The shifting gear on Type 25 buses is a rather complex unit in which many different parts are used. The transmission in the gear box will be executed between the shift arm and the gear box with a ball that is handled by a hollow lever. This transmission is lubricated with grease and this connection will be protected on its turn against dust and moisture by means of a rubber boot. In case this boot is torn it does no longer fulfill its protecting function and transmission will be damaged by dirt and moisture. The rubber boot is delivered each from stock.
