Refitting The Primary Drive Gears And Checking Backlash - Ducati Monster 696 2009 Manual

N 6.3

Refitting the primary drive gears and checking backlash

Fully degrease the crankshaft splined end and the corresponding spline on the primary drive gear.
Check that the key (C) and internal spacer (D) are in position on the crankshaft.
Fit the driving gear (B) onto the crankshaft with the oil pump drive sprocket facing the crankcase.
Temporarily secure the gear with the washer (6) and nut (5).
Important
If fitting a new primary driving gear (B), check the backlash.
To check the gear backlash, temporarily fit the clutch drum (1) complete with internal spacer (4), driven gear (A), roller bearing (3)
and internal bush (2) on the gearbox input shaft. Fix a dial gauge to the engine crankcase, positioning the stylus against a gear
tooth.
Turn the driven gear (A) to mesh the teeth and check with the dial tool that backlash ranges between 0.05 and 0.07 mm.
Repeat the check at 16 different points of the driven gear.
If the measured values are outside the permissible tolerance limits, try changing the position of driven gear (A) on the input shaft,
leaving the driving gear (B) on the crankshaft. If the backlash is still outside the tolerance limits, renew the primary drive gear
pair (1).
