Good question, you may be able to determine where it goes by the quantity of the the bolts. Is there only one, or is there more of the same?
 
Never saw one like it on a 1930 Model A.

Head thickness vs. small diameter of bolt & short length of threads appears to be structurally out of proportion for cost effective mass produced bolts.
 
Not knowing the year of your car, my guess would be that because there is only one, that it would be the bolt that holds the adjustment ******** the powerhouse generator. This would mean your car would be a 28.
 
Hi,

Just a thought - bolt that holds generator pulley to Powerhouse Generator??

I just serviced mine, and the center pulley bolt was 1/2".

What does the FILLER PLUG look like on a shock absorber?
Is it square or hex?
This thing reminds me of a filler plug, but I think the filler plug is square.
 
There is an excellent article in the "Restorer" mag. from May/June 2012 on shock absorbers written by Steve Schmauch in Spokane, WA There were 4 designs of filler pluges used. 3 different ones from 1927 through Jan 1928. Starting with a slotted type then to a 1/8" square pipe plug type and then to a flat hex plug. Thereafter the filler was a 7/16" square headed pipe plug. Hope that helps.

I looked in Steve's book, there all 1/8" pipe, also...unless I missed them,
I didn't see any "hex", but I was looking quickly. Gez...maybe the darn
thing isn't A....you guy's helped....but what doe's it fit. Thanks
 
A-20937........3/8 -24 x 9/16 hex. hd. bolt is what holds the 1928 powerhouse adjustment strap to the generator bracket.

The 2 special bolts for the pulley and armature have a shoulder and are 1/4 x 28 thread.

I don't know what this bolt is for either. :confused:
If it was a little longer, I could use it for the missing bolt for the crank cover for my 1 1/2 H.P. Hercules stationary engine.:)
 
No answer but to add to the mystery I have a bolt that looks like that but a little longer saw it the other day when installing my engine. It was in the bell housing to flywheel housing connection. I thought it looked strange but since it came out and fit fine I put it back in.

D.J, don't you mean it's drivin' you "BOLTS"?:p I didn't put it in your box to confuse you! In my SORRID past, I have added a strange bolt/part to some guy's disassembled unit on his bench. Once when disassembling a Dodge Colt carb, a 3/8" steel ball fell out, took awhile to figger out that one!!!:confused: Willy Bill
 
D.J. take a look at the article Steve wrote in the "Restorer". I almost copied the words out of the article which is complete with photos. He did the research for the Judgeing guildline group.
 
showerxpert,

Well,...I looked last night. Steve sure has updated that section, a lot more
information and photos, just for the Houdaille's!

But, back to the bolt....it's not pipe, not from the shocks. I'm not giving up,
I'm just not going to worry about it....till I remember!

Thanks guy's, Dudley
 
I agree with Ron C. Looks like the short bolt on a T engine which holds cam bearing in place.
