Notes on Timing Marks
General notes on timing, markings
Shown on engine 112
The four copper plates of the timing chain facilitate the assembly when putting on timing chain. Each copper plate (1) must be matched with one of the
markings (camshafts 4/ 5, balance shaft 3 (M 112) or guide wheel 3 (M 113) and crankshaft 2).
Due to unequal length of timing chain paths, the engine must be cranked up to 14 times, until the copper plates are matched again with the markings.
