4.While checking the hydraulic oil level, also check the condition of the hydraulic oil in the seal cavity . Block the opening with a finger and roll pump to one side to drain oil into a small transparent container.If oil is cloudy or has water in it, drain oil from pump cavity and replace hydrau- lic oil. Check the seal for wear damage.

5.If oil level is low fill with SAE 10 weight non-detergent hydraulic oil (i.e.ShellTurbo 32 or equivalent). Fill oil cavity 75% to 85% full (allow air space for expansion). See Table 1 for pump oil cavity capacity.
