I'd mike the paper, and then (for example) Google .010 gasket paper, get a roll and cut it out myself.  They are easy enough, tape a slightly bigger piece of paper than you need to the pump, take a ball peen hammer and tap lightly around the edges, and at the bolt holes, and the paper is marked for cutting...Wink

the gasket should be as thin as possible without having the rotor drag the cover.. It might be 3-4 thousands.. You can put a straight edge across the case and measure the rotor depth with a feeler gauge.. .... if you use permatex you want a VERY THIN see thru layer on the gasket... normally you can soak the gasket in oil and Squeeze it  with the cover..

a piece of construction paper or note book paper might the the right thickness.
Like them all, but love the "B"s.

Dave,
 Yes, I have done that with several gaskets in the past. Getting lazy. 
But now would be the time to do it over. Story of my life.
Thanks for the input.
 Regards,

I smeared a very, very thin coating (like Steve said) on the pumps for my WD. Yes, plural... I rebuilt the original pump and then lucked into a much nicer shape AGCO retrofitted version so I went through it too before putting it back together. I used an old school shellac after flattening the bottom plate as much as I could with glass and a sheet of sandpaper.

Disclaimer... it's not running yet, ha. You're still way farther ahead of me on this CA than I am on my WD that keeps falling to the backburner. And I have a CA project that needs to go into the shop sooner rather than later. I can't wait to see your tractor back in tip top shape!

Guys,
 Thanks for the ideas and support on the CA oil pump. I mean it is the heart of the system. I am great for doing things twice, or maybe even three times! So I may pull it off and clean it up again and start over I also got some good advice from a CA expert. That's what I like about this forum. Great suggestions, and recommendations! I should ask before I act. But that's not like me. More like the bull in the China shop!
Regards,

Allis folks,
 So I took the CA oil pump back off. Several things to improve/ redo. First I forgot to put the gasket from block to the pump. Found the gasket in with the others in the gasket kit. Oops!

Second I took the pump back apart and cleaned the mating surfaces. I reversed the vanes in the pump. I was told this may improve the oil pressure a little. All for that, and the vanes seem very happy reversed.

Cleaned the outside cover plate. Very little wear on the plate. I suppose I could try to get those shallow grooves out of it?

Was warned that Allis may have made a small and large oil pump. Well the gasket I have does not fit well, so maybe the pump I have is a big pump? Have to measure the gasket thickness and maybe carve one out of a sheet. Unless there is a large pump gasket out there?

I did get the dial indicator to play with at some point too. Maybe use it to reset the valve clearance more accurately?

Merry Christmas to all forum members and their families!
 Regards,
 Chris and Cheryl
