A hydraulic reservoir comprising:
- a plastic container body defining a container cavity, the container body having projections extending inwardly from an outer wall of the container body and a manway access for accessing the container cavity;
- and
- an insertable baffle positioned in the container cavity adjacent the projections of the container body, wherein the baffle is inserted into the container cavity through the manway access and is held in position in the container cavity, at least in part, by the projections of the container body.
A hydraulic reservoir comprising:
- an integral, one-piece plastic container body;
- a container cavity formed by the container body for holding hydraulic fluid, the hydraulic fluid defining a normal fluid level line within the container cavity;
- a manway access formed in the container body providing access to the container cavity;
- at least one baffle holding member formed in the container body;
- an insertable baffle positioned in the container cavity adjacent the at least one baffle holding member, the baffle positioned in the container cavity through the manway access;
- at least one return port in the container body in fluid communication with the container cavity;
- and
- at least one outlet port positioned near a bottom of the container body in fluid communication with the container cavity.
