Replace the delivery valve and spring and remember to remove the timing pin, (if used), before cranking the engine. If I remember rightly it was considdered OK when you acheived one drip in 15 secconds or more. Fit the pump in this position.Ī spill pipe should realy be used but I never bothered, this was an open ended swan neck of injector pipe from which the fuel would drip till the spill cut off point was reached. If you keep blowing away the fuel from the fitting as you turn you will be able to find this point quite accurately. Turn the pump slowly in the direction of normal rotation till the fuel just stops flowing, this is the spill cut off point. 1 connection when the lift pump is opperated. To do this you need to remove the delivery valve and spring from under the No.1 injector pipe fitting.įully open the throttle and set the stop in the run position, fuel will then well out of the No. If you have no timing tool you can allways go back to the old method and spill time the pump. Either way set the pump on its mark, (No 1), put it on and that should be all thats to it. Other pumps have a mark on the pump boddy and require a timing tool, (pointer), attatched to the shaft which is then turned to allign with the mark.
Some have a plug, (window), in the flange with a pointer to line up with a mark on the back of the gear. I immagine this is a gear deiven pump so there will be a mark somewhere on the pump mounting flange to line up with a mark on the pump gear. Set the engine up to this mark or pin then all you have to worry about is the pump. Some engines have provision for a pin in the flywheel housing which will locate in the flywheel, but all the IH engines I worked on have a sight window in the housing with a pointer to line up with a mark on the flywheel, which will probably be marked INJ 1&4. There will be a means of locating this point accurately. Turn the engine back a little over a quarter of a turn, that will be near the point of injection,( 15 to 28 degrees before TDC?). 1 piston will then be at the top of its firing stroke. 4.īest way to do this is to remove the rocker cover and turn the engine till the exhaust and inlet valves for No. The engine will make two revolutions to every one made by the pump so first check that it is on the fireing stroke on No.
