2 - OPTIONS MOUNTING

2.1 - Shrink-disc

2.1.1 - Mounting

Remove all grease from shaft and hollow shaft bore.
1 - Lightly oil the seating of the shrink-disc on the hollow shaft.
2 - Draw shrink-disc onto hollow shaft. Slide shaft and hollow
shaft into one another.
3 - Tighten the shrink disc screws, increasing the torque very
progressively to tightening torque indicated in the chart bellow.
It is normal that each screw must be tightened several times
until the torque is obtained.

Do not tighten "cross-shaped" but "in one rotation", starting at

Dismantling
1 - Part-release the clamping screws evenly in stages in order
to avoid any tilting of the clamping flanges whilst taking great
care for safety reasons that the clamping screws are not
completely released from the thread bore as the pretensions in
the shrink-disc could cause the discs to jump apart.
2 - Draw the shrink-disc off the hollow shaft, and if applicable,
clean oxidizing on shaft and hollow shaft bore.

3 - MAINTENANCE

Control after commissioning (50 hours of operation).
Check tightening of fastening screws and belt tensioning if
applicable.
Preventive maintenance visit
- Check regularly that the recommendations concerning me-
chanical and electrical installation are still complied with.
- Lubrication : refer to corresponding documents.
- If the gearbox is fitted with a breather plug, make sure that the
vent hole of the plug is not obstructed.
- Inspect the seals.
- Clean the ventilation louvres of the motor.
- Lubricate the bearings of the motors fitted with grease nipples.
- Control the air gap of brake motors.

4 - LUBRICATION

For operation in ambient temperature between -10°C and
+40°C, Manubloc 3000 reducer is shipped, as standard, with
mineral Extreme Pressure oil: EP ISO VG 220.
For oil-lubricated gearboxes, check oil level and eventually
top up if necessary
From -30°C to +60°C: synthetic oil PAO ISO VG 150.
From -30°C to -10°C: synthetic oil PAO ISO VG 32.
From -30°C to +60°C and for use in the food industry: synthetic
oil PAO H1 ISO VG 150.
You must use an oil of the recommended type.
Polyglycol lubricants cannot be mixed with mineral or synthetic
lubricants of a different type.

Oil capacities
The oil capacities shown in table (see § 4) are approximative
1
values and should be used only as reference in determining
4
how much oil to provide. The proper oil levels can only be
1
determined by:
- Mub 31 to 35: plug: filling the reducer to the level of the plug.
- Mub 36 to 38: dipstick (J): adjust oil level between the 2
marks (up/down)
Adjust oil level.
Inspect the seals.
Drain and refill mineral oil.
Change the seals.
Change the grease of regreasable
bearings.
Drain and refill synthetic oil.
Change the seals.
Change the grease of regreasable
bearings.
