Determine dimension x for the thickness of the lower circlip (see No. 8 in → REMOVING TRANSMISSION HOUSING ).
Sample calculation of dimension x

x = a - b = 28.5 mm - 26.8 mm = 1.7 mm

Determine the thickness of the circlip in accordance with the table.

Force circlip and ball bearing onto the drive shaft with the driver sleeve 30-100 .
Determine and use the thickest circlip that can still be used.
