I've read 2 write ups that contradict each other.

When marking your new (desired) timing mark, do you mark it to the right of TDC mark, and then rotate the motor counter-clockwise so the desired mark is now at the TDC?
 
If you retard your engine you advance your injection pump if you advance your engine you retard your pump. Counter clock wise will increase your timing ( pump gear off of course)
 
Yeah, I just wanted to make sure. They way one write up described it made sense, the other didn't.

To clarify in my tired overworked head: Retard the engine so the injection is earlier.

And to advance 8* would be about 1/2in turn (marked on the outside of the damper) roughly? I'll actually measure and do the calculation of course, just want to make sure I got it right.

Yep 1/4 in is roughly 4* and you are correct on the retard the engine advance the injection event. And if you can check it when your done it's best cuz you never know what timing you started out with unless your truck is 100% virgin

It's not, but the timing was set to 15* about a year ago, I've put 30k on since then.

I think me and walmart are the only people awake right now.
 
Lol I'm "working" aka baby sitting reliable equipment so I'm in a helpful mood. But I always double check and if your going to 23* at least re torque the stock bolts ;-)

I have new bolts for it lol

I'm working too. Just sitting watching an alarm panel and a bunch of planes on a quiet base.
 
You didnt happen to be reading my writeup?? lol cause i may have wrote it wrong and got my clock wise and counter clock wise's mixed up!!
 
I think your's was one of them lol I've read so many now that I don't know why anyone pays to have their timing set. It really is a simple process.

Here is the math: Balancer diameter X (Pie) 3.1416 divided by 360 X degrees desired.

Yeah, I knew the math, but didn't want to figure out the exact answers in my head. I just remembered someone saying that 3* is almost a quarter inch.

Thats exactly my thought. Anyone who passed the 7th grade can figure it out!!
