Inspection
When the unit has been dismantled, each part
should be thoroughly cleaned and Inspected to
determine whether any parts should be replaced.
.
As a guide the planned new dimensions are given at
the end of this section. Inspect the front casing for
cracks, damage, etc. Examine the bores of the
operating cylinders for scores and wear. Check for
leaks from the plugged ends of the oil passages.
Examine the clutch sliding member assembly.

torted. Ensure that the ball bearing is in good
condition and rotates freely.
Inspect the clutch springs for distortion or collapse.
Inspect the teeth of the gear train for
damage.
If the sunwheel bush is worn, the gear will have to
be replaced, since it is not possible to fit a new bush
In service, because it has to be bored to the pitch
line of the teeth.
Inspect the face of the sunwheel front thrust ring
In the front casing. This should be renewed only
if deeply scored, and it is only subjected to sunwheel
rotation whilst overdrive Is in course of selection.
Inspect the uni-directional clutch. See that the
rollers are not chipped and that the inner and
outer members of the clutch are free from
damage.
Make sure that the outer member Is tight In the
annulus. Ensure that the spring is free from dis

there Is no roughness when it Is rotated slowly.
Examine the tall shaft sleeve (reverse spline) bushes.
Inspect the malnshaft splines for nicks and burrs.
See that the oil holes are open and clean.

scratches.
Inspect the operating valve for distortion and
damage
and see that it slides easily In its bore In the
front casing.
Inspect the relief valve body, "O" ring and ball, etc.
