Tractor protection valve

Recommended Posts

I have a 1960 B61 Mack.  It is still all original.  Old tractor protection valve is bad.  Have not been able to find an original replacement.  Was able to find a valve that is similar.  Installed new valve, but now back brake chambers have no movement when engaged or disengaged.  My Dad changed out the spring brakes to lock down brakes a few years ago.  I am trying to use the original Mack air supply switch in the cab to engage the brakes.  The original valve supplied the brake chambers with air supply.  I have everything installed the same way, but I am wondering if this tractor protection valve might not work with the original equipment.  Would be willing to change to a different valve if needed.  Any help would be greatly appreciated.
