Oil control
The oil is controlled by removing the upper oil plug A. The oil has to be clean and the level has to reach the plug
hole. Oil type see spare parts list. If the oil is dirty it has to be exchanged.
A. Upper oil plug
B. Lower oil plug
C. Grease nipple
D. Inspection plug
The oil is drained off by removing the plug pos. B. If the oil is dirty, seal and wear bushes must be checked for
wear and contamination. Oil is filled at oil plug pos. A.
Lubricate the outer sealing system with grease (see spare parts list). This takes place through the grease
nipple, pos. C, 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 controlled in the following way: Remove the inspection plug, pos. D, beneath the
motor. Any seepage of oil or liquid can be seen immediately.
In case of abnormal seepage 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 POPR-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.
