Camshaft gear
To remove and to fit 15-7
To remove
Special tools:
Gear puller, PD.155C
Adaptors for use with PD.155C, PD.155B-5
1 Remove the timing case cover , see operation 15-1 .
2 Rotate the crankshaft until the marked teeth of the
crankshaft gear and the camshaft gear are in mesh
with the idler gear. The marked teeth of the idler gear
will not necessarily be in mesh with the marked teeth
of the other gears because of the different speed of
rotation of the idler gear.
3 Remove the setscrew and washer of the camshaft
gear. Put a suitable adaptor onto the end of the
camshaft and remove the gear with the puller and
adaptor (A). Ensure that the key in the camshaft is not
lost.
4 Inspect the gear for wear and any other damage
and renew it, if necessary.
To fit
1 Ensure that the key in the camshaft is fitted
correctly.
2 Remove the idler gear , see operation 15-4 .
3 Fit the camshaft gear to the camshaft with the
marked teeth towards the front and the keyway
correctly aligned with the key. If necessary, lightly hit
the gear with a soft face hammer to engage the key
into the keyway.
4 Fit the idler gear with the marked teeth in correct
mesh
, see operation 15-4 . If the camshaft has to be
turned and a valve hits a piston, disengage the rocker
assembly.
5 Fit the washer and the setscrew for the camshaft
gear and tighten the setscrew to press the camshaft
gear into position. Tighten the setscrew to 78 Nm (58
lbf ft) 8,0 kgf m. If a new camshaft gear has been
fitted, check the backlash.
6 Fit the timing case cover , see operation 15-1 .
