Judge takes that object for repair (5)
I believe the answer is:
refit
'repair' is the definition.
(I've seen this before)
'judge takes that object' is the wordplay.
'judge' becomes 'ref' (referee).
'takes' is a charade indicator (letters next to each other).
'that object' becomes 'it' (pronoun for an inanimate object).
'ref'+'it'='REFIT'
'for' is the link.
(Other definitions for refit that I've seen before include "Overhaul (ship)" , "Restoration and repair of equipment etc" , "Overhaul (ship's equipment)" , "Process of improving equipment" , "prepare for employment again" .)
