The side adjusters control the horizontal movement of the crown wheel relative to the pinion. It is normal, with a new or unmarked CWP, to set the backlash to 1/16", using this adjustment, after the depth of engagement, or meshing pattern has been set.
The depth of engagement is set by shims on post 1931 axles, located between the torque tube and the case. This controls how far the pinion sticks into the casing and will largely set which parts of the teeth are making contact and carrying the load. This adjustment is carried out with engineers blue, the objective is to get the pattern of blue into the centre of the tooth, on both sides at the same time.
The backlash adjustment also has an effect here so the 1/16" should be maintained.
It's a complicated and frustrating adjustment with the two variables interdependent. Complete silence is rarely achieved. However, the main thing is to avoid over-tight contact or over-deep meshing, which runs the risk of fracturing the teeth.
