23. Using differential preload adapter DW240–130, turn
the differential gear assembly right and left 2 or 3
times to allow the bearing settle.
24. Using differential preload adapter DW240–130 and

28. Using differential preload adapter DW240–130, turn
the differential gear assembly right and left 2 or 3
times to allow the bearing settle.
29. Using differential preload adapter DW240–130 and
a small torque wrench, measure the preload of the
differential gear. From this valve deduct the valve
measured in step 23. This is the preload of the
counter driven gear.
S Preload:

If the preload of counter driven gear does not satisfy the
specification, select the adjuster shim from the table below
and remeasure the valve. Until the valve is within the spec-
ification, repeat the procedure.
Notice : When the preload is larger than the specification,
select a thinner adjuster shim. When the preload is smaller
than specification, select a thicker adjuster shim.
S Adjuster shim thickness: mm (in.)

brake spring compressor bolt/nut DW240–060–01,
install the snap ring.
Notice : Make sure that the snap ring is installed in the
groove of the transaxle case correctly.
37. Using a dial indicator, measure the 1st & reverse
brake piston stroke while applying and releasing
392–785 kPa (57–114 psi) of compressed air.
Notice : If the piston stroke is non–standard, inspect the
discs, plates and flange. Piston stroke 0.6 1.3 mm (0.024
0.051 in.)
38. Using counter drive gear installation adapter
DW240–100, brake spring compressor bolt/nut
