How to tell bolt size

[Trader]

The parts manual just says "bolt"

Can I cross reference somewhere to see What size a bolt actually is?:confused24:

 

Like right now I need to know what size banjo bolts to order to double up the front brake lines on the front master (88vr)

Steve,

 

In our Yamaha parts manuals, the part number designates the sizes of the bolts. Sorry that I don't remember what part of the number means what, but either someone will chip in or you can search the older posts. I know the explanation is around here somewhere!

For standard hardware type bolts the size is coded in the part number as dia and length but not the thread pitch. On the Banjo bolts the coding does not make sense as dia and length so it might just be a meaningless part number.

 

For example;

a 97026-06030-00 is a 6mm x 30mm long.

a 98706-04012-00 is a 4mm x 12mm long.

 

But then the banjo bolts are;

a 90401-10096-00 is a 10mm single banjo bolt but I know it is not 96mm (3.78 inches)long.

A 90401-10044-00 is a 10mm double banjo bolt and might actually be close to 44mm (1.73 inches) long.

I did mine some years ago, they are metric and not easy to find. think I got mine from Summit Racing. I may have a couple of leftovers,,, would that help?

Thanks for the offer Carl!

I just needed to know how to tell what size is needed for any application...and I got my answer.

This place is great...best $12 a year I ever invested

Metric bolts are measured, Diameter x thread width (peak to peak) x length. Example : 8mm x 1.25mm x 25mm. so measure

Every tool box should have a set of calipers and std. and metric thread pitch gauges. Not very expensive and very handy to have.

Does that mean that if it's in the tool box we need to know how to use them as well,,,, another steep learning curve!!!!
