What is the crank arm bolt size if I want to purchase the bolts seperately ?

Crank arm bolts are a standard size, and any bike shop should carry them. I'm not sure of the thread pitch or bolt size. Another really important thing to know is that the bolts are hardened to allow extreme torque for pulling the crank onto the taper. If you use an inferior bolt you will have troubles keeping the crank on. The Botom Bracket should have come with a spec sheet, if not go online and look up the torque specs. ...hope this helps you.

Yes. The crank arm length is about personal preference and/or your height. Shorter crank means more clearance. Taller frames usually have 175 mm cranks. Most people won't notice the difference.

A 2 1/2 to 3 in. lag bolt works great. I used a washer as well, but probably not necessary. Have fun!

Check the crank manufacturer specs for pedal spindle diameter compatibility.

My handlebar on my 82 Honda Silverwing is 1 inch, and the u-bolt had room to spare on each side. I believe the u bolt can go as big as 1.25 inches.

I was able to make them work for me but I don't have the same bolts you do. Sorry can't be of more help.

It came with the bolts for installation. However I used 2 of those bolts and 2 that I had left when I took off the old hand crank model I had. Wasn't the easiest job wiring the thing and if I had to do all over again I would take it to a mechanic that specialized in mechanics.

Actually is the round exagonal head bolt that holds the crankarm to the BB.Usually an 8 mm hex head that pushes the arm into the square tapered bb.

Hi Mary, I think you need one that is specified for a 3 piece crank. Search 3 piece bottom bracket which Amazon displays and you should find the correct one. Research you bike model referencing the crank as well. Hope this helps. Greg

Yes, I forgot what sized bolts were included( if any, I actually forgot) but you could just buy the correct size bolt for whatever size plywood your bolting it too.

Can't find the specs but it almost certainly will work. Almost all older mtb cranks are the same bolt circle diameter.

The 175mm is just the crank arm length. A crankset includes chain rings, bb, crank arms. If you don't need a set just look for the chain rings. Make sure they are correct though.

It's a machine bolt and you may not be able to find exact head. Any Ace Hardware should have a similar bolt/screw. If you bring one of the remaining bolts for an example is best if not ask for a quarter 20, 1/4 inch wide by 1 3/4 inch long machine bolt. Good luck it should be easy to find. ACD

It's been almost a year so I don't really remember. I don't think there were instructions but there aren't that many pieces and I think all the bolts are the same size. I thing every piece had it's own place to fit and not much confusion on where it fit. Sorry I can't be more help.

Not sure. Mine came with the bolts. They looked like 3/8 from memory though. Hope this helps

So here it goes: the bolts dimension is 3 7/8 inches (a fraction bigger) by 1 1/4 inches height. The "connecting part" for lack of a better name is 5/8 inches of width (a fraction less) and 1 3/8 of height. I hope it helps.
