Title: HELP! I need a m7 x .8 Tap! Any Harley Guys?
Post by: 38flattie on April 03, 2013, 04:44:19 PM

Don is working like crazy to get the lifters done. We are using early Harley adjustors, and just found out the take a m7 x .8 Tap!

If anyone has one they are willing to sell, or knows where I can get one ASAP, it would be much appreciated!

Wow! new fenders and tires.

looked through my hog taps and dies - nothing.
do you know what it was used for ?

called my machinist~~
      he found it online at-
   production tool on Brookpark Road in Cleveland
         and at-
    Msc Industrial ( Industries ? ) in Detroit

out of the yellow pages- production tool supply of Ohio -216-265-0000

I hope this helps you out.

Local mac, matco or snapon dealer have it? Maybe as part of a large tap and die set. Any bolt and tool places near you?
Grainger?
I will look in my mac tap set when I get home and see if I can get you a part number.

KBC Tools has a really good stock of really odd taps and dies. They're probably your best bet. When you order the tap get them to send you a catalog too. It's phone book sized. They have lots of stuff you never knew existed.

Are you sure that they're actually metric? Harley had a lot of their own bolts with odd threads in the earlier models.

I have one here but it will probably take a week to reach you. Do you need the bolts that match?. Let me know. Mike.

  It is a 9/32 - 32   dam close to .8 pitch --  I did the cardinal sin " assumed " metric after I put the calipers to it. I re-checked it this morning with the mic. and a 32 pitch gauge.     Thanks for the input guys !!!!!!!!

The lifter adjustors I have were from 45's and K models. The same basic adjustor, or at least the thread, was used 1915-1984= Singles, Knucks, Pans, Shovels, O.H.V. 45’s, Sportster and K models........"

No possible way that any good Amurican bike, especially a Harlem F-ing Davidson, would have any of that commie metric thread stuff on it!! I believe 9/32-32 but 7mmx.8, nfw!!

Unfortunately, Harley has gone a bit "Commie" as you say.... the newer bikes have A LOT of metric stuff - starting with things like 39mm or 41mm diameter fork tubes .... think of all of the other ramifications from JUST THAT ONE!

Also, quite a lot of smaller items have beeb "discovered" as being metric.....

That's cause a "lot" of their parts are being outsourced to companies in China.  A few years back a company in Australia that made several HD parts had a labor dispute and lost HD business, those parts plus a lot of others started being machined in China.

New(er) Stuff. . . . yes, metric sizes and threads.     I believe it's called a "world market". . . . .  which really means: our jobs went to China (or wherever. . .) people are willing to work for slave wages. . . . . . .

Older Harley Stuff (Pre 1980 ish)  metric. . . .   NFW                    ALL: UNC; UNF; & UNS (as in 9/32 dia. x 32 tpi) threads & threadforms. . . . . .

Harley Davidson used 1/4 24 thread on tappet block and transmission covers for many years. I believe the last year for the 1/4 24 was on the 1975 shovelhead tappet block holes when they quit making the countersunk tappet blocks.

By this point Buddy has built a new car!  :-D

Tap was an SAE size if you read Pops mistake.
