Question More Distributor questions!

Guys.. I have my dist. out of the car and totally dis-assembled for cleaning and rebuilding. There is a little felt washer (which no local autoparts store carries) below the points mounting plate. What should the little felt washer be lubed with? Just regular motor oil?

Regular oil will be fine, degreasing first them will bring them back quite a bit. I have seen the felt washer in the NAPA catalog.

Re: More Distributor questions!

Thanks Mat... Since no local Autoparts store seems to carry the felt washers, I pressed as much old gunk out of it as I could. Then I washed it in hot water and dishwashing soap.
I re-oiled it with motor oil. Should be OK.

That felt washer (saturated with motor oil) provides the lubrication where the breaker plate rotates on the housing when moved by the vacuum advance.

Re: More Distributor questions!

In David Vizard's book, in the distributor overhaul section, he shows a plastic sealing washer that goes under the felt washer to seal the "grease well" What does the grease well do?

I assume that the plastic piece needs to be there as well? Neither piece was present when I disassembled my distributor tonight.

Re: More Distributor questions!

Keep your distributors pointless.
Keep my points distributorless.
Hope this helps...

Re: More Distributor questions!

From Dave Ray (IgnitionMan) earlier this morning,

"The plastic seal is GM part number 1950569. They should be about $1.20 or so each."

"The felt is shown in aftermarket parts books, like NAPA, CarQuest, Standard Motor Parts. Easiest to cut the felt from a sheet available from hobby stores."

"These seals and felt washers fit both points type and large cap vacuum advance HEI."

Regards,

Milton

Re: More Distributor questions!

In Vizard's book, he shows filling the grease well with grease and then putting the plastic seal over it topped off by the felt washer.

The grease well goes nowhere, it is just a cavity in the distributor housing so what is it's function?

Re: More Distributor questions!

If you're running points do over do it on the grease / oil. The lube can wind up between the point contacts and stop the engine from running. (Man you should have seen the hacked up wires from good simaritans trying to help).

The grease in that well under the plastic seal is the only lubrication the upper bushing sees; only the lower bushing sees direct engine oil splash lubrication. 9 times out of 10 when I tear down someone's 50's-60's Corvette distributor, the well is full of what looks like dried-up chocolate cake. Most folks have no idea that the well needs occasional cleaning/lubing.

Re: More Distributor questions!

Thanks John, we can always count on you for the best info on this site.

What I don't get is how the grease gets from the well to the upper bushing, I don't see a hole in the aluminum distributor body. I can't see a communication between the inside of the well and inner portion of the upper bushing.

I even cleaned the well out with a gun cleaning rod and nylon bristle brush. I re-used the original felt washer by cleaning it with dishwashing soap. Then I re-oiled it well before I put it back in. Hopefully, it will be fine.

Re: More Distributor questions!

My mission for tomorrow's lunch break is to go to Napa and get the plastic part and felt washer. If Napa doesn't have that part, who does one go to get a GM part? The dealership?

And per chance, if I end up at the dealers, part number on the felt washer?

thanks guys

Re: More Distributor questions!

The bushings are porous, and when the grease is heated by normal engine operating temperature, it liquifies to a semi-oil state, permeates the bushing, travels to the shaft, and lubes the shaft.

Milton
