cam belt change

[jpliddy]

hi all
i finally had my cam belt ,water pump ,tensioner .and idler changed the mechanic had not done this job before on this engine he got there ok. when he attempted to remove the bottom crank bolt he jammed a bar into the fly wheel at the back of the engine , it slipped a few times i was getting a bit concerned but eventually the bar held and the nut came off i have read before how tight this bolt can be and was concerned about his method i think he was some how jamming the bar into the flywheel teeth is that a method you all woud be happy with just to put my mind at rest ,
regards jim
