I had originally set my timing to 16.5* with my homemade timing kit (I know BIG mistake).
Since then I have ordered the Snap-On SP500 kit, it should arrive in a few days.

But anyways, I just redid my cylinder head with o-rings, studs and a .020 marine gasket.
Now, I want to reset my timing to around 18*.

What is the best way to do this?
Do I need to compensate for the advance in timing already?
In other words I originally set the pump to 5.7mm of lift. I now want to go to 6.0mm of lift.
Do I just advance the pump .3mm of lift?

Also, It might just be easier to go back to stock and start over. But how do I go about doing that? I have read about pulling the pump timing pin cover and pinning the pump and then popping off the timing gear and setting the engine to TDC, and that should be stock specs.

I dont know.
My head is all plugged up because of this nasty cold I have and I just cant make sense of it know.
Thanks in advance.

hi
make sure you use the correct cpl setting for your pump !!

if 6 is correct number by col list , that is what you want when finished , so after you reset it ,
just recheck your setting agin to see if it is what you have !

When you time your truck, with the dial in, bar the engine in until the dial stops moving at its lowest point. Zero it, then bring it up to the desired lift. Pop the gear, roll the engine back past TDC, then forward to TDC. Reset the gear. Easier said than done. It helps to pop the gear off before you get the pump to where you want it, reset the gear lightly and bring it up to the desired lift. Pump will jump if you pop the gear off after it was at full torque.

Any pics of your timing kit? Mine is a home made jobbie, and its worked fine for me.

Just got my new snap-on kit today.
Problem I was having is the dial indicators I have arent long enough for a 215hp pump. I would run out of down stoke on it.
I just gave in and bought the snap-on kit.

My homemade one consisted of a drain plug for our cummins drilled to fit the indicator. I had 2 indicators 1 in metric and 1 in inches. I also bought a point kit for them also.

Thats the way my kit is. I have a cheapo $20 1" dial that reads off the plunger, then I mount the metric dial on top. My metric is only 10mm, so I can't read the total lift of thepump with it even.

dieselman2300

What size pump do you have?
I have heard the 215s are alittle more testy to set.

Tate

Mine is a 215. I've only set it the once, took about a half hour (super easy when there is not front cover, or rad, or bumper, to be in the way). Timed it to 5.35mm (slipped back .05mm of what I wanted), has run fine for the most part. My pump has some issues, but I don't think it is timing related. I torqued the nut to 180 ft-lbs, and I rechecked the timing two months after I set it, and it was still bang on.

My snap-on kit came in yesterday. It sure will make setting the timing alot easier. The dial indicator has 30mm of lift.

I'm curious about your project. One of my rigs needs timing (smoking a bunch) and I'm looking at the same sp-500 kit. My dodge manual claims there is a thrust washer/bearing in the Miller kit they use and the snap-on kit does not. Just wondering if they are needed to get the pump gear loose. Also, where did you get it and how much is it? I found one for $236. Thanks, Shawn

Tate

The thrust bearing would be when setting the gear back on the shaft. The nut/washer without the bearing can turn the gear on the shaft as you tightening it, so it would advance the timing a bit. When I've set the timing on my truck as well as ccmckee's, I'd take larger socket (32mm I think), set it on the gear and give it a smack with a deadblow hammer. Helps set it in place.

I ordered the snap=on kit from snap-ons online site. It ended up being $250 shipped and I got it in 2 days.

Thanks guys for the info, my kit will be arriving shortly. One last thing, when I do finish timing; do I need any parts (gaskets, o-rings, etc) for putting it all back together. Thanks again.

dieselman2300

nope.
Only thing you should get is a new pump shaft
lock washer.
bosch#-2 916 699 091
cummins#-3920922
or you can use an M20 lockwasher.

Oh, you will need some good qualitybrake clean.
do you have the info. on how to set the timing?
