Static timing:
The engine check angle must be used with special tool MS.67B and with the engine set with number 1
piston at top dead centre (TDC) on the compression stroke. The pump is checked with the pump set at
the start of injection for number 1 cylinder.
The code letters are included in the setting code stamped on the data plate of the fuel injection pump.
Some fuel pumps may have the setting code stamped on a modification plate which is fastened to the
flange of the pump. If a modification plate is fitted, use the code letters stamped on this plate. A typical
setting code is 2643C601BM/4/2860; in this example the code letters are "BM".
