SAFETY INFORMATION

Hydraulics Safety

• Inspect all hydraulic line connectors and ttings. Make

sure all hydraulic hoses and lines are in good condition

before applying pressure to the system.

• Keep body and hands away from pin hole leaks or

nozzles that eject high pressure hydraulic uid. Use

cardboard or paper to nd hydraulic leaks. Hydraulic

uid escaping under pressure can penetrate the skin

and cause injury. Fluid accidentally injected into the

skin must be surgically removed within a few hours by a

doctor or gangrene may occur.

• Before disconnecting or performing any work on the

hydraulic system, lower the loader arm/attachment to the

ground and stop the engine so all pressure is relieved.

• Be sure you understand a service procedure before

working on the machine.

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 specified in the 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 the

service manual. The following factors shall be

considered when applying torque: cleanliness of the

fastener, use of a thread sealant (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 specific

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

performed 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, 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.
