Part of the harness said to be put back (10)
I believe the answer is:
reinstated
'be put back' is the definition.
(to reinstate something is to bring itback)
'part of the harness said' is the wordplay.
'part of the harness' becomes 'rein' ('rein' is part of 'harness').
'said' becomes 'stated' ('state' can be a synonym of 'say').
'rein'+'stated'='REINSTATED'
'to' is the link.
(Other definitions for reinstated that I've seen before include "being put back" , "brought back" , "Got back to work" , "restored" .)
