Standard backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 in.)

Referring to the table below, select thrust washers which backlash is surely within the specified range. Select washers of the same size for both sides.

Thrust washer thickness

THRUST WASHER THICKNESS SPECIFICATIONS

Thickness	Thickness
0.95 mm (0.0374 in.)	1.10 mm (0.0433 in.)
1.00 mm (0.0394 in.)	1.15 mm (0.0453 in.)
1.05 mm (0.0414 in.)	1.20 mm (0.0472 in.)

If the backlash is not within the specified range, install a thrust washer of a different thickness.
