OPERATION No. ID 330- 3 : Overhauh'ng the gearbox
Put the adjusting fixture on a surface plate resting on the two ground bearing pads.
(In this position the pointer on
the dial gauge is at 55 mm from the centreline of the ground semi-circular bearing faces .)
Turn the figure "0" on the movable dial on the dial gauge opposite the large needle.
Note the position taken up by the needles on the dial gauge.
Example : totalising needle between 4 and 5; large needle on zero.
To measure the actual bevel pinion setting.

Put the adjusting fixture in place of the differential. Turn the adjusting fixture by means of the knurled
handle until the large needle of the dial gauge changes its direction of rotation.
Mark the information given by the needles of the dial gauge.
Example: totalising needle between 1 and 2; large needle on 82.
Bring the needles to the position in which they were in paragraph c
(in the exatiple chosen the totalising
needle was between 4 and 5; the large needle on zero) by pulling on the dial gauge spindle.
Release the spindle of the dial gauge slowly, counting the numbers of turns and fractions of turns described
by the large needle, until the point of the dial gauge spindle rests on the ground face of the bevel pinion.
Check that the dial gauge needles have taken up the position indicated in paragraph 1.
Example : the large needle has turned 1.45 turns, that is to say that the difference between the positions
when adjusting fixture 2044-T was checked on the surface plate (see paragraph c) and the point of the dial
gauge has moved forward 1.45 mm.
The actual bevel pinion setting "1" is: 55.00 t 1.45 = 56.45 mm.
The dimension etched on the ground end of the bevel pinion being for example: 56.70, it is necessary to
withdraw the bevel pinion shaft from the centreline of the differential by 56.70 - 56.45 = 0.25 mm.
This dimension represents the dimension "l",
which should exist when the adjustment is completed between
the centreline of the differential shaft and the ground end of the bevel pinion.
This will vary with each crown wheel and pinion.
The adjustment of the bevel pinion setting should be made by using the adjusting fixture 2044-T fitted with the
dial guage 2437-T (see P1.50).
This fixture is constructed so that the distance between the centres of the semi-circular ground bearing faces
and the two bearing pads is 55 mm. This number is etched between the two pads.
The measurement should not be taken from the face of the joint of the casing as this differs in relation to the
centres ofthe differential bearings . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .

Carefully clean the bearing faces for the differential bearings and the semi-circular faces of the adjusting fixture
2044-T. All the faces should be free from scratches or burrs.
