Wrench, say, with money to be raised (4)
I believe the answer is:
tool
'wrench say' is the definition.
(wrench is a kind of tool)
'money to be raised' is the wordplay.
'money' becomes 'loot' (loot is a kind of money).
'to be raised' shows that the letters should be reversed in order.
'loot' written backwards gives 'TOOL'.
'with' is the link.
(Other definitions for tool that I've seen before include "Cat's-paw; impress design on" , "Appliance" , "Drive motor skilfully" , "Pawn" , "organ" .)
