I was going to use the tranny bolts to put my spare block on my stand, but they're not even long enough to clear the brackets on the stand. I went to Home Depot, and the closest thing I could find was a 12mm X 1.75 thread, but that was too coarse. Then I was looking at the SAE fine thread stuff, and that looks like it'd match up alright, but they didn't have any in 1/2", which would be the closest thing to 12mm.:dunno:

Also, are flywheel bolts 14mm 12pt? I assumed they were, since the clutch bolts are 12mm 12pt, and my Helm's says the flywheel bolts are 2mm wider in diameter.

 

flywheel bolts are 17mm 12 pt bolts.

as for the engine stand i usually use a nut and a bolt that will fit through the hole in the block. motor mount bolts also work.

 

17mm, and I thought they were 10's on the clutch... Too tired to remember that...

 

you're right, i just checked. looks like I'm 0 for 2

 

I ran into the same problem this summer, I ended up just setting my engine on the ground after trying to find suitable thread material all over the place [I have one engine on the stand, but the stand was actually cut to let the bolts work]. Eventually I'll probably have a set of bolts made assuming I keep working with Hondas.

And yeah, flywheel bolts are 17mm, clutch is 10mm, both 12 pt.

 

Yah, my spare block has been sitting on my creeper for a week and a half. I don't mind leaving it there, since I can still move it around and I never really used the creeper anyway. However, the fact that I went thru the trouble of assembling my stand and now it's just taking up space does kinda bother me. I guess I'll just call around and ask for 12mm X 1.25 X whatever bolts.

 

Good luck, I think you need like 7" long and the higher the grade the better, no place I called local had them and I was on a tight schedule, maybe you will have better luck.

 

McMaster-Carr has the 12 x 1.25 bolts up to 80mm in length. But they sell them in packages of 50. They also have threaded rod in that size. One meter for $23.68.

 

motor mount bolts work....... we got more than a few layin around so thats what we use
