The pair has considerable tackling experience with Love having coached Tonga at the 2003 Rugby World Cup and Shelford representing Scotland at international level.
As directors of the New Zealand Sports Academy, they have also previously helped NRL club the New Zealand Warriors.
Tackling was one of coach Brenton Sanderson's constant annoyances last year and despite making it a focus over the pre-season, the Crows were out-tackled 73-47 by Essendon in their round one loss.
Sanderson said it was a "fortunate coincidence" that Love and Shelford were able to offer their expertise, as they were in Adelaide to observe his club's football program.
He said the duo offered technical tips on Tuesday, but would be available for individual consultation if necessary.
"They actually came to us to have a look at our program. I asked if it was ok while they were here, with their backgrounds, if they could just take us through a little tutorial," Sanderson said.
"We might send a couple of guys to them in the next two days just to make sure any little problems or little deficiencies might be able to be ironed out.
"We didn't want to bash and crash into each other today... it's just more about some technique stuff and some triggers that help our guys with some of the method.
"A low tackle count last week and tackling was a major concern for us last season, so the opportunity to get a bit more advice has been good for our guys."
Despite the disappointing 35-point loss to the Bombers, Sanderson won't swing the selection axe ahead of his side's round two clash with the Brisbane Lions.
He said he would only make "one or two" changes to the round one side, but admitted several players would enter Saturday's match on thin ice.
"If you play poorly consistently, you're not going to be playing for us," he said.
"If you get a game this week, coming off a bad one, you can't afford to have another bad one.
"When you haven't got the depth, players continually get games when they're out of form but if you've got depth you have to reward form.
"I'm not afraid at all to throw the line-up around if it means we've got a team in form."
Sanderson declared defender Luke Brown ready to go after bruising his foot against the Bombers, while Ian Callinan (knee) and Josh Jenkins (jarred wrist) both need to prove their fitness in Wednesday's main session.
Young gun Brad Crouch continued to impress in the SANFL last Thursday night, with 31 possessions, seven marks and four clearances playing for West Adelaide.
Sanderson admitted the 19-year-old was close to making his debut.
"I loved his game for 'Westies' last weekend, so he did everything right to put his name in front of match committee.
"He'd be one that's right in the mix."
