Distributor revision, 2 questions

[Werner]

I am currently overtaking the original distributor.

Mr. Les Andrews recommends drilling the distributor shaft vertically and horizontally a hole in order to lubricate the two bronze bearings through the distributor cam screw.

He writes a vertical diameter 3/16 and horizontally 3/32 ", which seems me too big. I drilled therefore only 1/12 resp. 1/6 ".
I think, the thin side drilling is sufficient for thick 600 oil, because of the centrifugal force.

Does anyone have a comment on this?


Second question: Under the "collar" of the shaft above must be a thin washer. It was missing from my. What is the thickness/clearance? (Picture sample copper ring.) The shaft has a vertical clearance play of 1/10 "!


Thanks in advance for the always good replies!

I wouldn't use 600 wt lube to oil the distributor. Use motor oil. I would use a 1/16th washer, which is .0625

If you read the instruction book it says to "fill" the oil cup---most dist call for a few drops----once I realized this and filled the oil cup with a good squirt and went for a drive I saw that the upper bushing got lubed---the top thrust washer was wet with fresh oil ----no need for the additional hole--
I also saw that original shafts the cam boss was on the same centerline as the shaft,(less than .0001 runout) and both surfaces were ground to size, the repros that I had were off by .003-.006, and the shaft was not ground to size

Good evening.


Thank you, Brian!

Kurt, I am not sure, if I understand you right. Do you mean with "Oil Cup" the attached pictured oiler?

Oil your distributor regularly, using motor oil. Have never had a problem. Never drilled any additional holes.

The holes had already been made yesterday. That is done ...


Today, I have made a step ahead, thought of me. I also drilled the cam screw. And cut a small screw thread in it.

For oiling, I now no longer need to release the central cam scew. Otherwise, because the ignition cam can be adjusted accidentally.

that doesn't look correct

Werner has a small regular sized head screw covering his oil lube hole in the cam retaining screw. A nice touch.

Werner COULD buy the shaft and cam retaining screw already drilled, no cover screw.

Not necessary but does prevent a sudden "squeal" should the upper bearing not get lubed by the side lube port.

The same excellent quality as our A-12178-S except we have drilled the top of the shaft so you can oil the bushings by simply lifting the rotor and dropping oil through the center of the cam screw. Comes with cam screw and washer. U.S.A

In hindsight, you could have drill a hole thru the center of the cam screw.

That's it, it has a spring in it, you pull it out to reveal the hole for the oil.

That I had done, see picture.

Katy: That is it, thanks!
