Crash bar moumting

[SVSooke]

Got a 3 point crash bar off Ed(Nessism)for my 78 1000.I need a longer front engine mounting bolt.Put it up in the parts wanted http://www.thegsresources.com/_forum/showthread.php?237969-Front-engine-mount-bolt with no bites.Don't relish the idea of using all thread for this.Suggestions welcome.
Thanks!

Hey there. I tried to add a crash bar to my es and ran into the same problem. I was able to search the fische and find a longer bolt from another model, cannot remember exactly how I went about it, but.... The bolt sizes are coded into the parts numbers. Got the new bolt, tried to mount, and doh, the other engine mount bolts that the guard mount to are too short too! Guard is still sitting on my shelf, unmounted....
Sorry, I know this isn't too helpful....

I've found a couple of firms in the UK who sell M10 (standard pitch) x 300 bolts in A2 stainless. If you get really stuck, let me know, and I'll order one and forward it.

Yeah have enough other bolts that I shouldn't have that problem,with my 1000 all the other bolts minus they're washers look to be good

The 280 in the link would be prefect!Will hit up the local places first though.There really should be something I can find locally.Guess I could have thought of that earlier:witless:

 

[SVSooke]

Well the local(Sooke) parts place phoned the local(Victoria)fastener place,longest they had was 260mmDoubt I'll find one longer new in the area.The only cycle wrecker locally is only open at odd hoursJust remembered Kenco in Sooke,got to try there for sure:idea:At $6CAD and change Steveb's is tempting,just wondering what shipping will cost.Linked cost was 9.99 pounds.

 

[SVSooke]

Will hit my local dealer(Kenco) to see if he has one.If not the guy I use on eBay for SS bolts(http://www.ebay.ca/usr/northenmoi) might be able to get a black M10x280nn bolt.Failing that Steveb922 will work with me to get me a SS one from England.

IIRC, most of the crash bar kits back in the day actually came with a piece of all-thread with two washers and nuts. I'm not saying it's right, but it's authentic.

The GS850 used a beefier 12mm bolt, (your GS1000 used a 10mm bolt), but what I found when I bought the bike and found a missing nut was a piece of 1/2" all-thread... fine thread, just to ensure that I would not have a replacement nut on hand...

I would NOT use stainless steel here -- it's high strength, but brittle. I'd use a grade 10.9 or 12.9 bolt or all-thread.

 

[SVSooke]

Finding a M10 280mm long is turning into a nightmare,the local dealer had nothing close.I doubt I can find a 10,9 or 12.9 bolt this size.The local auto parts place has hi tensile all thread,looks like a 3/8th piece of that will be the solution in the end.,as much as I HATE using standard threads on a metric bike:dread:

OK I keep reading not to use SS bolts for this.I'm not convinced,has anybody actually seen a SS bolt break when used for an engine bolt?With your own eyes I mean because it's starting to seem like an urban myth to me:-k

This.

All-thread is very strong, reasonably stiff, and easily acquired. For a motor mounting bolt, it is pretty ideal because it will "give" a tiny bit due to vibrations, but is strong enough not to break under the stress.

Several engine guard kits from back in the day that I've used (I always try to find engine guards for my bikes) came with all thread. Others came with replacement bolts, but they were made of plated ferrous material (like all thread), and most of them were not even metric bolt/nut sizes.

I can understand why you'd like to stick with the original design of the bike and use slightly longer bolts, but you'll not notice the difference using all thread, and it will solve your issues.

My bike has all an all thread for the mounts. I know the whole standard on a metric is annoying but hey how often will you remove it?

Yeah all thread would have worked OK but I'm taking Steveb922's offer and getting the 300mm stainless bolt.I forgot to post that

Greg, here's an option, 10.9 high strength Threaded Rod.

McMaster Car will sell only to companies I believe, but if it's not too late, you can use my company name and your mailing address.

$10.00 plus shipping (approx. $18) for a metre, you can make 3 bolts. and get the nuts and washers as well.

You'd have it by Wed if you ordered today.

Thanks David but it is to late,this time.Don't really need 3 bolts at this time either.If the offer to use your companies mane is open I may take you up on it!Lack of a company name has made McMaster and Carr a no go for me.

 

[Guest]

Go to a machine shop and have them make you a high strength steel bolt. That what I did on my swingarm pivot bolt, needed a 16mm about 3 inches longer, got it made no problem. Think it cost me $35.

Greg, you are welcome to use our company account, just phone the order in and give them your address as the ship to address.
Oh, and don't forget to give them "your" CC details
