Never operate an engine in a conned area without
proper ventilation.
Avoid injury from batteries…
Battery acid is poisonous and can cause burns. Avoid
contact with skin, eyes and clothing. Battery gases can
explode. Keep cigarettes, sparks and ames away from
the battery.

Torque Specications
Inch Series bolts and Screws
(A) Grade 1 & 2
(B) Grade 5 (C) Grade 8
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 identied and
specied in the service manual.
These torque specications for the installation and
tightening of fasteners shall apply to all fasteners
which do not have a specic requirement identied
in the service manual. The following factors shall be
consid ered 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, hardness of the surface underneath of
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 specic torque value should
be determined based on the aluminum or brass material
strength, fastener size, length of thread engagement,
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.

Standard Torque for Dry, Zinc Plated & Steel Fasteners (Inch Series)
Standard Torque for Dry, Zinc Plated, and Steel Fasteners (Inch Series)
Note: Reduce torque values listed in the table above
by 25% for lubricated fasteners. Lubricated fasteners
are defined as threads coated with a lubricant such as
oil, graphite, or thread sealant such as Loctite.
Note: Torque values may have to be reduced when
installing fasteners into threaded aluminum or brass.
The specific torque value should be determined based
on the fastener size, the aluminum or base material
strength, length of thread engagement, etc.
Note: The nominal torque values listed above for
Grade 5 and 8 fasteners are based on 75% of the
minimum proof load specified in SAE J429. The
tolerance is approximately ± 10% of the nominal torque
value. Thin height nuts include jam nuts.
