Checking the diameter of the wheels

 

The running surfaces of the wheels become worn during operation. This reduces the diameter of the wheels.

 

Exposing the wheel

Only for size 200 to 420

 

 

Buffer plate

Self-locking nut

Plastic washer

Measuring the diameter

*   Measure the diameter of the wheel at multiple points over the width of the wheel.

 

*   The diameter may not be smaller than is specified in the table.

If the diameter is smaller, the wheel must be replaced. See Disassembling the powered wheel.
