Bearing Replacement; Spare Parts - ITALVIBRAS GIORGIO SILINGARDI CDX Serie Guia Tecnica

All maintenance, repair and overhaul operations carried out by
a third part and not by ITALVIBRAS void warranty.

5.0 BEARING REPLACEMENT

In order to assure the belonging category of the CDX electric
vibrator the bearings condition is essential.
Consequently the bearings have to be maintain in a good condition
and , in case of anomalous noise, the bearings have to be
substituted.
5.0.1 Bearing replacement frame sizes 10-20-30
These vibrators have ball and shielded bearings and bearings that
are pre-lubricated for life.
Remove the power supply from the vibrator, disassemble from the
machine, remove the weight covers, the OR seals and disassemble
the eccentric weightss.
Disassemble the 2 (two) Seeger rings mounted on the flanges
near to the bearings. For these vibrators the flanges form a unique
motor group unit with the casing and cannot be disassembled.
Push the shaft from one side using an adequate force until it exits
from the opposite side (Fig.21, page 9). The shaft will drag at least
one bearing while one remains in its flange.
By exercising axial pressure, remove the bearing from the shaft and
the one remaining in the flange.
Check the bearing seat in the flange. If it is worn the entire motor
unit must be replaced. The flanges are fixed tightly to the casing and
cannot be replaced.
Mount the first bearing in a flange paying attention that it remains
just beyond the seat of the Seeger ring, then mount the Seeger
ring.Pressure-mount the second bearing onto the shaft from the
side where the bearing is blocked (ATTENTION: the shaft is not
symmetrical, from one side the bearing is blocked in a radial
manner, from the other side the bearing is free) (Fig.22, page 9).
Insert the shaft into the motor unit from the correct side (Fig.23,
page 9) and press until the shaft enters its final position, mount the
second Seeger ring.
Re-mount the masse, seals and weight covers (Fig.20, page 8).
Control the state of the seals during this operation and replace
them if necessary.Turn the shaft manually to ensure that it turns
freely without axial play.
5.0.2 Bearing replacement frame sizes 35-40-50-60-70-80
These vibrators have roller bearings, already lubricated in the
factory by ITALVIBRAS.
Remove the power supply from the vibrator, disassemble it from
the machine, remove the weight covers, the OR seals and
disassemble the eccentric weights.
Remove the flanges from the casing using the threaded extraction
holes (Fig. 24, page 9). Remove the shaft and the second flange.
Remove the bearing cover and slide the bearing out through the
extraction holes (Fig. 25, page 9). Using the necessary equipment
on the bench, replace the bearings and the specific hold rings.
Check the bearing seat in the flange. If worn replace the flange. On
re-mounting the bearings pay attention that they rest correctly on
the stroke of their seat.
Half fill the chamber between the sealing ring and the bearing with
grease.
Apply the new grease in the quantity prescribed in the «Technical
Features» table (pages 87-90) spreading deeply inside the bearing
applying pressure to allow penetration of the grease into the rolling
parts.
Once the operation has been carried out , re-mount by performing
the operations in the opposite order taking care to maintain
perfect orthogonality of the flange with respect to the casing (Fig.
20, page 8). Pay attention that the seals are correctly positioned
in their seats. Control the state of the seals during this operation
and replace them if necessary.
ENGLISH
Turn the shaft manually and ensure that it has axial play between
0.5 and 1.5 mm.
ATTENTION: Every time the afore-mentioned maintenance
operations are carried out it is recommended that all
disassembled screws and spring washers are replaced and
that the screws are tightened using a dynamometric wrench.
5.1 LUBRICATION
All bearings are correctly lubricated on mounting the vibrator.
All ITALVIBRAS vibrators are realised to use the "FOR LIFE",
lubrication system and therefore do not require periodical
lubrication.
Only for heavy duty, as for example 24 hour service with high
environmental temperatures, starting from frame size 40 periodical
re-lubrication of the bearings is recommended, using the two
external greasers (1/8" NPT) with the following type of grease:
- KLUEBER ISOFLEX TOPAS NB 52.
Failure to use grease type Klueber Isoflex Topas NB 52 shall void
the guarantee with which the motor-driven vibrator is covered.
Use of a different grease could damage the electric vibrator.
Approximately, on average, the frequency of re-lubrication can be
included between 1000 and 5000 hours and depends on the
operative conditions and the type of vibrator, therefore it can be
lower or higher than the indicated values. The quantity of grease
to be introduced on periodical lubrication is indicated in the table
on page 87.
It is advised to contact ITALVIBRAS for particular uses which is at
complete disposal to advise the client on the best lubrication
possible for the specific use.
Never mix greases even if they have similar features. Excessive
quantity of grease causes increased heating of the bearings and
consequent anomalous current absorption.
Respect the ecological laws in force in the country in which the
equipment is used, relative to use and disposal of products used
for cleaning and maintenance of the vibrator. Always comply
with recommendations of the manufacturer of these products.
If the machine must be demolished, comply with the anti-pollution
regulations envisioned in the country of use.
Remember that the Manufacturer is always available for any
type of assistance and spare parts.

5.2 SPARE PARTS

On requesting spare parts always state:
- Type of vibrator (TYPE detectable from the identification plate).
- Serial number (SERIAL NO. detectable from the identification
plate).
- Power supply voltage and frequency (VOLT and HZ detectable
from the identification plate).
- Spare part number (detectable from the spare part table starting
from page 91) and desired quantity.
- Exact destination address of the goods and means of delivery.
ITALVIBRAS declines any liability for incorrect forwarding due to
incomplete or confused requests.
ITALVIBRAS declines any liability for maintenance operations
carried out by a third part company, even if usingoriginal spare
parts.
