RECOMMENDATIONS
Installation must be performed by qualied personnel. Allow
sufcient room around the geared motor for plugs (or vessel)
accessibility :
- 200 mm : G1/4’’ plug for Ot 31 to 35.
- 500 mm : G3/4’’ dipstick for Ot 36 to 39.
H
1/4 H min.
Gearbox:
For the installation of Orthobloc 3000 gearbox, follow the
“Recommendations” chapter in the general manual.
Motor:
For connection of the complete drive system (with brake),
follow the instructions of corresponding maintenance delivered
with the goods in the parcel.
Gearbox nameplate:
1 - gearbox model and size ;
2 - operating position ;
3 - xing type (S with foot, BS, BDn or SBT…) ;

2 - 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 mech-
anical and electrical installation are still complied with.
- Lubrication : refer to corresponding documents.
- If the gearbox is tted 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 tted with grease nipples.
- Control the air gap of brake motors.
Oil, seals, bearings.
6 months Adjust oil level.
Inspect the seals.
3 years
(or 5 000 h)
Drain and rell mineral oil.
Change the seals.
Change the grease of regreasable
bearings.
5 years
(or 25 000 h)
Drain and rell synthetic oil.
Change the seals.
Change the grease of regreasable
bearings.

- Replace the grease ISO VG 100, NLGI 2, after 12 000 h
(25°C; 1500 min-1)
Storage
period
< 1 year AP can be commissioned without
regreasing.
>1 and <2
years Regrease before commissioning.
2 to 5 years Dismantle AP. Clean it.
Replace the grease completely.
3 - LUBRICATION
For operation in ambiant temperature between -10°C and
+40°C, Orthobloc 3000 reducer is shipped, as standard, with
mineral Extreme Pressure oil : MIN EP ISO VG 220.
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 § 3.2) are appro-ximative
values and should be used only as reference in determining
how much oil to provide. The proper oil levels can only be
determined by :
- Ot 31 to Ot 35 : plug : lling the reducer to the level of the
plug,
- Ot 36 to Ot 39 : dipstick : adjust oil level between the 2
marks (up/down).

4.2.1 - Torque arm mounting
Screw the torque arm (17) on the xing side and machinery by
using screws (195) class 8.8 minimum (according to NFE 27-
005). Centre torque arm. Place the pin.
The screws must be stopped by an anaerobic adhesive (Loctite
Freinlet normal 243 for example). This adhesive must resist
to vibrations and may allow dismounting of torque arm if
necessary.

4.3 - Hollow shaft
1- Check that the cylindrical shaft has been machined in
accordance with standard NF - E 22 - 175, with a slide t: g6,
(the hub is: H7).
2 - Check that the key is standard and the shaft is the minimum
length tapped at the end (O.Z).
3 - Before mounting, degrease all the parts, taking care not to
splash any solvent on the seals.
Use grease (PAO compound) to lubricate any parts in contact,
to avoid corrosion.
Fixing on a shouldered shaft Fixing on an untapped shaft
Mounting
Mounting should be performed as described in the procedure
above, without jolting.
The gearbox is mounted on the machine shaft using a threaded
rod, screwed into the shaft.
By screwing the nut down onto the washer, the shaft is
smoothly inserted into the cylindrical hub.
Dismantling
Use a spanner with a diameter corresponding to the shaft
thread and turn until the shaft comes out.

4.1 - Shrink-disc Ot 3132 to 3933
4.1.1 - Mounting
Remove the cover. 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 diametrically opposed clamping screws by hand
whilst aligning the shrink-disc so that the clamping anges lie
parallel to each other.
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.

Tighteness of shrink disc screws to be controlled
periodically.
Dismantling
1 - Part-release the clamping screws evenly in stages in order
to avoid any tilting of the clamping anges 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.
