A hydraulic monitor barrel is protected from falling debris by attaching to the monitor housing a pair of spaced vertically positioned plates, so that the monitor barrel can moved freely between the plates and yet be protected by the plates from any debris which should fall on the monitor. In addition, the bearing of the monitor is protected by providing a yieldable coupling between the housing and the bearing, so that when vertical forces are applied to the housing, the housing settles against the base of the monitor and transfers the forces thereby from the vertical plates to the monitor base, rather than through the monitor bearing.
