Installation must be performed by qualified personnel. Allow
sufficient room around the geared motor for plugs (or vessel)
accessibility:
- 200 mm : G1/4’’ plug for Mub 31 to 35
- 500 mm : G3/4’’ dipstick for Mub 36 to 38.
H
1/4 H min.
Gearbox:
For the installation of Manubloc 3000 gearbox, follow the
“Recommendations” chapter in the general manual.
If the gearbox is fitted with a MU universal mounting with a stiff
coupling by key, we recommend the application of a lithium
paste (molykote TP42 or equal) on the motor shaft.
Motor:
For connection of the complete drive system (with brake),
follow the instructions of corresponding maintenance delivered
with the goods in the parcel.

1.2 - Torque point
Manubloc torque must be absorbed by an appropriate torque
arm (not supplied).
Too much play can produce dangerous shocks during reverse
operation or gear changes, flexible mountings are therefore
recommended: dampers in stressed rubber (Silentbloc type).
The flat end of the housing has cross tapping for this type of
mounting according to the outline diagram. The other parts are
not supplied by Leroy-Somer.

1.3 - Hollow shaft
1 -
Check that the cylindrical shaft has been machined in
accordance with standard NF - E 22 - 175, with a slide fit: g6,
(the hub is: H7).
2 -
Check that the key is standard and the shaft is the minimum
length tapped at the end.
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 Mub 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.
