Timing settings on john deere 2140 four cylinder tractor
Setting valve timing isn't rocket science. Step 1 is to turn the crank until the timing mark on the pulley is aligned with the mark on the block. If you can't find the timing marks remove the no 1 spark plug or injector. Place a straight piece of wire into the hole and slowly turn the crank until the wire is pushed right to the top. At this point there will be a slight movement of the crank either way where no movement is felt or seen on the wire. This is called top dead centre (tdc) on no. 1 cylinder. By the way, no 1 cylinder is always the cylinder nearest the radiator.
The next step is to turn the camshaft - assuming the tappet cover has already been removed - and to watch for the point at which the no 1 cylinder's valves "rock", that is, the exhaust valve closes just before the intake valve opens. Watch the tappets, they will alternate as you move the camshaft, which by the way is not easy to do since you have to overcome the compression of the valve springs.
Once you have no1 tdc set and no1 valve set rocking, attach the timing chain and replace the spark plug / injector.
If your tractor has a petrol (gasoline) engine, remove the distributor cap. See that the distributor rotor is pointing to the no 1 spark plug wire position on the cap. Turn the engine anticlockwise just a mite off tdc, and see if the point gap is just breaking.
If all these timing issues are sorted, the engine should kick over without any hassles.
Have fun, mechanics are a gas.
1999 Nissan Sentra 1.6L sets p0304 code
check that your spark plug wires are all secured tight. the far right cylinder is giving you the issue, cylinder #4. Is the engine light flashing while the car is running? if it isnt flashing, then its a past code and isnt misfiring anymore. if the engine light is flashing, you either have a bad plug wire, or a bad ignition coil/distributor.
Why can't I shift to reverse, third and fourth gears?
What does the gearshift lever feel like? sloppy? it could be a loose linkage between the lever and the box.
Other than that, it could be a blocked valve body. This entails lifting up the vehicle on an overhead lift, draining the automatic fluid, removing the oil pan from the box, removing the valve body and cleaning it out. Normally a professional's job, but you can do it in your home workshop if you have the courage.
How do i replace the plate that connects to the fuel pump wiring harness prongs
Most auto supply stores will want the part number off of the pump and they will get you the proper plate. If you are asking how do you remove it, you will need a copper punch and a small hammer and tap it out equally all around in increments. Gently or you may damage the seal. same procedure in reverse when you install it.
