Skipper Marc Murphy and fellow veterans Bryce Gibbs and Kade Simpson were important but younger teammates Sam Docherty, Patrick Cripps and Nick Graham also did their share of the heavy lifting.
Weitering finished with 18 possessions and impressed with his poise down back.
The Tigers had only managed to win two of the nine games missed by Deledio in the past two seasons and they sorely missed their star playmaker.
Trent Cotchin, in his first game at the 'G since he went missing in last season's elimination final loss to North Melbourne, managed just one disposal in the first quarter before working into the contest.
He finished with 21 touches but Dustin Martin, Kane Lambert, Bachar Houli and Alex Rance had greater influence.
Ty Vickery booted three goals with Jack Riewoldt and Sam Lloyd each adding two, with Lloyd's pair pivotal in helping see off the Blues' challenge late in the last quarter.
Daniel Rioli showed flashes of brilliance and impressed with his defensive pressure with six tackles.
"I think we got out of jail really," said a relieved Hardwick.
"We were probably lucky that we were good enough at the end to win the game.
"We played pretty poorly it would be fair to say, but Carlton came in with a plan, did a pretty good job with it and were probably not quite at the level where they could finish us off."
Bolton agreed there were plenty of positives to come from the performance but added that valiant efforts without getting the win wouldn't be celebrated on his watch.
"We were disappointed and we always will be when the scoreboard doesn't go our way," Bolton said.
"It was an opportunity lost particularly when we win the inside 50 count.
"It always hurts when you don't win."
