Fastener cross reference from the parts manual?

[Donkey Hotey]

I'm finally (finally!) putting 1525 back together. This month is fifteen years since I bought her. This fall will be fifteen years that she would have been in pieces (cracked head and--later--a camshaft damaged in the storage box waiting for the head).

Tonight, I went through all the fastener and hardware in the boxes. I'm sorting through basically everything that would be removed to take off both heads in the frame. I've identified nearly all the fasteners (400 of them seem to hold the valve covers in place  ). I have a few left that I'm sure will eventually identify themselves.

My question: in a lot of parts manuals, common hardware has a cross reference in the back. Has any such thing been released for our bikes? It would help if I knew that I needed to find a quantity of eight 10-24, black socket head cap screws, rather than trying to identify them from where they go and the approximate grip length.

She will soon roll again.

You can happily size and reference about everything you might need to find replacements for.  It can be very time consuming, and it takes a bit of practice and a lot of attention to detail to make sure you get it right.  I haven't yet found a 'PERFECT' bolt and fastener source to get special titanium fasteners for various applications, but it's very likely that nearly every bolt is available even in aircraft or Air/space spec.

I don't have my bolting books on me right now, but I plan on getting an ICC bolting certification within the year. 

If you go into your nearest Fastenal, usually the guys are helpful enough to go through some of the techniques of getting measurements right when sizing your bolts, and can usually reference the hardness and quality of what you need.

They're pretty good at ordering something they don't have, but I'm sure there are better sources out there.

Cheers and good luck!

Thanks for that but, I'm not looking to buy fasteners. If I have two fasteners and they are identical in every way except one is 1/8" longer than the other, it would be nice to know which one goes where.

I was able to count out all the higher quantity fasteners and narrow by process of elimination: 26 black oxide screws: OK, those go on the valve covers, etc, etc, until I have leftovers.

I don't want to button up a 5/8 screw inside the engine and later learn that the leftover 1/2" is 1/8" too short for the hole remaining. Knowing the designed fastener length and type would prevent that. Right now, I have to find both fastener locations and try to reverse-engineer why one is longer than the other.

Still just love the R/Os..... make me smile..
Other than the service manual/parts with the blow up shots.... I dont know of any  other sources. And to be frank, those blow ups work pretty good...

Chad a sidenote:
As a hobbiest... I love mcmasterkarr for bolts/fasteners. Nice priced and terrific service..

Great Link, Bruce.   I wish I was able to help look for the bolts you need, especially if I need them too at some point in time. Donkey

Hmm...well...I spent all afternoon sorting fasteners.

I have (20) 1/4 x 0.75 that are supposed to go to the valve covers. From the manual, i should have a quantity of (26) (13 each). I only have (20). When I count the flange heights, there should only be (12) of the shorter screws per cover. At least one that was counted as a short was actually a long grip (1.0).

I also have (16) 1/4 x 1.0. According to the parts manual, there should only be four of those per head for a total of eight. That leaves me a surplus of 8 fasteners. That leads me to believe the head was assembled with some of the longer length in the wrong holes and the remaining eight still go somewhere else. While I could have reasonable lost some screws in 15 years, I certainly didn't inherit additional EH screws in that same time.

I only disassembled one engine (both heads and cylinders, scavenge pump and timing case opened). All of these fasteners are stamped EH. My new cylinder head is new (no screws except the eight holding the cam caps). I bought no other fasteners.

The timing case, scavenge pump cover and pump screws are all accounted for and bagged with their parts.

I can't make sense of this, except to assume the longer screws were used in random spots on my valve covers. I measure almost every one of the holes to be deeper than 1.1" with the cover flange in place. I've already tried and it snugs up fine, regardless of grip length.

Greg,
  You might give Jamie Jones at Atlantic EH a call. He knows these engines so well, he could probably shed some light on your situation in short time. 540 298 9310.

There is a list of torque values and placement location and quantity ...send me your email and i'll send ya the list ...  rcsandruck@msn.com   or  4437830920

Annnddd...that was indeed a fastener cross reference list. It listed a total count per bike and the dimensions. Very useful. Thank you, Bob!

Looking at it a little more closely, it lists the same quantity as the parts book for the cam covers. So my bike still has the wrong screws in it. Oh well, it'll work.

It sounds crazy but, I'm big on not having leftover parts when I put something together. It all came out of that engine, it should all go back in that engine.

Finally found a solid answer for not only fasteners but, O rings and other standard hardware!

Right here on this site:

Yes, the original Bill of Materials to build the bike. Much of the hardware is listed by its generic part description AND EH part number.
