Repair:
Camshaft drive:
The following parts have been changed because of the conversion to the tooth-type chain for intermediate shaft drive:
1 - Drive chain for intermediate shaft
2 - Crankshaft
3 - Intermediate shaft
4 - Chain tensioner
Note:
Roller-type chains remain in use for driving the camshafts.
After existing supplies of the previous parts have been used up, the new parts can be used as replacements for all Boxster engine types M96.20,
M96.22, and M96.21.
A mixed configuration is not permissible, as the parts are matched with each other. The previous chain tensioner, part No. 996 105 180 54, is still
available and may continue to be used on engines that have the previous style drive chain installed.
