40. Wind a rope round the bevel pinion shaft (Ø 34,8 mm)
and co nnect a spring balance to the rope (shaft without the
cassette seal).
41. Measure the rolling resistance P two, three times. Read
off the value, while the shaft is rotating. In the beginning
more power is needed.
The correct rolling resistance should be 3 0 N --- 5 0 N ( 3 --- 5
kg)
42. Tighten the shaft nut, if necessary.
IMPORTANT! Take a note of the rolling resistance value,
since it is needed when adjusting the differential bearing
rolling resistance.
H. Fitting differential onto b racke t
43. Fit the o---ring (27) and the washer (26) into the differen-
tial.
Note! Grease the parts to keep them in place during fitting.
44. Position the differential onto the bracket. Do not move
parts (26) and (27). Ensure, that the bearing outer races
are in places fully home.
45. Refit the bearing caps according to the marks and
screw in the fixing bolts and tighten them but not too hard.
46. Screw the adjusting nuts into place in a suitable way.
I. Adjusting tooth backlash and differen-
tial bearing pre---load:
47. Place the dial gauge (1) stylus against the crown wheel
tooth ( meas ure at leas t on thr ee teeth). Adjust the tooth
backlash by slackening (if too small backlash) or by
tightening (if too big backlash) the adjusting nut (3) (i.e. by
moving the differential axially so that the bearing clearance
is kept as zero or slightly pre---loaded).
The backlash must be between 0,17---0,23 mm.
