Oliver super 88 hydraulics

Hello,

I was wondering - did Oliver ever offer a factory built, add on reservoir to increase hydraulic fluid capacity on S77 - S88 or 770 -880 ? I know the big pipe plug is there to
plumb into the side of the hydralectric unit. I've seen many kinds of reservoir add ons - but they all appear to be home made.

Thanks !

ours had a hose that clamped on the fill/dipstick port to a tank mounted on the left fender, seemed factory but I'm not sure.

The factory may have made a add on unit to the reservoir, but I have never seen one. We have made several over the years for a loader tractor. For a loader the add on needs to be plumbed to the top of the filler neck and the bottom. This is because when the loader goes down oil returns to fast in to the hydraulic to flow across the bottom port. The breather should be on the add on reservoir.

OK - Thanks Centerplate and Chucks77. I hadn't thought about the oil not being able to get back through the bottom port fast enough ! Did you have any trouble with oil leaking around the levers and rubber boots on top of the hydralectric ?
