An anti-backlash rack and pinion drive system comprising a pair of spur gears on parallel shafts engaging a rack with countertorque preload imposed by a positive timing belt engaging a pair of pulleys respectively coupled to the shafts. Slack on one side and a resilient transverse load applied to the other side of the belt provides counterspur gear tooth pressure on the rack equal to the maximum drive load effected through reversible rotation of one of the shafts.
