-- Using a screwdriver -C- the position of the circlip -2- in the groove can be corrected through the hole in the Extracting Tool - Thrust Piece:T40413/13 .

Continuation for all vehicles

-- The circlip must engage audibly in the pinion groove all around.

-- After pressing check that the circlip is in the groove all around.
