Refitting the primary drive gears and checking backlash


Fit the driving gear (b) onto the crankshaft with the oil pump drive sprocket facing the crankcase.

Refitting the primary drive gears and checking backlash


Temporarily secure the gear with the washer (4) and nut (3).

Important

If fitting a new primary driving gear (b), check the backlash.

Refitting the primary drive gears and checking backlash


To check the clearance, temporarily fit the clutch bell (1) complete with the primary driven gear (a) on the gearbox primary 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 that clearance 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 primary shaft, leaving the driving gear (b) on the crankshaft. If still outside tolerance values, renew the whole primary drive gear pair.
