6. Full-load Quantity for Starting a warmed-up Engine
When the engine is warmed-up, it is not necessary to operate the lever (9) for additional fuel.7. Stopping the Engine
For stopping the engine, the starting and stopping lever (9) must be pulled beyond the starting position until it rests firmly against the stop. When pulling the lever slowly, the engine will speed up again before stopping.8. Operating the Tractor
The hydraulic governor of the distributor-type pump functions in the same manner as a mechanical governor (RSV governor) of an in-line pump. It is, however, more sensitive to response than the mechanical governor.Pump Illustrations
Fuel Circuit Of Distributor - Type Pump
Checking The Fuel-Injection Pump Drive And Replacing Components (as from 3 cylinder engine)
1. Check the gearwheel and hub or injection timer. If necessary, dismantle the gearwheel from the hub or from the injection timer.2. Renew the defective component.
7-492.1 Assemble the gearwheel and hub so that the punch mark registers with the groove in the hub.Fig. 7-49, right2.2 Assemble the gearwhell to the injection timer so that the recess in the former registers with the groove in the hub.Fig. 7-49, left Important:As from 1975, the hub was modified in the case of rigid drive.
7-502.3 In the case of in-line injection pump, mount gearwheel onto steel hub.Fig. 7-50, right2.4 In the case of distributor injection pump, mount gearwheel reversed onto the hub.Fig. 7-50 left Observe markings and angular degrees.Dismantling And Installing Injectors
Dismantling:
1. Dismantle leak-off line to injector. Disconnect injection delivery line on injection.2. Dismantle stirrup and remove thrust piece.
7-513. Remove injector using extracting device No. 150800.Fig. 7-51, Attention:In addition, use threaded piece No. 110050 in case of lateral connection of injection delivery line.Fig. 7-51, leftUse extractor No. 110030 in case of top connection of injection delivery line.Fig. 7-51, right
7-52On FL 912 W remove injector by special wrench No. 110010 plus insert No. 110020.Fig. 7-52
7-534. Remove joint washer from injector or from cylinder head, as the case may be. (Extractor No. 120630)Fig. 7-53, leftIn case of FL 912 W, remove heat insulating plate (using, for example, bent wire).Fig. 7-53, rightInstalling:
7-541. Stick new joint washer with grease (graphited side facing towards injector).Fig. 7-54 On FL 912 install heat guard as shown.Fig. 7-53, right2. Install injector.
7-553. Install thrust piece and place stirrup in position.Fig. 7-55, left4. Place washer with convex side facing stirrup and screw on nut.(See Specification Data)5. On FL 912 W align injector to injection pipe.Fig. 7-55, right
7-566. Tighten injector by special wrench No. 110010 plus insert No. 110020.Fig. 7-567. Tighten injector and fit leak-oil line with new sealing rings.Removing And Refitting Injector On Engine Provided With Exhaust Air Heating
Preliminary work:
Injector is removed.1. Stick by means of grease sealing ring to injector and insert the latter in the cylinder head.
7-572. Slip rubber seal on injector and the vertical pin (see arrow) for fixture.Fig. 7-57
7-583. Apply leak oil pan (arrow). Slip spring and spacer sleeve on pin for fixture.Fig. 7-584. Apply clamping piece and fixture.5. Apply washer the curved side of which must show towards fixture; screw on
