Thanks Doug & Rick!

Doug---you have a PM.

Hardened gears and rebuild kits with hardened gears swapped in were shipped out this morning. (to those who ordered and paid in advance)
It is great when a group effort like this one gets to the "finish line".

I know that Doc heat treated some extra gears so if you are building an engine you may want to contact him and get yourself one of these little "insurance policies".

Like James Brown used to say (and probably does still, now that he just got out of jail again) "I feel GOOD"!

I got my kits, today! Thanks, everybody. The shipping was $9.09, I think. Did I already pay for that? Or do I still owe for the shipping?
Doug, I am curious. What method did they use to case harden the gears? I expected to see some discoloration, or darkening of the metal.

Thanks guys. I got my pump kit today and everything looks good. I like the D.D. initials in the pump gear.

Nice to see that the case hardened gears and pump kits are getting to everyone.

Sharp eye NCDart, I do engrave "DD" and the date onto these gears for future tracking, that saves me "guesswork" if I have to debug a problem down the road.

As for the Heat Treatment, it is called carburizing and it did leave a black / gray "soot" on the parts, I just wire brush it off to get back that nice shinney look.

Mine got here today. Thanks Doug!!!!

If I remember my machinist's apprenticeship class correctly, I believe they pack the parts with carbon balls or beads in a sealed container and heat the container and the carbon penetrates the surface of the metal.

I realize this is an old thread, but I find myself needing to pull four oil pump gears. Two from Melling units and two from original Chryco pumps (64 and 68, I believe).

Neither my two jaw nor my three jaw pullers are getting the job done. Where might I find a puller like the one pictured above?

I searched a little more and found this:
So now I will be looking into finding an old tie rod end puller to modify. This site has all the slant six answers.

*EDIT*

Rather than rely on my admittedly poor fabrication skill, I bit the bullet and ordered one of THESE That should get me very close to, if not in, the ballpark for a useable oil pump gear puller. The price is right.

Reed, this type looks like it would focus more on the interior of the gear over the teeth, but if the opening is too wide, it also looks like you could put short hardened metal bars across the opening to get closer to center of gear.

Thanks, Brian! I think that is actually the one I bought. Great minds think alike!

to remove slant six oil pump gears I have a section of sturdy 2x4 with a through hole cut into it that will accept the internal pump rotor.

remove the oil pump cap and gasket and outer rotor, set the oil pump body on the 2x4 with the inner rotor positioned over the through hole,
and using a steel drift and a three pound hammer, drive the oil pump shaft through the gear, I do this job with the 2x4 on the garage floor to maximize
the hammer shocks. A couple of good hits and you are done. I have used this procedure on cast iron and aluminum oil pump bodies with no issues.
This process keeps the removal force centered on the gear and away from the gear teeth edges.

The same piece of 2x4 is also a fixture to rotationally position a replacement plastic distributor gear.

Very interesting tool. I will keep that in mind if the puller I got doesn't work out.

So rather than wacking with a hammer, just put your tool in a press..........

I was speaking to the unfortunate few like me that do not have a shop press.
For those that do,, press.
