           The Controller washer with negative adjustment increases the feed for increase engine speed.
           Mount distributor piston housing in such a way that the milling at the piston foot lock at the driving pin of the cam
           disk.
           Mount controller disc place operating pin into the fit in the slider.
           After mounting of springs in the spring plate and the pressure spring In their seats, fit the hydraulic head in the
           pump element and insert into the pump housing fix the hydraulic head by means of our fastening screws which
           have to the tightened by mm of tightening torque of 11/13 Nm
           ADJUSTMENT OF DISTRIBUTOR PISTON POSITION (DIMENSION ‘K’) Mount the indicating calliper in special
           tool and adjust it to zero on the surface plate with a pretension of mm.
           Place the tool with indicating caliper at the hydraulic head
           Check dimension “K” which must be mm

           The dimension K is the distance between the sealing surface of the head and the surface of the distributer piston
           If dimension “K” deviates from the specification the adjustment washer below the foot of the distributor piston must
           be replaced.

           Mount plug with vent screw and tighten up to  a torque of  60/80 Nm.  Mount feet  valves and pressure pipe
           connections and tighten torque of 35/45 Nm. Mount solenoid valve.
           Mount locking clamp at plug and insert it into the adjusting bushing
           Parts of the controller group

           1    Fastening hub nut of the governor shaft                         2     Plain washer
           3    Governor shaft                                                                4      Adjusting plate
           5    Compensation washer                             6     Housing governor group
           7    Weights                                                                           8      Distance washer
           9    Adjusting bushing

           Place in housing of the controller group the weights the plain washers (5 and 8) and the adjusting bushing
           Mount the shim and the controller group in the pump housing. Screw in the shaft .
           The adequate adjustment is carried out subsequently on the test bench.
           Adjustment of the Governor shaft

           Control with feeler gauge that the shaft end piece of the controller is placed at a distance of 3 mm from the pump
           housing flange.
           Adjustment Governor shaft
           A_3 the exact adjustment is carried out subsequently at the test bench.

           Adjustment of the Starting Dimension “MS”
           Place tool between housing and governor lever place the feeler gauge between the control lever and pin. This
           distance is Ms Dimension. If not is range adjust the controller group.

           For different valve dismount controller group once again out of the pump housing remove plug from the adjustment
           bushing and replace by a different one with an adequate size. Remount the controller group into the pump housing
           Check pressure increasing control value
           Pull out the locking clamp by means of tool pull out piston and spring out of valve housing.

           Pressure control value
           1  Elastic locking ring             2     Piston 0
           3  Spring                                                 4     Sealing ring
           5  Valve housing                                     6     Sealing ring
