Synchronizing two cylinders

Great thing about these puppies is you can intensify hyd pressure if needed from a low pressure system

Just run output from hyd pump through flow divider, then run one output to tank, the other output in to the hyd system and VOILA, twice the pressure (although half the flow)

Be careful with a flow divider. Due to tolerances and differences in leakage, they WILL slowly get out of sync. In a well designed circuit, one or more additional valves are needed to re-sync the cylinders. Additionally in many cases with some small error, a flow divider can generate excessively high pressures, so additional relief valves are also generally recommended. Bottom line is that it can get complicated quickly with a flow divider.

tech man is correct you're complicating your circuit and not solving your problem

my question now is do flow dividers work in reverse too? as in to combine equally 2 input flows? if not will they allow flow in the opposite direction at all?

You can get ones that do and ones that don't. Mine were supposed to be in today but were a day late shipping, I'll know by tomorrow afternoon how things are working.

the reason I was asking was that if they do then you would only need one.

all of the ones i know about require two for this function however sun hydraulics makes a valve to do this with eliminating the need for the the two gerotor flow dividers. if you go with the gerotor you can still "t" in the inlets and use the outlets to cross connect the cylinders keeping the steering turns even

It's almost always on level, relatively smooth ground and speeds are 10 mph tops. Most of the steering will be minor corrective steering just to keep the sled straight.

Keep it simple and just use two valves. Two handles close together, plumbed so forward on both, with one hand, is left turn, for example. If the wheels don't look quite right, then adjust one of the valves.

Well everything is working like it should after the flow dividers were installed today. The cylinders work together so my steering appears to be up and running. Thanks to everyone who helped with this.

When I posted earlier, I had a completely different idea of what you were trying to do. I think i got it now, but would you mind posting some pictures? It sounds like something that I may be doing to my Case 930.

I'll try to remember to snap some pictures tomorrow. I would have today but I need to get the hoses tied back up and the gallons of fluid laying everywhere cleaned up.
