The coil is removed by loosening the coil's retaining nut.Note: The new solenoid valve must be tightened to a torque of 50 5 N m (36.88 3.69 lb ft).After you have installed the new solenoid valve, attach the coil to the solenoid valve with the coil's retaining nut.Note: The retaining nut must be tightened to a torque of 13 1.5 N m (9.6 1 lb ft).In order for the new solenoid to function, a new 186-0238 Harness is required to connect the solenoid and the interlock manifold valve to the electronic control systems of the machine. Refer to the above illustration for installation information.Note: Only the following machines will need a new harness: 216 (PIN: 4NZ1-665), 226 (PIN: 5FZ1-1874), 236 (PIN: 4YZ1-1228) and 246 (PIN: 5SZ1-1065).The new electronic solenoid valve requires flash downloading of the new 186-0089 Work Tool Software Group (Auxiliary). Once flash downloading is complete, the new software must be programmed into the Auxiliary Hydraulic Electronic Control Module (ECM). The new software group is obtained from the flash files which are found in the Service Information System (SIS).Check all machine functions for correct operation.
