Question about Cars & Trucks
I set the timing marks on the gears were I thought they belonged but not sure if right, went to start tractor and would not start, gave it a small amount of starting fluid and it starts on this but stalls, checked to see if getting fuel at injectors and it is, the exhaust looks like it is getting fuel please help
If you know where the timing marks are supposed to be the use the old method of cam/crank timing to check and adjust to where the marks will be. Remove no 1 injector and turn the engine over until no 1 piston is coming up on injection stop when you reach TDC. mark on flywheel of harmonic balancer. If there is valve clearance ot both rockers turn the engine another 180 degrees and bring the piston to TDC again. watch the rockers and if you turn back a few degrees or turn forward a few degrees you will see ( in the forward direction) the exhaust valve closing and at the same time the inlet valve will be opening. This is known as valve rock. As you move the piston bacvk and forward over TDC you will see the valve movement. set on TDC and check the timing marks with the positions indicated. Remove and reposition the cam shaft gear to achieve the correct mark alignment or pull the cam shaft out just enough to realign the teeth to the mark. At the most you will be about 1 tooth out. The pump timing will be out 180 degrees as you are setting the valve timing on the induction stroke and you will need to turn the engine 180 degrees to compression stroke for the pump timing marks to line up. the injection mark on the flywheel is what you are looking for and when it is at the correct number of degrees as indicated by injection / lightning flash sign then the marks for the pump should be just about lined up
