Swivel gearbox
Repair of the gearbox must only be carried out by competent persons with thorough
knowledge of such work. Gear and bearing back-lash must be within the stated values,
and the contact surfaces of the gear must be adjusted correctly.
Machines equipped with swivel gearbox can be adapted for operation at either P.T.O. = 540 or
1000 r.p.m. by turning the gearbox. Ill. 1 and 2 show the two mounting procedures.
Note: The position of the gearbox can be seen at joints
G
and
H
. Always take care that the
gearboxes P.T.O. labels are re-fitted after repair.
Illustration 3 shows the gearbox in P.T.O. = 540 r.p.m. operation. The number of teeth of the gear
wheels is shown on the drawing.
Use a crane or other lifting tackle when releasing the gearbox from the machine, - the gearbox
weighs about 70 kg.
Note the following:
Checking of gear back-lash, bearing back-lash and the contact surfaces can only be measured on a
clean and oilfree gear.
Use a dial gauge fastened to the gear when checking bearing back-lash, - never hit the shaft ends,
as the bearing may be damaged.
Use a lever of 500 mm length fastened to the shaft when checking the gear back-lash. The stated
values on the drawing are valid with a 500 mm long arm.
Apply an indicator colour on 3 - 4 teeth of one gear to check contact surfaces. Fit the tooth wheel
and turn the shafts. Dismantle the tooth wheel again and check the contact surfaces.
Lubricate bearing
B
and the tightening ring underneath with grease before assembling the collar
bearing. This bearing is not lubricated from the oil in the gearbox.
Lock nut
C
with LOCTITE 242 and tighten to 500 - 550 Nm. Tighten nut
D
to 20 - 100 Nm.
Lock bolts
E
with LOCTITE 270 and tighten to 55 Nm.
Important, when fitting the gearbox on the machine:
Use LOCTITE 242 for locking the 16 bolts, that secure the gearbox in the drawbar and the clevis.
