Catch up with the maintenance (8)
I believe the answer is:
overhaul
This clue is a double definition.
'catch up with' is the first definition.
(thesaurus)
'the maintenance' is the second definition.
(overhaul is a kind of maintenance)
(Other definitions for overhaul that I've seen before include "Examine and repair (machinery)" , "Examine and make any necessary repairs" , "Repair fully and renew" , "Inspect and repair" , "Pass - examination" .)
