Gear tooth question & the "Yugo" od surface grinders

This pinion is a spur gear, engaging a rack on the underside of the table. Apparently, a previous owner had the machine apart and had lost the original pinion. He then put in an 'off the shelf' pinion, but the result was a 'notchiness' as the pinion engaged the rack. I took this pinion off and determined it to be a 16 pitch x 18 tooth gear.
