⚙️ Key Features

  • Used for DP-S
  • Supplied within the gear housing assembly
  • Supersedes 3552662, 3857827 and 814357
  • 191 applications across six ranges
  • Quantity varies by assembly, most commonly two

🔌 Function

Holds a threaded joint together with a self-locking feature that resists the nut backing off under vibration.

⚠️ Common Signs of Failure

  • Nut found loose or backed off
  • Nut spins on freely by hand, showing the locking feature is spent
  • Thread stripped, picked up or cross-threaded
  • Corrosion between nut and stud

🛠️ Service Notes

  • Self-locking nuts are single use - fit a new one rather than re-using the old
  • Stud 941814 carries the same gear housing and DP-S note and is the matching fastener
