G . Assembling the planet carrier
29. Clean and check all components. Replace any
defective parts.
30. Lubricate needle bearings (16).
31. Make sure that the radial ports and axial channels
for lubrication of shafts (8) are not blocked.
R
EMINDER
Tractor speed can be between 30 and 40 kph.
Other speeds are obtained by turning the pinion gears
and sun gears of the Speedshift epicyclic gear train
(Fig. 1).
All sun gears do not have the same number of teeth:
- sun gear (6): 36 teeth;
- sun gear (7): 39 teeth.
N
OTE: The text and figures in this paragraph concern
reassembling a planet carrier for a ground speed of 40
kph.
32. Put the output sun gear (6) in the gearbox (9),
turning the sun gear lubricating grooves towards
side "F" of the unit (Fig. 13).
33. Install the needle bearings (16), with a spacer (14)
inserted in a pinion gear (12).
34. Put an “assembled” pinion gear in the unit, the
18 tooth pinion turned as in Fig. 1.
N
OTE: Each double pinion gear is identified with
one, two or three punchmarks on one of its sides
which is not necessarily the 18 tooth pinion. In this
case, make the same marks on the previously
mentioned pinion using an appropriate pen. A
punchmark corresponds to the alignment of two
teeth.
35. Position washers (17).
36. Centre the pinion gears and washers with a guide
pin Ø 16 mm, L = 80 mm (Fig. 14).
37. Insert the pin (8) into the free bore on side "F" of
the unit (9) (Fig. 14). Fit it partially retracted
(Fig. 15), with the radial lubricating port “a” turned
outwards and the end of central channel “C”
turned towards side “F” (Fig. 14).
