housing than housing has some micro split / crack. Goto ID 100
020
Oil is Leaking
Oil Leakage from Cover
The sealing liquit under cover is split/defect. Disassemle the cov-
er and put new sealing liquit. Assemle the cover and tighten the
bolts. If still same problem goto ID 100
021
Gearbox is moving regularly
on its mounting point
You are using Torque Arm
The movement of gear box is because of the runout of the shaft
which you assemle the gearbox. This has no bad affect or harm
to the gearbox and is normal unless you are using torque arm.
022
Gearbox is moving randomly
on its mounting point
You are using Torque Arm
The movement of gear box is because of the runout and clear-
ance of the shaft which you assemle the gearbox. Check the
clearance of the assemling shaft and the clearances on your ma-
chine. This has no bad affect or harm to the gearbox unless you
are using torque arm.
023
Motor is heating up
Motor is running over its nom-
inal current
The motor power is not enough or some overload to the motor is

The radial load or poligon effect of the chain may have caused
the damage. Check also if the assembly bolts are loosened or the
plate you assemble the gearbox is rigit enough. Check if you are
using the correct diameter of chain drive and you are not exceed-
ing max. allowed radial load. Check the position of your output
element and re-calculate your radyal load and check if this fit to
the maximum allowed radial load. Goto ID 100
026
Output Shaft is Defect
You are using chain drive or
pinion gear
The radial load or poligon effect of the chain may have caused
the damage. Check also if the assembly bolts are loosened or the
plate you assemble the gearbox is rigit enough. Check if you are
using the correct diameter of chain drive and you are not exceed-
ing max. allowed radial load. Check the position of your output
element and re-calculate your radyal load and check if this fit to
the maximum allowed radial load. Goto ID 100
027
Gearbox is stopping too late
You are using braked motor
