Hi Frankl..A fly press or small hydraulic press is required to replace these gears. Note before fitting the 'captive' gears, that are held in place by the pressed on gears on each shaft, are not identical..The gear on the mainshaft is drilled at 3 points for lubrication, the layshaft gear isn't.
You don't need a measurement to position the fixed gears...just press them on until they wont go any further..(the end of the spline)..This will still allow the captive gears to rotate freely....Ian
