Yale GCO40BCNNAT 077P:
Bleeding mast hydraulic ram

Hi!
I have an old Yale 1969 I believe with low hours that I picked up for not much and it runs/works great except there seems to be some air trapped in the main ram.If the truck is left forks raised for 4-5 hours with no load and you step on the forks they wil sink a couple inches.This does not happen when machine is running or loaded. If there is a way to bleed the system how might I go about it.
There appears to be what looks like a bleed nipple on the top of the main ram.
Thank you,
sam

Mrfixit,
Thank you very much.
Bleeding mast ram worked perfectly as you described.Now I have to figure why the brakes are so terrible.Replaced right wheel cylinder because was leaking,bled system with no real change.Must be the master cyl I figure.
Thanks again,

Right in the center on top of the ram is the bleeder. Make sure you have the forks down all the way before opening or you will have a geyser. Open it and place a rag up there, start it and gently pull the lift lever until all the air is out.
