Default Timing the VE44 Pump

Ok guys, I thought I had everything figured out then I saw a thread on another forum where the guy was doing WAY more than I thought so here I am to pick your brains.

I want to time the VE pump by jumping 2 teeth and then retarding the pump 1/8" to get around 16* of timing advance.

I pulled the timing cover and the pump gear, turned the pump to where the keyway lines up best with the gear in the advanced position, and am going to loosen the pump so I can wiggle the keyway the rest of the way into the gear. Is this the right way to do it? I have the gears lined up right and everything, but the thread I was looking at was showing some guy with a dial indicator gauge doing way more than I thought he would need to...

Did I screw up or am I on the right path?

Second, how much pump adjustment can I get, I know people usually leave the timing gear stock and advance the pump 1/8" to the head. I was thinking with the 2 teeth skipped I could retard the pump away from the head so it would be easier to get to everything. In the winter I am thinking I may need to retard timing for cold starts.

So, my second question is how much room would I have to pull the pump away from the head? I figure a 1/4" of retard would be like running the gear one tooth advanced, which should be fine in the winter most of the time. Am I right?

Thanks in advance for the help!

Stock timing is in the neighborhood of 12 degrees. Each tooth is 10 degrees. If you want 16 degrees, try rotating the pump about 1/8"-1/4" from stock. To the head is about 18 degrees.


If you feel you must skip a tooth, pull the pump gear and not the pump. Advance it a tooth and let the nut on the pump shaft pull it back into place. It may take a time or two to get the process down pat, but it's not that hard.


And its just a VE. Not a VE44. 2nd gen 24 valves have a vp44.


Here is a pic of one tooth advanced:

On edit:I can see the pic when I preview the post but not on my actual post. May just be my computer, but if you open the link you should be able to see it.

Thank you for the reply! I actually figured it out. What the guy in the thread was doing was measuring the timing, it really confused the hell out of me. I thought if I rotated the pump that I could fit the key in the keyway, but all I had to do was turn the crank! Stupid brain farts. And I was looking for 16* MORE advance, for a total of 28* or so.

I appreciate the reply. I think typing all of this out helped me pass the brain fart. It was quite hilarious when I figured out what I was not thinking through correctly
