Fitting a diesel pump and adjusting the timing, also known as "timing setting" or "tab timing," is a precise task that requires mechanical expertise and specialized tools. This process is typically performed by experienced mechanics at a professional automotive workshop. If you're not experienced with diesel engines and their components, it's strongly recommended that you seek the help of a qualified mechanic to perform these tasks. Incorrectly adjusting the diesel pump can lead to engine damage or poor performance.
Here's a general outline of the steps involved in fitting a diesel pump and setting the timing, but remember that this is a simplified overview and should not be attempted without proper training and experience:
Prepare the Vehicle:
Ensure the vehicle is parked on a level surface and in a well-ventilated area.
Disconnect the battery to prevent accidental starting while working on the fuel system.
Locate the Diesel Pump:
Locate the diesel injection pump on the engine. The exact location and type of pump can vary depending on the make and model of the vehicle.
Prepare for Timing Setting:
Remove the timing cover if necessary to access the timing marks on the engine.
Locate the timing marks on the engine's crankshaft pulley and the camshaft.
Timing Locking Tools:
Many diesel engines require specialized timing locking tools to hold the crankshaft and camshaft in the correct position during the timing adjustment. Consult the engine's service manual to determine if these tools are needed and how to use them.
Mark the Old Pump Position:
Before removing the old diesel pump, mark its position to ensure you can return the new pump to the same position initially.

Disconnect the fuel lines, electrical connections, and any other components attached to the old pump.
Carefully remove the old diesel pump.
Install the New Pump:
Install the new diesel pump in the same position as the old one. Ensure all connections are tight and secure.
Setting the Timing:
Use the timing locking tools to hold the crankshaft and camshaft in the correct position.
Follow the manufacturer's specifications for timing settings, which may involve aligning specific marks on the pump and engine.
Adjust the pump's position until the correct timing is achieved.
Tighten the Pump:
Once the timing is correctly set, tighten the pump mounting bolts to secure it in place.
Reconnect Components:
Reconnect all the fuel lines, electrical connections, and any other components that were disconnected.
Double-Check Timing:
After installation, double-check the timing to ensure it remains correctly set.
Reconnect the Battery:
Reconnect the vehicle's battery.
Test Run:
Start the engine and monitor its performance. Listen for unusual sounds or signs of poor performance.
Final Checks:
Check for any fuel leaks.
Recheck the timing if necessary.
Dispose of Old Parts:
Dispose of the old pump and any other components properly.
Please note that this is a high-level overview, and the specific procedures can vary depending on the engine and diesel pump type. It's crucial to consult the vehicle's service manual or a qualified mechanic for detailed instructions and guidance tailored to your specific vehicle and engine. Attempting this task without proper knowledge and tools can lead to serious engine damage and safety hazards.
