The marking on the head of the chain tensioner is unchanged (1-ring, arrow).
New intermediate shaft seal.
There is a wider groove in the intermediate shaft to accommodate the new sealing ring. The new sealing ring is rectangular (previously: O-ring) and
approx. 4 mm wide on the sealing surface (arrow, figure 9).
The new intermediate shaft-bearing flange with rectangular sealing ring is available for repairs on all engines (1997 to present) with a roller-type or
tooth-type chain. The new bearing flange (part number, 996 105 017 01) is available only with the sealing ring fitted. The sealing ring cannot be
replaced individually. The previous bearing flange with O-ring must no longer be installed.
