A-series bolt-on kit

1. To improve access to the crank pulley bolt release the upper of the two bolts holding the engine mount in place and swing the engine mount down.

2. Remove the crank pulley bolt.

3. Place the trigger wheel onto the pulley and hold loosely in place with the crank bolt, using a longer bolt if appropriate.

4. On MPI engines temporarily remove the belt tensioner

5. Remove the timing cover bolt indicated

6. Remove the timing cover bolt indicated

7. The crank sensor bracket sits on a spacer to hold it away from the lip of the timing cover.

8. Loosely secure the bracket on top of the spacer.  You will tighten this down later, if necessary adjusting the position within the slots to optimise sensor position.  On some models it may be necessary to relieve the belt tensioner bracket/crank sensor bracket to give adequate clearance.

9. Crank sensors come in a number of different lengths and cable exit styles.

10. Space out the sensor the approptiate amount such that the gap between sensor and teeth is 1mm.  Adjust the position of the sensor using the slot so that centre of the sensor is pointing at the middle of the teeth.

11. To align the trigger wheel first set the engine to Top Dead Centre, then spin the trigger wheel against the pulley so that the missing tooth is in front of the sensor.

12. Rotate the wheel clockwise by 9 teeth.

13. Tighten down the crank pulley bolt.  We recommend the use of either a lock-tab washer or threadlock on the bolt. Here you can see that additionally we have drilled a hole (at about 1 o'clock  above and to the right of the crank bolt) for a dowel or roll pin to ensure that the wheel cannot rotate under any circumstances.  This is also a good point to verify that the six bolts securing the wheel to the boss are nice and tight.
