I'm having trouble installing points

I am (trying) to install a new set of points in a Delco Remy 622-R positive ground distributor.

It does not have what looks like an insulator in this picture of a Delco Remy 622-L.

Since this part seems to be misssing, what can I use?

Thanks,

Dwight

If you're speaking of the non-conductive piece that insulates the threaded post as it passes thru the distributor body shell, simply make something suitable from a piece of nylon or other plastic.

You need an insulator where the wire comes in, and an insulated bushing for the points to move on and an insulated rubbing block at the cam. Something heat proof and hard wearing. The originals were probably Bakelite or Micarta, today there must be improved plastics but I don't know exactly what.

They used the same setup on points ignitions up to the seventies, it is possible you can cabbage suitable replacements from a newer Delco distributor or points set if they kept to the same dimensions.

Or you might be lucky and find an NOS set to fit your distributor. I assume they are no longer made or no longer available thru normal channels or you would have just bought some.

I cut a piece of plastic soda bottle to wrap around the back of the points.

With the points "open" there is voltage on the side of the contacts wired to the ignition coil and condensor, and no voltage anywhere else.

Using an ohm meter there is continuity between everything I touch in the dist. Am I missing something here or just going insane?

It's running now!

I don't know what the continuity thing is, but it must be OK.

Thanks Rusty and Owen.

I will find something more heat resistent than the soda botlle.

The movable points must be insulated from the distributor. They ground thru the fixed point when they close.

I suspect you originally had a bushing in the hole with flat washers on both sides, made of bakelite or mikarta, all held together with a little bolt. The head of the bolt held the spring. On the outside, went the wire from the coil.

Iam guessing the continuity might be do to a cooked condensor. I will check that.

Dwight, sounds like you have it figured out. Here are the components to hold the movable points on my Plymouth, just as Rusty_O explained. The rectangular paper is between the distributor body and movable points.

Had that type of problem on a 1970 VW transporter had bought a new set of points from K Mart had a missing problem would run ok at speed of 45 and above but at slower speed would cut out an quit . It had a bad fiber board on the points. Cut a plastic lid of a coffee can to insulate to prove the point and it work ok so I could get to the next town with a auto parts store to buy a new set of points the best for sale .
