 Torque Arm Installation

Flange Mount (Banjo) Torque Arm

Torque Arm  

Bolt 

(Customer 

Supplied)

2

Place washer and rubber bushing on bolt .

Insert torque arm bolt (supplied by customer) through mounting tab on Flange 
Mount (Banjo) type torque arm .

Make sure bolt is parallel to Banjo type torque arm side surface when fully 

installed

3 

Follow these steps to attach the torque arm to  
mounting structure or mounting angle  
bracket (customer supplied):

•  Verify that the mounting structure or 

 

mounting angle bracket hole is the  
correct diameter (refer to Table 5) .

•  Place rubber bushing and mounting 

 

angle bracket on bolt .

•  Ensure the bolt passes through mounting 

 

structure or mounting angle bracket hole .

•  Place remaining bushing, washer and 

 

two nuts on the bolt .

Do not over-tighten nuts . Tighten  

to point where rubber bushings can 

 

still be hand rotated .

4

Confirm that the rubber bushings can still be rotated by hand . This indicates the 
bushing has not been over tightened .

Compressed bushings will not allow the bushings to properly absorb the 
loads of the shaft mounted gearbox . This can lead to premature failure .

Mounting Angle Bracket must be secured to the machine structure .

Rubber  

Bushing

Washer

When installed, 

bolt must be 

parallel to this 

surface

Note:

 

[1] 

Bolt class should be greater or equal to 

ISO/JIS Class 8 .8 .  Application with multiple start/
stops and/or shock loading should use ISO/JIS 
10 .9 at a minimum . 

During full rotation of driven shaft, there must be no 

metal-to-metal contact between mounting angle bracket 

and torque arm .

5

Confirm the mounting angle bracket

 

does not interfere with the torque 

arm . 

There should be no metal-to-metal 

contact between the two during a 
complete revolution of the driven 
equipment .

Metal-to-Metal contact 

between these two 

components may lead to 

catastrophic failure of the 

reducer/gearmotor .

Bushings are free to rotate by hand
