Re: "Basics of Basics" Pump/motor disassembly and rebuild.

I rebuild one of these motors on my 68 Camaro years ago using the Body by Fisher manual.

Your photos should be a great help for people in the future.

I really, really wish I had known about the paperclip trick.

I remember that was the hardest thing, trying to get those bushings to stay back while putting the armature back into position. I think I remember trying to use some needle nose pliers, or tape, or something. It wasn’t easy.

Re: "Basics of Basics" Pump/motor disassembly and rebuild.

The bummer is in the manual there is nothing about the motor part. It shows how the pump works, it shows everything in the pump but nothing in the motor, it doesn't even show the armature seal.

You know what's funny is I personally came back to this thread to see how it goes together yesterday.

Re: "Basics of Basics" Pump/motor disassembly and rebuild.

Since this thread covers a leaking cylinder, I'll post up my finding.
My passenger side started leaking heavily in the 'down' position, so I took the top O ring out to replace.
The size is 3/8" ID and 1/2" OD nitrile.
I already had a large O ring kit with 200 sizes.
It stopped leaking immediately with this simple fix.

Re: "Basics of Basics" Pump/motor disassembly and rebuild.

Hmmm, what I am taking away from this thread is that it is very easy to rebuild the pump EXCEPT for the part where you have to destroy the little star gear which does not come in the rebuild kits...So..no solution to this problem? I'm very appreciative for this information but it looks like unless you have spare parts lying about, then this is not going to work..?

Sounds like it may be possible to remove the "gerotor" as John referred to it, without destroying it. If it gets some abrasions on it, they can be deburred, apparently, and it will still function. Just so I'm clear, is that outer ring supposed to move freely, or is it a press fit and the inner "gear" rotates inside of it? Does it have to be removed?

Brian, how is your top motor hanging in there? Any more leaks?

These things are indestructible, I find it hard to believe that getting it wet could "kill" it. Pull it apart and clean it up, I would bet it will work again.

Re: "Basics of Basics" Pump/motor disassembly and rebuild.

While working on my top cylinders, my pump/motor started dragging. Charged battery to make sure it was all the way up, but no help. Pulled my top motor and pump apart and it is surprisingly clean inside. No gunk, and gerator and ring came right out with no problem. Going to clean contact points as described by John, ordered o-ring kit from Camaro Central, and I'll put it back together this week to see what I have.

Thinking about installing a relay to help save the switch and hopefully make the motor work better. Also thinking about trying to replace seal/o-ring on leaking top cylinder, but afraid it won't last because I could see some pitting on the ram when it is extended. Doubtful that this could be sanded / polished out. Wouldn't have much to lose if it doesn't work.
