I have searched EVERYWHERE !! and i cannot find !!
can someone PLEASE tell me the thread pitch size for a crankshaft pulley bolt on a 94 civic??
thanks!!

 

I know what you want to do, and don't do it. Get an OEM bolt.

 

Try a hardware store bolt, you'll be posting a thread like this.

thanks for the help! but acually the thread in the crankshaft is stripped not the bolt itself i just need to know the size so i can run a tap/dye through it i just need the exact metric pitch size i cant find it anywhere online

 

hello,i was browsing the site for help and found your post,i have the same problem,the thread in the hole is strip,and i need to know the size to re-tap.did you find out and if you did,please can you tell me what drill size and what tap size did u used,also did you had to get a bigger bolt.my is a 1992 civic dx.92-95 use same part.please if you can help email me at rondonlaurel@aol.com
thanks

 

For the stock engine, the bolt is 14 mm nominal diameter x 1.25 mm pitch. However, I am not sure you will be able to find a tap for this. The normal pitch of a 14 mm metric bolt is 2 mm (coarse) and 1.5 mm (fine). Some Honda literature refers to the crankshaft pulley bolt as a "special bolt" because of the super fine pitch it uses. I think the super fine pitch is why this bolt is so hard to free. Enmeshing occurs.

 

No offense...but how in the world can someone mess up the threads of a crank? Never mind...I guess that's what happens when lazy folks try to install the crank pulley bolt with an airgun and end up cross-threading the bolt and the threads.
