Timing
theres a couple ways to go about this depending on where your at.If the pump is off the motor and out of time youll need a dial indicator and attachments to measure the plunger lift.If your pump is on your motor and you just want to advance the timing heres a video
You can totally disassemble the pump into the smallest pieces available, reassemble the pump, reinstall the pump on the engine, and time it without a dial indicator. The dial indicator is only if want it at exactly 17 degrees base timing for whatever reason.
Cummins was interested in making sure that the base timing was at exactly 17 degrees or whatever from the factory, for the sake of consistency from engine to engine, emissions, fuel economy, rated power, et cetera.
In reality, you're going to want to time the engine according to ear and performance. I imagine that Cummins put all of 0 seconds into tuning their engines before they shipped them to Dodge; we can afford to dial it in to right where we want it. Unless you're trying to meet OEM NOx specifications there's no reason to not time it several degrees advanced from stock.

I have a 4bt in my 85 and the 4bt come with many cpls.most with different pump and different timing specs.I would want to time a precise injection "by ear".Again im not sure about different cpls on the 6bt.
