I have two mechanics working on two Isuzu E120 engine (one spare) to be fitted onto Hitachi EX400 excavator. Here's the problem, both of them gave me two different firing order.Mechanic A: 1-5-6-3-2-4Mechanic B: 1-4-2-6-3-5I think i just realized something ... instead of clockwise, can it turn anti clockwise? because the engine is designed to go anticlockwise the numbers would make sense now.
If it's a 3.1 or 3.2 V6, order should be 123456, where #1 is 1st cylinder on the left when standing in front of engine.
