INTRODUCTION
Heating or cooling of parts installed with interference
• In the case of bearings, it is a good practice to heat them
for their installation. The expansion of the heated parts
reduces the force needed for installation, facilitating the
procedure and reducing the chance of damage to them.
• The heating should never be done under the action of
direct fire on the parts. Use oil heated at 80 to 90 0 C
or heating by electrical induction see figure.
• On the other hand, tapered bearing shafts and cups can
be cooled to reduce its diameter, also facilitating their
installation.
• Cooling can be done in freezers or with ice (dry or reg-
ular).

GENERAL RECOMMENDATIONS
ASSEMBLY SIDE
• Several components of the machine have parts whose
assembly side must be observed.
• In the row units, such components have a marking, in-
dicating it should be installed on the right side (from the
point of view of who is behind the machine). See ex-
amples in the figure, indicated by the arrows.

tions, the standard factory installation is from left to right.
