While the machine is operating, the hydraulic oil expands due to temperature. The oil pressure in the stabilizer cylinder rod end increases. The cylinder head may loosen due to the pressure. The new lock valves feature thermal relief in order to reduce this problem in the 106-6249 Stabilizer Lines. See Table 1 for the changes. See Table 3.
Connect the smaller port size of the lock valve to the hose on the stabilizer cylinder rod end.
