Hi guys i have a 1957 f600 in really good shape everything original and im in the process of restoring it and it has a heil hydraulic hoist well the hydraulic pump was leaking fluid so i thought i would fill it up but i couldnt find a resivor i am not sure how to fill this system i am replacing the hydraulic lines those were original to the truck and also every thing has a number on it besides the cylinder, the pump does have a number and i have the brass plate with the hoist model and serial number attached to the hoist itself i need to find a rebuild kit if possible if anone can help thank you if i am posting this on a wrong part of the site i am sorry haha

Thanks

 

Good questions. The pump most likely seals. I think I would send it out
cause there is a million pumps out there and the hydraulic guys know
what their doing. Filling the system, most likely or common, its in the
cylinder. does it lift up at all? If not, Im afraid you will have to lift the
body up with a loader or something and pour hyd fluid in the top theres
a plug, fill with the pump running. Be prepaired, pour slowly or you will
get soaked. Always prop the body with 4x4's while under there. After
awhile you will hear the pump whinning add more fluid. Remove props
and unchain loader and work it up and down adding fluid till it goes all
the way up. be prepaired to use about 5 gal. depending.
does this help?

 

I personally have never filled a lift system of this nature through the cylinder. There should be some kind of reservior, and a cap that looks like a breather typically. I have seen a few that had a pipe plug.

I have seen the pump (and currently have this arrangement) inside the reservior, and also have seen the pump separate from the reservior.

 

My fontain hoist uses cyl for resivour. Top is tank, lower end cyl.

 

Thanks for replying, and i currently have the truck apart i'm restoring it and i have everything off of the truck but will be putting it back on and yes the system worked fine just needed new hoses and the pump fixed but with my pump it does have a plug but it is on the bottom, the cylinder does come apart easily i will be at the shop later if pictures would help thats no problem i wander if i turn the pump upside down to fill it up would work? Because that woluld be the only way to fill it, but the point is i fill it through the pump correct? That was my wonder was to fill the cylinder or the pump, thank you for your advice thanks again for replying

 

You do not fill it thru the pump.

As mentioned, you either have a reservoir built in as part of the cylinder, which is very common on 2-5 yard size box hydraulics or a separate reservoir that has a breather cap on it.

Either way, nothing to fill on the pump itself.
