8.5 120’ Boom Orifice Installation
If the kit is being installed onto a 120’ boom, it is recommended that an orifice
be installed in each wing cylinder accumulator. This is not necessary for
booms without accumulators.
1. Before continuing, make sure the booms are lowered all the way to the bottom of the
cylinder travel.
2. Place one of the o-rings (F10) into the o-ring groove on the inline orifice (F11).
3. Remove the wing accumulator and insert the inline orifice (F11) between the accumulator
and fitting.
4. Reassemble and repeat for the opposite tilt cylinder.
