Hello,

I've got a H2 140" limo and used to run stock wheels and tires.
Now i got 22" wheel with road tires.
When the car is not moving it's not possible to turn the steering wheel (only a couple of degrees left and right)
People (and the internet) tell me its the weight of the car thats causing the problem. Ok, but what can i do to fix it?

I already bolted on a new pump (acdelco reman.) but no difference.

Is there a valve in the Hydroboost that is keeping the flow away from the steering box? (if so can i tweak this?)

I also thought of bolting on an extra pump.
This can be connected parallel to the original pump (pressure tube going to hydroboost) but is there is a valve issue, this wont work...)

Or can u bolt this pump on and connect it straight to the steering box.

I also have a H3 140" limo with 20" wheels and there is no steering issue.

I would really appreciate your feedback.
Sorry for my English, as i come from Belgium, Europe.

 

Je engels is bijna net zo goed als mijn nederlands haha

Those 22 inchers, how wide are they?
Previously I had 37 inchers on mine and they were 355mm wide. I had issues with the hydrobooster. It would sometimes cause the steering wheel not wanting to move at all. I gues the total weight of the wheel, together with the extra wide footprint would cause too much stress on the hydrobooster
I went back to 35 inch and 325 wide and never had any trouble since.

So yes I think you have a hydro booster overload. Maybe they sell a more beefy one?

Als je hulp nodig hebt in het versturen van onderdelen naar Belgie laat het dan even weten.Ik heb een bedrijf dat daar in specialiseert.

Hey, in het Nederlands is idd makkelijker maar dan verstaat Amerika dat weer niet hé.

The 22" are 355 wide.
The total weight of the limo is to much.
I put the original wheels and tires back on the limo today.
It's better but not completely cured.

I need someone that knows his way around this to tell me if i can connect a pump straight to the steering box. I can try it myself but it will save me a lot of work if it turn out that i need the valve in the hydroboost to regulate the flow and pressure to the box...

Thx in advance.

 

I also have a H2 limo and a H3 limo. The H3 does great but as for the H2, no power steering when not moving
