This cap (or bellows) is not just a piece of rubber. He plays a crucial role:
Anti-contaminant barrier: It prevents track dust, sand and water to enter the body of the pump.
Protection of the axis: If dirt enter here, they mix with fat, creating an abrasive paste that will scratch the piston and destroy your internal seals.
Maintaining the lubricant: It keeps the clean fat inside the mechanism of the thrust rod.
