1 Bevel gearbox for models 4028 C - 4032 C - 4036 C
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.
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 500 mm long fastened to the shaft when checking the gear back-lash. The values stated
on the drawing are only valid for a lever with a length of 500 mm. Gear back-lash must be adjusted
using shims at A, B and C.
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.
Seals D and E must turn as shown.
Important, when fitting the gearbox to the machine:
Use LOCTITE 242 to lock the 4 bolts securing the gearbox to the machine frame.
