Does the original belt on your TS2412 look like the fan belt off a car, or does the inside have ribs running down it? I ask because I have TS2424, it could be different.
On TS2424, the belt used is a ribbed belt. Two issues with link belts here, first is that a link belt will not run on those pullies, second is that a link belt is a downgrade, ribbed belts are better.
If TS2412 does use a V belt, it is possible you have the link belt inside out, the correct way is not obvious. The free tab ends on a link belt go to the inside, just opposite of how it naturally wants to curl.
