a)
To fit the 3rd and 4th speed synchro collar:
Fit the 3rd and 4th speed synchro collar (42) on the hub (43), the shouldered face towards the 3rd speed and
corresponding to the paint marks.
b)
Determine the thickness of the ball pads. Fit a ball pad (44) of one thickness (for example 5 mm) in a housing.
With a set of feeler gauges, measure the clearance
'If" of the ball pad in its housing; take this measurement
by sliding the feeler gauge between the ball pad and the hub (for example 0. 35 mm), this gives the height of
the housing as 5 t 0.35 = 5.35 mm.
Knowing that the ball pad should have a clearance of 0.04 to 0.25 mm, select a ball pad which will permit a
minimum clearance being obtained, therefore in +lle example select a ball pad with a thickness of 5. 25 mm.
NOTE - Mark the housing SO that it corresponds to the thickness of the ball pad determined above and recommence
the same operation for the other two ball pads (the thickness of the three ball pads can be different).
