My latest weekend project!!!!

Thats pretty! I need to get mine rebuilt for my spare engine (need to get started on rebuilding that too!) Good luck!

I got my rebuild kit from classicpreservation.com , very nice kit,and only $73 plus shipping. Very good instructions for disassembly / assembly. I'll let you know how everything goes after this weekend. Far cry from the price they want for a new rebuilt one. Bruce

Yeah, post up after you're done with it and tested it out on the Jeep - I'm sure I'm not the only one interested in the outcome. You can even write a review on the kit in the product review section if you want.

A two page instructions sheet will help but won't even come near the wealth of information we have here for free:

SUCCESS!!!!! Pump went back together pretty easy,just have to watch you keep shafts lined up with holes in gaskets when you stake shafts to diaphams. Put it back on jeep, fired it up, it now idles better and at a slower rpm. I'm very happy with it. Anyone need one rebuilt? LOL,I would do it again,not a bad job at all.Now if this snow would go away, I could get out on the roads for some fun!!!! Bruce

Nice - good job!

Good job. I was going to rebuild mine when it was giving me problems this past summer, but ended up just getting one from John at Midwest Mil. because I was short on spare time and didn't want to fiddle with it. But it looks like it went easy for you.

Great job! I'm in the middle of rebuilding mine right now with a parts kit purchased from Then And Now. I have everything disassembled, bead-blasted, and painted. Now it's time for reassembly.

Everything looks good with my kit, the only part that I am unsure where it should go is a piece of mesh that came in the kit.... did yours come with this mesh as well?

Hawkshadow, Mine didn't have the mesh but reading the manual wes posted, it was a filter on the vaccum side but is not needed,I'll see if I can find where it states that and post it in a bit. I never saw one painted, when you get it done how about a pic. Bruce
Here it is from manual,e. Disassemble Vacuum Cover. (Superseded) Remove valve and
cage retainer screw. Lift out retainer, two valve and cage assemblies,
and two gaskets. Remove cover screw and its gasket. Lift off
cover, cover gasket, screen retainer, and screen. Discard screen and
screen retainer. The vacuum section screen serves no useful purpose
and has been eliminated from later production pumps

Ahh that makes perfect sense. So I don't have to worry about it. I am hoping to do my re-assembly within the next couple of days and will upload the pictures as soon as possible.
While I haven't seen one painted before, I ended up doing mine the same colour as the engine. I started just doing the topper on the vacuum which had rust spots, but then that would've looked strange, so I ended up blasting and doing the whole thing.

Any pointers to pass along before I start the reassembly?

Actually they were not painted. They were anodized and you can still replicate that coating with the use of Alodine today.

Only pointer I have is "CLEAN" , just make sure everything is clean and everthing moves as it should,and don't rush,take you time and make sure everything is lined up right the first time. Bruce

I am working through the re-assembly and have hit a couple of bumps along the way. I am taking detailed pictures and hope to post a step-by-step for members here.

Bruce, Do you recall which way the linkages for the diaphragms were positioned? I had it pictured at dis-assembly, but the picture didn't turn out well enough to be as helpful as I expected and they were mixed around when the bushing fell out in the bag

Picture from dis-assembly:


Which way should these sit and point?


Re the requirement for paint, here is what I had to start with. It appeared to have been painted the same colour as the engine at some point.


Thanks in advance!

Looks ok the shaft that rides on cam in engine points down towards bottom of pump, vaccum hooks to long arm, gas to short. that answer your question?
