Removing the primary shaft seal
Use puller 9997003 for removing the seal.
NOTE:
The screw and socket must be unscrewed when tapping on the extractor.
Tap the extractor into the seal. Tighten the inner socket. Counter hold the outer part at the same time so that the extractor expands against the seal.
Tighten the screw in the extractor and remove the seal.
Check that no residue from the old seal is left in the gearbox.
