8. Fix tool no. 293975 into a vice, assemble all parts on
it including a test shim (P) .
Screw in tool nut to lock the tool and using a depth
gauge measure dimension (H7) between tool end
and end of the inner screw.
Adjuster ring thickness (S2) is given by:
S2 = H6 + P + S1 ­ H7 +0.2
where:
P = Test shim
S1 = Pinion shaft position adjustment shim, as found
in the previous paragraph.
0.2 mm = Increase necessary to compensate for
bearing increased preload deriving from tightening of
the pinion shaft locknut
