MANUAL GEARBOX

21 - 33

The checking of the conical distance is performed by means of the CV239 - 01

control device, which materializes the toothed crown axis and by means of a spacer

CV 239 - 02, with the height H = 48,5 mm. The height (H) of the 48,5 mm spacer plus radius

The distance value (X) measured between the spacer and the pinion face shall be:

X = 59 mm - 58,5 mm = 0,5 mm (when the actual value is A = 59mm).

Attach the right half crankcase on the support, with the separating plane upwards.

Place the secondary shaft.

Place the left (1) half crankcase and tighten it by means of several screws.

Tighten the attachment spacer screws on the half crankcase at the required couple.

Introduce the CV 239 -01 control device.

Place the CV 239 - 02 spacer at the end of

the differential drive pinion

Measure by means of a thickness gauge

the distance ( X) between the spacer and the

device shaft :

1. The distance value measured is smaller

than the normal one (0,5 mm) .In this case,

replace adjustment washer for the distance

between the conical mechanisms with a thinner

one.

2. The distance value measured is bigger than

the normal one (0,5mm).In this case,

replace the adjustment washer for the conical

distance with a thicker one.

The thickness of the adjustment washers is 1,8 - 3,8mm, every 10 hundredths of millimeter.

The measurement of the value ( X) is performed by means of the speedometer endless

screw (G.B. 365 ) or the flange nut (G.B. 51 C ) tightened at the required moment

( 10 -12 daNm).

Take out the checking device.

Dismount : the spacer; the left half crankcase; secondary shaft.
