2006 cv713 how to properly check dump bed hydraulic level

[Bubica]

Hey everyone. I'm new to this dump truck and dump trucks in general. I was wondering how to properly check the fluid levels in my hydraulic resivor that sits on top of the frame between the cab and the lift cylinder. There is no dip stick or window on the tank. Any help is appreciated. I also apologize if this is the wrong thread I'm posting on I'm new on this forum.

depending on the manufacturer of the body, but for a tank on frame between cab and body there should be a plastic or glass tube on front of the tank.

 but basically put, if the piston goes all the way up without chatter there is enough oil in the tank. if you put too much in the tank, it will blow out the vent when body is lowered all the way down. 

 when i add oil to a low system, i add one gallon at a time until piston chatter goes away and body goes all the way up. then add 1 more gallon.

Its tough when the tank is hidden with the body down. I have over filled them a few times and made a mess. I like what tjc suggests.

Welcome to BMT...Any dump trucks Iv ever drove had a sight tube on the side of the tank.You could clean off the tank around the filler cap and open it then dip it with a clean stick or small metal bar.It should not be full to the top but close.As the guys said If its over full it will dump out some oil....messy!!!
