Need to know if there are fluid levels (gear lube or hydraulic fluid) one needs to check on the pump whcih drives the ram to lift the bed? All I am able to see is a breather cap on top of this box-like thing that the PTO is connected to. Should I see fluid in the opening where the breather cap is? or do I look elsewhere on this box? I do not know what type this is, I only know that his is on a 47' chev, 1&1/2 or 2 ton dump. The unit does work but has alot of dirt an grime indicating leaks.
