ABSTRACT:
Conventionally, air brake cam clearance is difficult to check due to inaccessibility and the force necessary to rotate the cam to check for the required clearance. The present device engages around the end of the cam lever both front and back and gives sufficient leverage to rotate the cam without any danger of slippage occurring. A wrench is formed on the opposite end of the tool and may be used for adjusting the clearance if necessary.
