Loader ford 3550 skip loader hydraulic fill point ?

[dscoffin]

HI, new to the site

I just bought an older ford 3550 skip loader at an auction, it came with a full set of opp., and service manuals. I know this must sound really dump but I can't seem to find the hydraulic fill and or level check point for the skip loader portion. I know the reservoir is built into the skip loader frame itself and I see what I think is a vent on top of the left hand vertical support post. I removed the vent but it is only a .25 hole and no dipstick and I can't find any reference in any of the manuals. ?????

Thanks

Hole should be more like 3/4" NPT. Fill to 12" below vent fitting.

That was it, took about 3 gallons to bring to up to 12".
Thanks for the help
