HELP! Identify this Bolt and Nut?? Ninja 2006 Ex250

Hey guys,
sorry to bother everyone with such a silly question. But, does anyone know what bolt this is. . .

I noticed that this bolt that is missing a Nut or Something to secure it it on the other end?? It looks like the bolt goes from the Left side to the right and through the top of the Crankase & attaches to the Frame near the top of the Suspension attachment-- But, I cant locate a part for it on the Kawasaki parts Diagrams?

If anyone can shoot me a photo of what it looks like on the side that is missing the nut,. . or tell me what bolt this is, . .that would be really great!!!

Thanks in advance. . . Ray-

Hi Ray, welcome to Ninjette!

That long bolt holds engine to frame. Better get nut on there ASAP.

I think you'll find it in the Engine Mount section.
https://www.ronayers.com/oemparts/a/...1/engine-mount

Can also get M10x1.25 nut at hardware-store.

That's fairly common with the Ninjas.

I would use some blue threadlocker on the nut when you install it.

The factory nut with a shoulder would be the best. If you use something else you should use a flat washer under it.

Hey Jay,
Thanks for the tip!
I'm curious though, Does the threads of the bolt stick out a lot when the Nut is put on and tightened down? It looks like there is a lot of thread on that side of the bolt. . .

I don't have one here to look at, but most likely there will be a bit of threads sticking out past the nut.

Pretty sure the original nut is shouldered or there may be a large thick washer used. There is also a torque spec for it. I'd get an original nut/washer, some blue threadlocker, and a torque wrench. It would be a good idea to torque other critical bolts that may have come loose as well.

Yeah, that's a great idea!

So, searching through the parts diagrams- it looks like this is what the nut looks like. Its not showing a washer, but the nut is flanged,

They are calling it a NUT,LOCK,FLANGED,10MM. Part No. 92210-1080

Good idea to threadlock and torque it! I just bought the bike a few months ago, and was riding around with this bolt hanging out!!! Not gonna do that again. .

That's the one, so it's flanged and may have some type of locking mechanism - which is odd because they vibrate loose. Even if it does, some blue threadlocker isn't going to hurt.

Yep, they sure do vibrate loose. I was hearing a jangling noise under my seat for a few weeks, . .thought it was maybe it was the cam chain tensioner? But, when I looked almost the entire bolt was hanging out! if not for the bolt hitting against the cover of the Front Sprocket cover, . .that bolt would have been long gone! lol

Anyway, will definitely put some blue threadlocker on this sucker!
Thanks for the input!

"Lock" nuts don't necessarily hold like one would think. I had a couple engine mount bolts vibrate loose, too. I painted a mark on them now so I can look at it and make sure they're behaving.

The saga continues. . . .

I had NO Idea!! That these engine bolts were so susceptible to loosening from vibration!???

The saga continues, . .I decided to get motivated and clean and lube my chain- so I removed the front sprocket to clean. . .And noticed that the lower Engine bolt had almost completely wiggled out- without the nut- Again if not for the frame holding that long bolt it would have been gone!

Anyway, I ordered the proper replacement bolt, some lock tight, and Hi-vis Torque paste- the same stuff we use on some of the helicopter thread and bolts, . . so that I can easily check them!


Does anyone know the Torque value in Lbs for these Engine Bolts?

This is what I've found - https://faq.ninja250.org/wiki/Checki...ne_mount_bolts

"Engine mount bolts are one thing that will loosen up with time and vibration. This can happen in as little as 7500 miles, so it would be a good idea to check the torque a couple times a year, or at least as part of the winterization process. You should also check the other fasteners periodically, too.

There are only 3 mount bolts, and they all have a torque value of 24 ft-lbs and use a 14mm socket. There are two at the rear and one at the front of the engine. Use red (high-strength) thread locking compound on these bolts to prevent them from loosening again so quickly, although since you'll probably be pulling the front one when you adjust the valves, just use blue Loctite on that one.

The rear two bolts both have nuts on them. The nuts are located on the right side of the bike.
"

They suggest Red threadlocker, but Blue (medium) is usually adequate. I like the gel/paste compound instead of the liquid.

What's really odd is that's very low torque for 10mm fastener. Resulting in little tension on bolt, and little friction to hold it together. I really like these lockwashers.

I was just going to ask , . .Do you think it might be worth putting a split washer or one of those (wedge-lock washers) on the bolt??

That is rather low for a bolt/nut that size. Another source gave the same spec - 32Nm or right about 24 ftlbs.

With ample medium threadlocker you should be fine, but a locking washer of some type isn't a bad idea.

Once we torqued mine to spec, I haven't had further problems with them loosening again. A locking washer might not be a bad idea, though.

Isn't red loc-tite the permanent one? I'd use blue.

Yes. It usually requires heat to remove and is not normally used on anything you may ever want to remove.

Blue threadlocker should be adequate.

I haven't had any issues on my street bike with blue Loctite and serrated flange nut. But on my race bike, I've had to retorque those engine bolts every month! So I went with one drop of red Loctite, Nord-lock washer and distorted-thread flange locking nut. Haven't had any issues in past 2-years. Can actually loosen nut with breaker-bar since one drop of red isn't very permanent.

Reason torque is so low is because of mounting-ears on engine. Too much will squeeze them together and break them off engine. Now, if they had spacer-tube in between ears like between hub-bearings, then we'd be able to crank them up to proper 47-lb*ft torque for that 10mm bolt.
