• To maintain the chain at the camshaft, fasten the chain to the chain wheel with a cable
retainer. The position of the cable retainer must be at the 11 o’clock position of the chain
wheel seen from the rear side of the engine. The position of the cable retainer is shown
in Figure 85 - 105.
To prevent small parts from falling into the chain slot cover the slot with a rag. The chain
must not be slip from the tooth of the chain wheel!
• Remove the TCMT by hand turning.
