Honda 400ex: Broken Swingarm Bolt Repair

I broke the swingarm bolt on my 400ex. This is what I had to do to get my quad going again, and the kit I ordered from JE Honda to replace the damaged parts.
Leave a comment and let me know what you think of the new intro. The old was a little outdated.

Just did mine on my 400ex last night. The atv god was with me because the swing arm bolt came out with a tap of a hammer with one hit lol just got mine from JEhonda and what a difference these are! Luckily I’m local with him.

[@Jmoney92591]

Just did my 04 ltz, I took the nut off and used a impact both ways just spinning the bolt, I then got a threaded small piece of rebar and stuck it all the way thru I used nuts and washers and a metal socket and ratchet and popped it right out, mine wasn’t bad but had the swing arm off anyway and just like my carrier they had Oem Japan bearings from when it was made

Great Video! Mine Was not broken, so that was A Plus, but I needed to remove that bolt to get my engine out. That was A Pain! My Bearings look good, but I think I'm just going to use Factory parts, I might get the Bolt from JE Honda. Or I might just do like A Lot of others do, once a year remove the bolt and grease it all up.

Smart with the puler trick with the socket I feel stupid I took a Sawza to it

Just got a swingarm bolt out of a RM250 - this has to be the worst to get out on any bike. BEST thing to do on any of them buy it and take it apart and grease.

LOL I change my mind not thumbs down thumbs up I don't know why but that was really entertaining to watch

[@robertsanetta8335]

I need those bushings and that bolt..do you have info to purchase them? I have same problem

[@jellyayala7642]

I haded the same problem cut it with blowtorch right off im going to do the same thing to my pivot bolt

[@yafa5834]

I am currently having to drill out my entire swingarm bolt due to it being see used in the case, very bad design on Hondas part, I’ve tried literally everything else

[@Mudford]

Sorry. I know what your going through. Best of luck. Replace it with the greasable poly bushing/ bolt like I did, so you don’t have a problem with it ever again.

[@zacsingleton6853]

If the bolt isn't broken is it possible to thread it out

[@midnightgunner9465]

Thanks for great content. 👍

[@starlord872]

I also had to cut that bolt on my 400ex but its stuck in the engine block pretty good, did you have any problem with the bolt seized in the engine?

[@Mudford]

Not in the engine. It was seized everywhere else.

[@L_Inks]

Did you ever get it out if so how

[@alexgale1525]

I’m dealing with this exact issue on my 03 400ex. I have to cut the bolt to get the swing arm out but now I have the bolt stock in the case and it won’t budge at all, any tips on how you got yours out? Thanks

[@Mudford]

Sorry, mine came right out of the case. Mine wouldn’t budge in the swingarm. Just try to get penetrating oil in there. Mine just had the bolt going through rubber or plastic in the case. There wasn’t any metal bushing.

[@nathanscott5158]

How many races did you get on those bushings, before needing to be replaced? * Plastic bushings *

[@Mudford]

I’m on the second season. I think the key is to keep them greased through the bolt. If they start showing wear, I can order another set. I’m not sure what the exact material is, I used plastic as a generic term.

@@Mudford Bushings still holding up? How many hours would you say you put on since installing them?

[@brad7718]

I see you are a fan of VGG as well. Lol

[@Mudford]

I met him at Rocky Mountain Race Week in 2021. We pitted by him and Doug Cook at a couple of the tracks.

[@sycoclan2130]

What deill but did you use to bore out the swingarm?????

[@Mudford]

It was a stone I had left from a kit for porting cylinder heads.
