Hydraulic system

Postby Rusty fender » Mon Jan 28, 2019 12:34 am

I just rebuilt the hydraulic reservoir on my super A. The lift arms are going up fast but not going down very fast at all. What would the problem be?

Or is this normal. It seems to me before the rebuild they moved going down as fast as they did going up

I've been doing a lot of reading about the hydraulics on my Cub and I assume the super A is similar.

It's set up to restrict fluid exit from the lift side of the cylinder. The idea is to keep it from dropping fast due to implement weight. I suppose it's possible you actually repaired something during your rebuild.

I'd put an implement on it and see what it does. I know "down" on my Cub really labors the engine if there isn't any implement weight.

I was thinking the same thing. Probably repaired something that was letting them go down to fast.
