    Volvo thumb trouble

    I’m not sure if this will be helpful or not but I’ll mention it anyway.This morning it’s rainy so I got curious and hooked the thumb up and actuated it. It opens snd closes fine it’s just a little slow on the close from the lack of pressure. Also the bucket can push it back effortlessly since...

    Volvo thumb trouble

    Volvo thumb trouble

    Yes that is correct. The thumb is brand new and this machine has never had one. I’m controlling the shear function with the joystick buttons. Also I do have the three way divider your talking about. I can get a picture of it in a couple minutes.

    Volvo thumb trouble

    I’ve been trying to set the relief pressure for my thumb on my Volvo 240b excavator. No matter how I adjust the two stage relief I can’t get the pressure over 1000psi and it will not hold any pressure after I let off the button. I don’t know if I have a broken part or am missing...

    Volvo help needed - setting pressure on optional hydraulics for thumb

    I’ve been trying to go the same thing on my Volvo 240b but I seem to be having issues. I got the right side of the stick hood to go but when I got to the left it won’t go over 1000 psi and will not hold pressure as soon as I let off the button. Does anyone have any advice? I’ve tried adjusting...
