Special requirements
Description
Gear puller
To remove
1 Remove the timing case cover, see Operation 6-1.
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 6-6.
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 6-7. 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 6-2.
