* A timing light
* A wrench
* A screwdriver
* A feeler gauge
* A rag
* Diesel engine specifications (This information can usually be found in the vehicle's owner's manual.)
Step 2: Prepare the engine.
* Ensure the engine is stopped and cool.
* Disconnect the battery.
* Remove the valve cover.
* Locate the timing marks. These are usually two marks, one on the camshaft gear and one on the crankshaft gear.
* Rotate the crankshaft until the timing marks align.
Step 3: Set the fuel injection pump timing.
* Loosen the fuel injection pump mounting bolts.
* Rotate the fuel injection pump until the specified injection timing is achieved.
* This is usually done by aligning the injection pump timing mark with the mark on the engine block.
* Tighten the fuel injection pump mounting bolts.
Step 4: Reinstall the valve cover and reconnect the battery.
* Start the engine and check for proper operation.
Here are some additional tips for setting diesel engine timing:
* Use the feeler gauge to check the valve lash. This is the clearance between the valve stem and the rocker arm. The correct valve lash should be specified in the vehicle's owner's manual.
* Rotate the crankshaft in the direction of engine rotation when adjusting the timing.
* If the timing is off by more than a few degrees, it may be necessary to remove and reinstall the timing belt or chain.
* If the timing is set incorrectly, it can damage the engine. If you are not confident in your ability to set the timing correctly, it is best to have a qualified mechanic do it for you.
