Adjust axle through-drive axial play

1

Determine the measure (A) from the sealing surface of the through-shaft cap (1) the inner support surface of the outer raceway of the tapered roller bearing.


Use a depth setting vernier caliper and determine the measure (A) of the outer race of the tapered roller bearing (arrow) to the open sealing surface on the passing axle (1).

3

Determine the thickness of compensating washer:

Thickness of compensating washer = Measure (A) - Measure (B)

4

Install the outer race of the tapered roller bearing (2) with the compensating washer determined on the passing axle cap (1).

Utilize an appropriate mandrel over a workshop press.
