Which locking method secures crown wheel bolts?

  • A.Thread locking compound or a locking plate
  • B.A spring washer beneath each head, which maintains the clamping load as the components expand and contract in service
  • C.A split pin
  • D.Wire locking through drilled heads, which is the method used on every application where vibration is present

Answer: A

Crown wheel bolts are highly loaded and are secured with a thread locking compound or a tab washer, and many are specified as single use. Spring washers are inadequate at these torques. Wire locking is used in aviation rather than in automotive final drives. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. The shared behaviour explains why these belong together and the differences explain why both exist.
