Read the injection angle recorded on a reassembled fuel injection pump and calculate the difference from the injection angle of the disassembled fuel injection pump. (When re-installation does the same fuel injection pump, the angular difference is zero.)
Fuel injection angle difference (cam angle) = (the fuel injection angle of a reassembled fuel injection pump) (the fuel injection angle of a disassembled previous fuel injection pump)
