Oil control
The oil is 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 table. If the oil is dirty
it has to be exchanged.
A. Upper oil plug, oil chamber
B. Lower oil plug, oil chamber
C. Lower oil plug, gear
D. Inspection screw
F. Stop screw/grease nipple
G. Upper oil plug, gear
The oil is drained off by removing the plugs pos. B and pos. C (ms100-180) or pos. C (ms80-90). If the oil is
dirty, seal and wear bushes must be checked for wear and contamination. During filling of oil through oil plug
pos. A (ms100-180) the oil plug pos. G must be removed to allow bleeding of the gear. For ms80-90 oil is filled
at oil plug pos. G on the gear.
Grease lubricates the outer sealing system (see spare part list). This takes place by removing the stop screw
pos. F placed right behind the propeller hub and then lubricate through the grease nipple. For ms80 and ms90
the grease nipple is fixed. Prior to reinstallation the propeller fill up the hub with grease.
The motor casing must be checked 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 it is necessary to dry up the motor windings, contact a special workshop.
Equipment
The equipment should be checked for wear and corrosion. The winch is to be grease lubricated. Check brake
and lock. Retighten screws. If the screws are loose remove them and lubricate with an adhesive substance (e.g.
Loctite) prior to reinstallation.
Disassembling/assembling
A major repair should take place at a special workshop.
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 are tightened with a tightening
torque acc. to the table below.
