Other than moving fast, no other option I know of. Thats why I use the 603 retaining compound version for shafts, longer working time before it says 'enough, its staying THERE' on you. Either version can always be removed with heat from a small torch, cleaned (it will leave some goo behind that can be scraped off), and redone.
Thomas, most if not all Loctite products cure in the absence of air. I suspect in your case, the closer the fit, the faster it will begin to cure, since there is less air between the parts. The 648 can fill up to .006". My thought is that closer fits, which I assume you had will cure faster...it could be the specs are based on maximum clearance. Bill
After heating to remove it, its best to clean it up and start over, it doesn't reset again. At best it will be gritty enough to keep a screw from loosening.
You can increase the working time by chilling the Loctite. The data sheet for 680 shows the cure time as a function of temperature. - Terry

If quite warm, Terry is right,, it could speed up the curing, just like with epoxy, and chilling it and parts will help. I've had epoxy with an hour pot life go off in minutes in a hot workshop in summer.
