These lines can get eaten by the newer blends of biodiesel which will disintegrate them and fail. Fit the timing belt cover 19. I have no idea if this actually works. As for replacement - I'd consider having a Stanadyne shop do the work. It was demonstrated to me by taking your fingers and folding the short drain-back hose coming off the injection pump in half to pinch it shut; the engine very abruptly shut down, just like turning off the key would. I have a knock in Cylinder 1 In my 99 H1. Local shops here in Phoenix charge about 1100-1200 dollars: pump removal, refurbish, and reinstall.
Use another screwdriver to hold the lock plate in place. 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. This injection pump can be used in naturally aspirated and turbo charged applications. Low residual fuel pressure can cause hard starting and vapor lock during hot weather. May 16, 2011 I repaired a 3.
This reduces housing pressure to near zero, so that the transfer pump pressure behind the power advance piston can easily advance the cam ring. A timing test performed with an electronic timing set would help discover this problem. Be careful when you remove it so you don't loose the coil spring that sits in the hole. When there is too much fuel pressure, the engine runs rich. If your engine develops a bad knock it is probably due to a bad injector. If you do get a pressure reading but the reading is lower than normal, the cause may be a weak pump, a blockage in the fuel line, filter or tank inlet sock, or a faulty pressure regulator. A higher reading would indicate a restricted fuel return line.
My truck still blows a ton of white smoke and still idles very rough, to the point it's now nearly stalling until the engine warms up. To prove whether it is the injector swap it with the next one and see if the problem follows the injector. If the pressure rating does not go up with the return line blocked, the pump may not be able to deliver enough fuel at higher engine speeds. Connect the negative battery cable. Rotate the crankshaft 2 full turns clockwise to bring the No.
Loosen the tension pulley nut to take up the timing belt slack. John Klatte told me that in 'time set' mode i should get a reading of 3. It is an electrically controlled valve that shuts off the flow of fuel to the injection pump. Don't forget that low voltage at the pump can also prevent it from running fast enough to generate adequate fuel flow. Remember, we said this is a possible cause to the problem, not a definite fix. Remove the valve cover 3. If everything is working properly, the actual injector timing should closely resemble the desired injection timing.
Remove the injection pump sprocket flange. Any ideas Could be a partially blocked injector, when they are blocked it sounds like the big end is gone. This most certainly could be a multiple failure situation. Turn the tensioner clockwise to align both marks 10. Keep it clean and don't let dirt get into the pump. Repeat the procedure if required 16.
Turn the engine by hand 'till the piston contacts the bolt. Your timing mark on the pulley should be exactly between the two marks you made. Not starting, stalling, hard starting, and hesitation are injection pump symptoms. If you are working on a vehicle that does not have a pressure test fitting, you will have to tee a pressure gauge into the fuel line just ahead of the injector fuel rail. The valve can leak, the coil in the valve can go bad or you can have have failing electrical connections which will make it at best intermittent.
If it is radically off, replace the pulley. If pressure drops quickly, the vehicle may have a leaky fuel line, a leaky fuel pump check valve, a leaky fuel pressure regulator or one or more leaky fuel injectors. Fuel Pressure Regulator Tests This test checks the operation of the fuel pressure regulator to make sure it changes line pressure in response to changes in engine vacuum. First, check that the engine is getting uncontaminated fuel and there is no water in the system. Measuring Fuel Pump Pressure Depending on the application, the fuel system may require anywhere from 30 to 80 psi of fuel pressure to start and run. Diesel Fuel Return line Kinked This will kill your engine. If pressure at the engine fuel rail is even a couple pounds less than specifications, the engine may not start or run well, or experience hesitation or stalling problems.
Tighten torque: 20 Nm + 20 degrees 18. Replace the connecting rod and bearing and the knocking noise will go away. The lower half is held in with a T-40 screw and a plate. Make sure the 1 injector did not over-pressure the cylinder causing a hydrolock condition which would bend the connecting rod. Install the injection pump sprocket flange; the hole in the outer circumference of the flange should be aligned with the triangular timing mark on the injection pump sprocket.
When the desired timing goes to zero, watch the actual timing. You can also disconnect the battery which will supposedly clear the codes. The compression will be around 80-100 psi lower than cylinder 3 if this is the case. With the engine off, energize the pump and measure the volume of fuel delivered during the specified interval of time. Or if it does, it may idle roughly and run poorly. Hope this helps Posted on May 22, 2009 Hi there the crank,cam and diesel pump gears normally aligned in a clockwise numerical order with centre idler gear between all gears.
