20.Set up a dial indicator, as shown in Figure 68, and while holding the spanner nut with a leather glove, push and pull it toward the tailstock to determine the amount of end play. The correct amount of end play is 0.001"– 0.002".

21.Loosen or tighten the spanner nut until end play is 0.001"–0.002", tighten the spanner nut an additional 1⁄8 turn to preload the bearings.
22.Put on a pair of leather gloves and remove the spanner nut.
23.Reinstall the speed sensor with the screws you removed earlier (see Figure 69). Make sure the cord does not touch the pulley sheaves or hang down near them.
