Oil control
The oil level is to be checked by removing the upper oil plug pos. A (ms.100-180) on the oil chamber or pos. G
(ms.80-90) on the gear. The oil has to be clean and the level has to reach the plug hole. Oil type; see the spare
parts list. If the oil is dirty it has to be changed.
A. Upper oil plug, oil chamber
B. Lower oil plug, oil chamber
C. Lower oil plug, gear
D. Inspection screw
E. Top oil plug, gear
F. Grease nipple
The oil is drained off by removing the plugs, pos. B and pos.
C (ms.100-180) or pos. C (ms. 80-90). In case of
contaminated oil, the seals and wear bushes must be
checked for wear and contamination.
When filling oil through the oil plug, pos. A (ms.100-180), the oil plug (pos. E) must be removed to allow the
venting of the gear unit. For ms.80-90, oil is filled through the oil plug (pos. G) on the gear.
Lubricate the outer sealing system with grease (see spare parts list). This takes place through the grease nipple,
pos. F, which is fixed in the propeller behind one of the propeller blades. Prior to reinstalling the propeller fill up
the hub with grease lubricant.
The motor casing must be inspected in the following way: Remove the inspection plug, pos. D, beneath the motor.
Any leak of oil or liquid can be seen immediately.
In case of irregular leakage, it is necessary to check the seal in the oil chamber. If in doubt, please contact Landia.
If it is necessary to dry up the motor windings, contact an electric motor repair workshop.
Equipment
The equipment should be inspected for wear and corrosion. The winch is to be lubricated with grease. Inspect
brake and lock. Retighten screws. If the screws are loose, remove them and lubricate with Loctite 243 prior to
reinstallation.
Disassembling/assembling
A major repair should take place at a workshop which is specialized in this type of repair. We can refer to a service
partner in your territory. Below please find some general conditions regarding disassembling/ assembling of
Landia mixer type POP-I. The drawing attached to the spare parts list shows the construction of the unit. Not all
parts can/should be removed, e.g. do not press the rotor off the shaft.
When disassembling the unit, handle the mechanical seals with care as they are not shock resistant. Prior to
reinstallation, all sealing surfaces must be cleaned; all O-rings must be checked and changed if necessary.
Adhesive substance (e.g. Loctite) must be applied on all bolt joints. All bolts must be tightened with a torque
wrench as specified in the table below.
