Timing Chain: Testing and Inspection

Fig. 18 Timing Chain And Sprockets:

- Inspect the chain. If it can be moved back and forth in excess of 16 mm (5/8-inch) make a note that the timing chain should be replaced during assembly.

- Inspect sprockets for chipped teeth and wear.

- Inspect timing chain for damage.

- It should be noted that excessively worn sprockets will rapidly wear a new chain. Likewise, an excessively worn chain will rapidly wear a new set of sprockets.
