GENERAL INSTRUCTIONS
IMPORTANT NOTICE
All maintenance and repair interventions listed in this Manual must be performed exclusively by the Service
Network of the Manufacturer, complying strictly with the indications herein and using, when required, the
prescribed special tools.
Whoeverperforms serviceoperations describedherein without complyingstrictly withthe instructionsbecomes
solely responsible for any consequential damage that could occur.
ADJUSTING SHIMS
For each adjustment select the adjusting shims, measuring them one by one with a micrometer and adding to
gether subsequently, the values measured. Do not rely on the measurement of the entire pack, that could be
wrong, or the nominal value indicated on each ring.
SEALS FOR ROTATING SHAFTS
For correct installation of the seals for rotating shafts, please comply with the following precautions:
-- prior to installation, keep the seals soaking for at least half an hour in the same oil they are going to seal;
-- clean thoroughly the shaft and make sure that its working face is undamaged;
-- direct the sealing lip toward the fluid; in the event the lip is of the hydro dynamic type, the grooves must be
directedsothat, in relationtotherotating directionof theshaft, theytend to returnthe fluidtoward the inside
of the sealing device;
-- smear thesealinglipwithafilmof lubricant(oiltobepreferredtogrease)and fillwithgreasethegapbetween
sealing lip and dust lip in twin lip seals;
-- insert the seal in its seat, pressing it with a punch with a flat face; never strike it with a hammer or mallet;
-- when pressing in the seal, make sure that it is inserted perpendicularly in relation to the seat and, once in
position, make sure that, when required, it contacts the shoulder;
-- to prevent the sealing lip of the seal being damaged by the shaft, insert appropriate protection during the
installation of the two parts.

SELAING COMPOUNDS
Mating surface marked X must be smeared with a sealing compound recommended by the Manufacturer or an
adequate equivalent.
Prior to applying the compound, prepare the surfaces in the following manner:
-- remove all possible scaling with a metal brush;
-- degrease the surfaces thoroughly using the degreesing agent recommended by the Manufacturer or an
adequate equivalent.
BEARINGS
When installing bearings, it is recommended to:
-- warm them up to 80° –90°C (176 – 194 °F) before installing them on the relevant shafts;
-- cool them down before inserting them in the relevant seats with an outer fitting.
SPLIT PINS
When installing split pins, make sure that the cut is pointing in the direction of the load on the pin.
On the other hand, spiral elastic pins do not require any installation orientation.
