I've got a KM385 (EPA) The engine has about 300hrs on it and the heads have never been torqued nor has the valve lash been checked. I took the valve cover off and measured the valve clearance and found 5 of measuring between 0.020" to 0.024" but one exhaust valve had 0.028". From what I read its supposed to be 0.011" for the intakes and 0.013" for the exhausts. Before I start setting the valves I need the cylinder bolt torque specs to re-torque the heads first.
I also want to check the fuel pump timing. I am referring to this post for the method but if someone has a better method I would be open to doing it another way.
I had a couple questions while inspection the pump.
Why are there slots on the high pressure injector lines? Mine are all installed differently and I wondering why?
Fuel Injectors Slots
I believe the timing is set by slacking the pump bolts and moving the whole pump within the slots right?
Pump Slots
I believe the first mark is TDC and the second mark is the pump timing mark right?
Flywheel Timing Marks
