Using a feeler gauge, measure the planetary pinion gear thrust clearance.
Standard clearance: 0.2 - 0.5 mm (0.008 - 0.020 in.)
Maximum clearance: 0.5 mm (0.020 in.)
If the clearance is greater than the maximum, replace the planetary gear assembly.

Standard inside diameter: 19.025 - 19.050 mm (0.7490 - 0.7500 in.)
Maximum inside diameter: 19.100 mm (0.7520 in.)
If the inside diameter is greater than the maximum, replace the flange.
