091 coil

Re: 091 coil

Any idea where I can find those metal tabs that go into the pin holes and sit on the threaded post ?

Mark;
Years ago while looking through the inventory of an electrical supply house I came across some that were very similiar. The difference as I recall was in the long end that points out---a little too long. Unfortunatley I do not have them anymore. Maybe if you try electrical supply houses and the www you may be able to find them.

Good Luck!

Mark,

You may also try ebay for old coils as they may not be expensive and the doner parts you need may be there.

Interesting reply. In order to avoid the same plight do I simply disconnect the coil when working to test wipers, lights, etc....?

Nick -

Use the "Accessory" position on the ignition switch as noted on page 6 of your owner's manual - that position powers up everything except the coil.

"Any idea where I can find those metal tabs that go into the pin holes and sit on the threaded post?"

Visit a scrap yard or swap meet and pickup ANY Delco Remy coil from the 50's. It will NOT have the shoulders on the mounting tabs at the center tower and will have used the washers with the tangs to thwart the washer from spinning during torque down.

BUT, if you're looking for these washers for a coil that was built after the design change that added the shoulders to the mounting tabs, you're probably on a wild goose chase!

The Restorer Magazine article mentioned detailed the running changes and the story goes like this:

(1) 50's, no shoulders, holes in mounting pad & use of tanged washers.

(2) Circa 1962, added shoulders, left the holes in the mounting pad to be 'downward' compatible and moved to conventional washers without locking tangs.

(3) Circa 1967, reworked mold to remove holes in the mounting pad thereby eliminating downward compatibility with earlier tanged washers. You can see 'flash' on the pad where the holes used to be...

As of 1962-63, it's probably a coin flip as to which version of the washers were used based on on-hand inventory of tanged vs. non-tanged washers...

Re: 091 coil

I have a 091 that does not work properly, car starts and pops etc. Upon removing the screw and coil wire catch there is no oil inside. The bottom of the can is bugged out a bit and I remember it got hot when I tried to use it.

Is this trash or can I add oil and try over again. What type of oil is used in these coils. Any help is appreciated, If I put my ohm meter across the primary terminals the the needle deflects to no resistance. If I put ohm meter terminals from primary + or - to secondary the needle does not move. Thanks for the suggestions, Tim

Correction, If I put ohm meter from secondary to primary + or - I have approx 9500 ohms.

Tim, I am certian this is partly because I am anal (or a null as my wife says) but I would keep the coil, as I do most of my old and inoperative stuff for history sake and a future break through in rebuilding.

Re: 091 coil

Steven,

I am not going to get rid of this coil. I just want to fill it up with the correct oil and try it again. I realize the coil will probably not work properly but I want to try.

I believe it's the correct configuration for my 63. Can anyone tell me what kind of oil to use in this coil?

Re: 091 coil to Tim and Rick

Dave, I remember the article on the 091's. My 63 had an original 091 coil and it was embossed near the bottom. It would be really neat to find an original with the 091 embossed near the top. I heard they existed but have never seen one. John

Re: 091 coil

Darn! I pitched a lot of old ignition parts including coils on our last move here to Florida. Guess I should have put them in cryogenic storage for my Heirs to deal with. I kept my Mallory Magspark though.

Still, Tim, you got my interest up. I'll check my parts bin and see what I did save. I've been into Electronic Ignitions for so long now that I got rid of most points related stuff - except about a half dozen point sets for old times sake. I know I also have one more Dyna-Flite ball bearing plate (love those).

Tim, I believe the oil for the coil is the same as the oil encasing transformer coils. It is mineral oil. I am uncertain if it is the same or similiar to the drug store variety.

Re: 091 coil

Thanks Steve, I'll check it out.. I am going to fill and try it again just to make sure..

Re: 091 coil

Clem your verification of the hazard of the oil reminds me of being told about how much it has cost government to replace the old oil filled transformers and have the contents destroyed. If I remember correctly there were only two locations in the US that were licensed/capable to destroy the oil.

the CRS "can't remember s--t" was referring to my memory not the oil.

the oils in question were "PCB" that caused the cancer

Re: 091 coil

Does anyone know the correct resistance of an operable 091?

Re: 091 coil

John, My memory from the 63 shop manual is primary= 1.4 ohms and secondary is 8500-10500 ohms. I will double check later and post if this is not correct. Mine checks out and worked but got hot fast and started acting bad, turns out no oil but I am fairly confident it's wore out.
