Hey all,

The hoist on my 1950 1.5 ton dump has gotten slow as it gets to the top, and sometimes you can hear the pump cavitating.

So, I'm thinking I need to add some hydraulic fluid. Got the bed up and securely propped. Then excavated all the gunk to find a fill plug ... with no luck.

Where in the heck do you add the oil? The only fill plugs I see seem too low.

Sorry for the silly question...

Thanks for any advice...
