7.2.2 Camshaft
Figure 127
– Cam Timing Gear Assembly
Clamp the camshaft between the heavily padded jaws of a vice and fit the large inner gear, the alloy
spacer and the small outer gear to the flange at the rear of the camshaft: clean and prime 4 new AN4-
H5A bolts and the cam flange threads with Loctite 7471 cure accelerator, align the inner gear so that
the alignment hole on the camshaft flange aligns with the hole in the inner gear.
Hold that position and fit the spacer and the outer gear as shown in the drawing above and secure in
place with the AN4 bolts with Loctite 620 Retainer applied to the threads. Torque the value given in
Table 9 and lockwire the bolts in place in pairs as shown above left (also refer to Section 3.9).
Oil the cam bearing surfaces and then place the camshaft into one half of the crankcase and check for
end float between the rear flange and the rear housing with feeler gauges as shown below (right). Value
measured must be within the limits given in Table 12 (around 0.10mm is typical). Record the value.
