– Hydraulic lifter engine camshafts have 2 dots on the flange and 2 rings around the front of the
camshaft to indicate a hydraulic lifter camshaft. The photos above show a hydraulic lifter (260°
duration, non-roller) camshaft.
– If the camshaft in your hydraulic engine has a single ring around the front (285° duration) it must
be replaced with a current 2 ring camshaft and new lifters to suit at overhaul.
– Engines equipped with roller followers use a different cam which is not marked with ID rings. This
part can be easily identified by the more rounded shape of the cam lobes (Figure 77)

5.10.3.2 Cleaning
Clean out the 4 threaded holes in the rear flange with a 1/4” UNF tap.
Clean the camshaft with kerosene and dry.
Coat with engine oil or other corrosion preventative.
5.10.3.3 Inspection
Visually inspect the lobes for any abnormal wear patterns and any chipping around the sides of the
lobes. Any chipping or signs of wear through the hardened surface will require a new camshaft. Inspect
the lifters for signs of wear on the face. If replacing the camshaft the lifters must also be replaced.
The camshaft and the camshaft drive gears must now be inspected for structural integrity with MPI
(Magnetic Particle Inspection).
The overhauler must be aware that of the different types and combinations of camshafts and lifters
fitted to Jabiru engines over the years currently only three combinations are approved: a solid lifter
(zero ring) cam with solid lifters, a hydraulic lifter (260° duration, 2-ring) cam for hydraulic lifters and a
roller follower cam (rounded lobes) for roller follower engines. Engines with other configurations must
be updated to an approved configuration at overhaul.
