SECTION 01 - MAINTENANCE

place the sealing lip towards the fluid. In case of a
hydrodynamic lip, consider the shaft rotation direc-
tion and orient grooves in order that they deviate
the fluid towards the inner side of the seal;

coat the sealing lip with a thin layer of lubricant (oil
rather than grease) and fill with grease the gap be-
tween the sealing lip and the dust lip of double lip
seals;

insert the seal into its seat and press it down using
a flat punch. Do not tap the seal with a hammer or
a drift;

take care to insert the seal perpendicularly to its
seat while you are pressing it. Once the seal is set-
tled, ensure that it contacts the thrust element if re-
quired;

to prevent damaging the sealing lip against the
shaft, place a suitable protection during installa-
tion.

O-RINGS

Lubricate the O-rings before inserting them into their
seats. This will prevent the O-rings from rolling over
and twisting during mounting which will jeopardize
sealing.

BEARINGS

It is advisable to heat the bearings to 80 to 90 °C be-
fore mounting them on their shafts and cool them
down before inserting them into their seats with ex-
ternal tapping.

SPRING PINS

When mounting split socket spring pins, ensure that
the pin notch is oriented in the direction of the effort
to stress the pin.
Spiral spring pins should not be oriented during in-
stallation.

HARDWARE TORQUE VALUES

Check the tightness of hardware periodically. Use
the following charts to determine the correct torque
when checking, adjusting or replacing hardware on

IMPORTANT:

Torque values listed are for general

use only. Make sure fastener threads are clean and
not damaged.

NOTE:

a torque wrench is necessary to properly

torque hardware.
