Equipment initially kicked into touch (3)
I believe the answer is:
kit
'equipment' is the definition.
(I know that kit is a type of cogwheel)
'initially kicked into touch' is the wordplay.
'initially' says to take the initial letters.
The first letters of 'kicked into touch' is 'KIT'.
(Other definitions for kit that I've seen before include "Equipment; young ferret" , "Football top, shorts, stockings and boots?" , "In strip" , "Supplies" , "Necessary equipment" .)
