Torque Specifications
Recommended fastener torque values are listed in the
following tables. For critical applications, as determined
by Toro, either the recommended torque or a torque that
is unique to the application is clearly identified and spe-
cified in this Service Manual.
These Torque Specifications for the installation and
tightening of fasteners shall apply to all fasteners which
do not have a specific requirement identified in this Ser-
vice Manual. The following factors shall be considered
when applying torque: cleanliness of the fastener, use
of a thread sealant (e.g. Loctite), degree of lubrication
on the fastener, presence of a prevailing torque feature
(e.g. Nylock nut), hardness of the surface underneath
the fastener’s head or similar condition which affects the
installation.
As noted in the following tables, torque values should be
reduced by 25% for lubricated fasteners to achieve
the similar stress as a dry fastener. Torque values may
also have to be reduced when the fastener is threaded
into aluminum or brass. The specific torque value
should be determined based on the aluminum or brass
material strength, fastener size, length of thread en-
gagement, etc.
The standard method of verifying torque shall be per-
formed by marking a line on the fastener (head or nut)
and mating part, then back off fastener 1/4 of a turn.
Measure the torque required to tighten the fastener until
the lines match up.
