Gear Timing
The camshaft and high pressure fuel pump are driven off the crankshaft. The timing gears are accessible by removing the front cover. The camshaft, crankshaft and high pressure fuel pump all need to be timed together.
Note: The fuel pump is timed so that the fuel pump stroke happens at the same time as the injection stroke.
This provides a more consistent fuel delivery. See the Workshop Manual for the specific procedure for timing the crankshaft, camshaft and fuel pump.
