What are these bolts...?

[SteveR]

Yes, I know I'm being lazy, a little Google, or even flipping through the service manual over a cuppa would probably answer my questions, but I'm feeling a little frustrated with a string of little things going wrong with the bike, so I'm after the soothing words of an expert as much as I am an answer :P

This picture was taken looking in through the left access, that's the rocker cover on the right, radiator on the left, what are the two large bolts in centre screen? I'm presuming structural...?

Front subframe mounting bolts, there are two on the opposite side as well as four or six(cant quite remember) along the frame.

This might give you a better idea. I think this is removed should you need to remove the engine from the bike.

Item 4 in the image. Two bolts as in your pic on the LH side. One on the RH directly opposite and one on the main frame behind the LH engine guard (wing).

[SteveR]

Righto, so I would be right to presume they should probably have nuts on the back of them, and not just be floating around freely?!!

[alans1100]

Two options re the bolts. Bolt plus nuts or bolt plus nut welded to frame. Bit hard to tell from the parts fiche but the manual shows nuts should be there.

[SteveR]

...but the manual shows nuts should be there.

One would expect common sense to agree also!

Perfect, thank you... now for my next dilemma... Presuming they are supposed to secured, I tried to get one out to take to a local nut'n'bolt place, but the buggers won't come out!  They spin round & round without taking up a thread, and move in and out maybe a couple mm, but no more... So... Does anyone know the diameter/thread gauge?

If you can find your bolts in this diagram   http://www.ronayers.com/oemparts/a/hon/506c1862f870023420a2ea6d/frame   you will find that alongside the part listing is a number in a bracket (eg  8x20) which would be the metric bolt size and length.   The  cited example of 8x20  would refer to a  M8 threaded bolt which is 20mm long.    Armed with that info you should be able to buy what you need from your local fastener supplier.

Might pay to get new bolts as well

Item 34 BOLT, FLANGE (10X50) 95701-10050-07

The nut is a bit more elusive but from the manual it's a flange nut it looks like Item 21 NUT, U (10MM) (FUSE RASHI) 90304-GE8-003

[STeveo]

These are 10mm fine, ie 10mm dia x 1.25mm pitch.

Just had a look at Blue City Motorcycles http://www.bluecitymotorcycles.com.au/home

New Bolt part number is 95701-10050-00 @ $2.21 each
The nut is priced @ $4.71 each

Don't know what the pitch is as it's not listed but not important if you replace both bolts and get nuts to match.

[Wombat]

I can take mine apart but the diagrams show a seperate nut so they are not fixed. Need a spanner on the nut as well to get it apart
Cheers

Thanks for the link, I've ordered a couple of each, I thought that would be much easier than trying to find a match at the bolt shop, just go the real deal! Hopefully, in the pre-Christmas rush, their turnaround is quick, so I can get this underway before I'm meant to be on the road.

Bolts & nuts arrived today!    Now to get the old ones out... hmmm....

[SteveR]

hmmm... can't get the old buggers to budge, thinking I'll clean up the threads as best as I can and stick the new nylock nuts on the existing bolts.

NYET !       To the nylock nuts ! (just my humble opinion)

I had reason to separate those parts on my '96 ST1100 some years ago. Pulled it apart for some reason, timing belt, water pump or something else - then went out and purchased a workshop manual - live and learn !

Being an old f*rt, and following the old fashioned ways, any / all high tensile nuts and bolts, once undone, get thrown straight in the bin and brand new high tensile nuts and bolts of the exact same size are purchased then used.

I've been doing that for the past 40 plus years on all my bike and never had a replaced nut or bolt fail on me (YET)



 

Flip.

Hmmm, what you're saying makes sense, but I was hoping I'd be safe, as these are the gen-you-wine, OEM bits... When I ordered using the original part numbers, there was a note saying the nut had been superseded  and it gave me the upgraded part number, which is this nylock one... I can't imagine Honda 'upgrading' to something less safe?? Hmmm... You've got me thinking now...

[West Aussie Glen]

I don't have any problems with Nyloc nuts nor have I ever thrown any hi tensile bolts away after one use unless they were in very specialized applications.
SteveR looking at the photo of your bolts there has been a lot of movement and wear, almost looks like there could be shoulders worn on the bolts stopping them from coming out, you may need to juggle the parts to get the bolts to move. I would definitely be replacing them.

Well, my son has just gone back to his mums place after we had an early, boys Christmas, so now I'm out to the shed... I'll see if I can find something to use as a long drift and see if I can 'persuade' them from the other side...

[StinkyPete]

Can the nuts be "persuaded" to come free from the frame by loosening the bolts a couple of turns and then giving the bolt heads a tap? (or have I misinterpreted what is stuck)

I think you may have... There are NO nuts, at all!

Any success in removing the bolts yet?

[Grumpy]

A bottle jack under the frame with gentle lift may persuade them to come out.

I've been a bit recluse over the past week or so (never have been a big fan of this time of year), so I'm sorry I haven't reported back earlier.  I got a call from Greencan just before Christmas offering some great advice, I need to get back in touch with him again actually... anyway, short story is that I was struggling a bit to get the old bolts out, and feeling a bit low on the mental power to persist, I managed to get the new nuts on the end of the existing bolts and torque them up.  On closer inspection (i.e. opening the bags and actually looking at the nuts!) they aren't nylock, they just have an attached lock washer on the outer side.  Anyway, I figured that, even if I can't replace the bolts right now, at least having the nuts on there is better than nothing.  Greencan offered a hand in the new year, so I'm going to get in touch with him to get an experts hand in making sure it's all as it should be.
