bolt length, dia and thread # on Ca77 dyno to r h crank shaf

Post by solarcycles1 » Sun Jan 27, 2008 10:42 pm

I need to know what size tap to clean out the right hand threaded crankshaft on a Ca77 1964 305 motor. I also need to replace the bolt, Part # 90026-259-000, If someone can tell the size of bolt, dia , and thread size, great!! This attaches the Dyno to this tapered rh crankshaft.

Dyno Bolt

SOlar,

The dyno bolt is an M8-1.25 bolt.

I got mine at Western Hills Honda.

Call and ask for Terry in Vintage parts.
