acceptable cleansing agents.
  6. Position beadlock ring onto the tire, over the studs or TF bolt holes.
    *It may be necessary to rest the wheel on an elevated surface, like a bucket, to allow the tire to hang below the wheel bead flange that you are trying to mount.
  7. Apply a minimal amount of nickel based anti-seize to spherical surface of spherical washer.
  8. Place spherical washers on the bolt-on beadlock ring.
  9. Apply an applicable amount of nickel based anti-seize (or COPASLIP or equivalent) to fine threaded portion of stud or TF bolts.
  10. Thread on all nuts or bolts by hand (finger tight only).
    *For a tire with a thick bead bundle, it may be necessary to start 4 nuts onto 4 studs without using the spherical washer to allow enough bead compression throughout the bolt-on ring to start the remaining 14 nuts using each spherical washer. After the 14 have been started, go back to the first 4 nuts and re-install using the spherical washers.
  11. In a “star pattern”, torque nuts or TF bolts to 100 in-lb (8.3 ft-lb.) until each nut has reached initial torque requirement once.
  12. Continue to torque nuts or TF bolts in star pattern to value “A” on the chart below until each nut has reached torque requirement once.
  13. Continue to torque nuts or TF bolts in star pattern to value “B” on the chart below until each nut has reached torque requirement once.
  14. Re-torque all nuts or TF bolts to value C on the chart below in a circular pattern two full revolutions around the bead-loc ring.
  15. Re-torque after each pass.

Torque Values – Values Based on a Lubricated Fastener

PS1 and PM1 TF1 Torque Pattern
A 175 in-lb (14.6 ft-lb) 200 in-lb (16.7 ft-lb) Star
B 225 in-lb (18.8 ft-lb) 275 in-lb (22.9 ft-lb) Star
C 264 in-lb (22 ft-lb) 325 in-lb (27.1 ft-lb) Circular (counter or Clockwise)

Due to the induced bead-loc ring deflection caused by the thicker tire bead bundle (approximately .950 thick) on the Goodyear 1230 or similar tire, it is recommended that the bead-loc rings used in those applications are only used with tires of equal or greater bead bundle thickness.
