Yes. I’m going to replace the current HCV with a new one. The new HCV will have a longer arm.
My goal is to achieve +-50° of HCV arm angle to mainly improve the exhaust rate of the valve and hopefully stop the front of the bus from having more air in the bags and negatively impacting the steering alignment.
It’s entirely possible the current HCV was damaged when the tech welded the arm to the valve. Simply replacing the valve might solve the problem.
Nonetheless, I believe that a combination of a longer sway bar arm will improve the functionality.
Today I measured the total throw of the sway arm from full down to max up, it only moves 2 1/6” at the center of the mounting bolt.
Ultimately I’d like to relocate the HCV to the left steer axle and set it up similar to the drive axle HCVs.
I guess you can say I’m experimenting.
