Timing
So ive been searching all around this site looking for how to adjust my timing. Does anyone have any pictures or diagrams or is it pretty simple?:s:
|
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
|
umm you don't need a dial indicater for our trucks as far as i know
|
In the manual for the pump it shows you how to use the dial indicator to locate what would be TDC. So yes, if it is out AND out of time then you use a dial indicator.
|
i stand corrected
|
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.

I guess we both stand corrected in a way then seandonato73.
All I know is last night I was looking in the cummins injection pump manual and is was showing how to locate TDC.:moon: |
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.
|
I would just time the pump to what specs say and then after the pump is on, time it to ear
