Figure 7. Cam Identification Markings
Hydraulic lifters can be removed for inspection using the following method:
Remove the rocker pivot shaft, rockers and pushrods from the cylinder to be inspected.
Remove the pushrod tube retaining circlips from the cylinder head and slide the
pushrod tubes out through the head.
Remove the hydraulic lifter adaptors from the crankcase.
Remove the lifters.
Whenever lifters are removed the working face of the cam and the lifter should be
inspected for damage. If damage is found, contact Jabiru Aircraft P/L or our local
representative for further guidance.

Head Bolts
Head bolts are torqued to 20 ft.lb. when cold.
Carry out this adjustment after five hours of operation and again after ten hours of
operation. The bolts should thereafter be checked annually.
6.10 Tachometer and Sender
Many apparent engine problems can be caused through inaccurate tachometers.
Where engine performance is observed to be outside limits, the tachometer should be
checked against a calibrated instrument.
Tachometer sender gap is 0.4mm (0.016"). The sender must have at least 60%
covered by the tags fitted to the gearbox side of the flywheel.
Ensure both tags are equal distance from sender.
6.11 Additional Checks
