4.7.2 Gearbox assembly
For TL1, TL2 and TL3 with ball bearing
1. Position the lip seals (0885) inside the gearbox.
2. Heat the bearings (0700) up to 100°C. Fit the bearing to the lay shaft (0051) ensuring
it is pushed properly against the shaft shoulder.
3. TL1 and TL2. Put the spacer sleeve (0170) over the lay shaft (0051).
4. Secure the bearing with locking washer (0630) and the nut (0620). Use Loctite 243 to
glue the nut (0620) on the shaft. Secure the nut by bending one tooth of the locking
washer.
5. Fit the second bearing on the drive shaft (0050) in the same way.
6. Insert both shafts with the bearings into the gearbox while tapping smoothly on the
external bearing ring. (Pay attention to position of drive shaft.) Be sure not to
damage the seals (0885).
Continue with point 7.
For TL4 with taper roller bearing
1. Position the lip seals (0885) inside the gearbox.
2. Heat the bearing inner rings with rollers (A and B) up to
100°C. Fit the inner rings to the lay shaft (0051) ensuring
they are pushed properly against the shaft shoulder.
3. Secure the bearing inner rings with the nut (0620).
Secure the nut by tightening the set screws with torque
18 Nm.
4. Fix the bearing inner rings on the drive shaft (0050)
in the same way.
5. Remove the first two bearing outer rings (C) from the
lay shaft and drive shaft in the gearbox together with the
two bearing intermediate rings (D). Insert both shafts in
the gearbox and put the last two outer rings (E) in place.
Note! Be sure that the outer and intermediante rings are always assembled with the
original bearing.
6. Be sure not to damage the seals (0885).
