Wear Of Timing Chains, Sprockets, TENSIONING And Slide Rails
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
- Pay strict attention to cleanliness during removal and fitting!
- Lay removed engine parts on a clean base and cover them.
- Coat new parts with new engine oil before installation.
- For the chain, drive no wear values (such as chain elongation) are specified. Before disassembly, the engine should therefore be run and checked for noises in the chain drive area.
If there are noises in the chain drive area, replacement of the individual parts is recommended!
- During disassembly, carefully check the spare parts (sprockets, timing chains, tensioning and slide rails) for signs of wear, e.g. abrasion of the sprockets, signs of rubbing on the tensioning and slide rails.
NOTE:
- If in doubt replace the parts!
Visible symptoms of wear are still permissible, but if the wear is appreciable then the affected parts must be replaced!
