A tooth and adaptor assembly (10) for use on earthmoving machinery is provided. The assembly comprises an adaptor (12) configured to be mounted to a leading edge of a ground engaging component of the earth moving machinery, the adaptor having 5 an adaptor aperture (28) extending from a side surface of the adaptor at least partially into the adaptor. Furthermore, a tooth (36) is adapted to be received over a leading part of the adaptor, and to be releasably secured thereto, with the tooth having a sidewall defining a first aperture (60) which, when the tooth is received by the adaptor (28), is aligned with the adaptor aperture thereby to form a locking 10 passage. A coupling pin (30) having an engaging key is shaped and sized to be received in the locking passage. Finally, a retainer insert (34) is provided to be received in a pocket within at least one of the adaptor's side surface and the sidewall of the tooth, the retainer insert having a key receiving formation to interact with the engaging key of the coupling pin in order for the coupling pin, once received in the 15 locking passage, to rotate the retainer insert in the pocket to a locked position, in which locked position the coupling pin is secured in the locking passage with the tooth being secured over the leading part of the adaptor. co~ /c coo "It 1 (D ,~777 0 CO (D (D LO)
