you should have power beyond orbitrol and not run your orbitrol return as pressure for hyd.b

power beyond... elaborate please....

its extra port in the orbitrol to run accesories like hydro boost.

you dont want pressure in the orbitrol return port. image this your steering takes whiile turning 1000psi and youadd brake and hydro boost takes 1000psi too. prssure in the steering is 0

tought you had orbitrol before hydro boost but seems you have it correct way. orbitrols do make hissing sound when its streered. its still hydraulic valve with small internal ports

They do some but ive had at least 15 full hydraulic steering crawlers over the past 12 years and never had one sound like this.

Usually they hiss some at full lock on either side. This one does that as normal when the front end is on jack stands and there is no pressure on the front tires. The sound goes away except at full lock.
Then, if you set it back on the ground and steer a few times it comes back the whole stroke....

does it have built in pressure relief valve. maybe its set too low

it doesnt have one "in-line" ... built it im not sure about

How is the cooler mounted and plumbed. Both lines out the top? Lines out the side? Wondering if there is air getting trapped or something weird.
Hot line from the orbital to the bottom of the cooler and cool line from the cooler back to the reservoir works best.
Also returning both return lines (hydroboost and cooler) to the top reservoir would help keep any air towards the top or cap of the reservoir so it can be dispersed from the fluid vrs near the pump suction and getting recycled into the system. Getting the returns below the fluid level is best too. Think of pissing into the water vrs you **** being underwater.

Currently there is no cooler....yet. I had planned on plumbing one in when I re did the lines

if it has its located under the allen plug in the face where your steering colum bolts.

does the back plate have id numbers?

I fixed my steering issues with hydroboost. It was really easy.

Step 1: Remove pile of **** hydroboost from buggy
Step 2: Throw in garbage
Step 3: Hook everything back up
Step 4: Drink a 12 pack and wonder why you ever wasted your time with hydroboost in the first place

Conclusion: **** hydroboost.

BTW, french dude loves it, thanks man !

Patrick's buggy has hydroboost and it works awesome. Plumbed like the PSC diagram.

Good ideas for reservoir design :

Glad it works for someone at least

This side.. I'll see if I can read it

The hydrobooster will freeflow until the pedal is pressed. Make sure you have freeplay and not slightly preloaded. It should be the first thing behind the pump as per the diagram. You could have a closed center orbital, in that case, throw it in the trash and order an open center type orbital. Closed center type orbital is a deadhead type valve, won't flow fluid to return unless steering. Peek in the ressy and see if the fluid is circulating when running..
