'86 250SX rear hub

[Sawfly]

barnett - i've followed your instructions pretty much to the letter as far as using the puller and still no dice, we'll be trying the "non watch makers" idea tomorrow sometime... i'm gonna go ahead and get my last rites out of the way tonight.

dirtcrasher - i'm aware of the o-ring, do you know if it can be replaced with just a standard o-ring the same size?

Hello Sawfly and Up-tyte

Barnett - i've followed your instructions pretty much to the letter as far as using the puller and still no dice,

Again all I can say is I wish it wasn’t so hard to get off and that if someone had a better idea they certainly would have mentioned it by now.

we'll be trying the "non watch makers" idea tomorrow sometime...

Yeah, ya might get just a bit more leverage with that one, lol.

i'm gonna go ahead and get my last rites out of the way tonight.

Ok, but please keep in mind, this can be HAZARDOUS, although I’ve never had a problem. The only reason I even mentioned it to you guys is because up-tyte mentioned he has quite a bit of experience pulling heavy flywheels etc so I figured he would know the risks involved in using this method and take the proper precautions.

I figured I’d answer this for you only in case you get to heating your hub before he gets back. It’s actually a seal on yours, the size is 20 mm id x 28 mm od x 2.5 mm thick. It is available from the OEM parts suppliers below and probably Ebay. Just enter the p/n and ebay in the search engine.

if needed, I add some heat and bang to the center threaded rod, more pressure, hit it again.

Ok, now you have a “majority” consensus. Get the torch out, lol.

Hello MR.Barnett You did clearly say a 3" (inch) breaker bar and then in your usual cocky way of an explanation you said 1" breaker bar with a 2" pipe. Wouldn't that be 3"? not for publication.

I’m a bit baffled as to the purpose of this persons comments or exactly how they relate to your original question and subsequently how it has anything to do with helping you with your problem, but maybe you can make some sense or logic out of it.


Good Luck

I remember reading they only come out from one side of the bike. maybe your going the wrong way?.. I'm a horrible mechanic tho.!lol

[Sawfly]

so barnett, we ended up having to heat it to a nice glowing red, not bright red but we're getting there. then breaker bar and we had to reheat it. eventually came off with much groaning and popping. there's roughly an inch to an inch and a half wide solid rust ring around the outside of the splines(would post pics but the air was gettin to me). so i'm guessing the outer hub seal was either bad at some point or the right side sat in standing water for a couple weeks/months/years. melted and burned most of the seals on the hub and turned the lock ring white(hooray ash!)

i expect to get to work early-ish tomorrow. also, the flange/lugs are now bent due to the forces applied, while i will try to repair them i'm going to try and find a spare hub.

Killbot- the axle(from what i gather from the manual) comes out from left-right. hubs are separate

Hello sawfly and up-tyte



First, im glad no one got hurt removing your hub i warned you it was dangerous, second im glad you successfully removed it without having to CUT it off.

I’m just guessing from your comments and the way they are worded that you are less than ecstatic you got your hub off and still have an axle left. Most people in your position would at least be extremely happy it came off at all if not somewhat happy for those that took the time to read your post and offer you suggestions that ultimately led to it’s removal.

I forewarned you in an earlier reply that it sounded like it was stuck so bad it would probably break during removal or that if you heated it until it was "cherry" red like I suggested you should buy a new one anyway. Well you heated it up red but not as red as I suggested and you bent it and now you are unhappy about it and want to fix a bent rusty hub with no temper left in it because you had to heat it until it was red hot to get it off.

If you knowingly heated it less than I suggested in an attempt to have your cake and eat it too it would make no sense to be unhappy with anyone other than yourself, besides it’s not mine or anyone else’s fault that offered you suggestions on how to remove your hub which was rusted to the axle due to someone’s neglect.

Heat till it’s cherry red then use the “non watch makers” breaker bar and pray. If it fails rent the cut off wheel.

There actually is a science and skill to doing this when things are stuck as bad as yours is. You may break the hub because it is stuck so bad, if so don’t blame us.

That’s close but not EXACTLY what I suggested you do. You guys own a torch so I “guessed you know the difference between the two. Had you heated until it was Cherry red it would have come off easier and you therefore might NOT have bent your hub.

i will try to repair them

I told you it would be JUNK once you got it red hot so WHY in the world are you trying to save it? IT IS AN UNSAFE HUB NOW, USE AT YOUR OWN PERIL!

i'm going to try and find a spare hub.

I already gave you a couple suggestions how to do this, one of which was to post a request for one here in the “NEW MEMBER FORUM” but you haven’t done that yet for some reason yet you had the time to reply to inform us that your hub is bent and some parts are melted.

melted and burned most of the seals on the hub and turned the lock ring white(hooray ash!

You sound totally surprised yet you guys own an oxy/acetylene torch. Haven’t you used it enough to know what it does to metal that gets glowing red hot not to mention rubber parts?

[Dirtcrasher]

I was worried about his drum seal, not the hub seal.

Hello dirtcrasher


I saw that in your earlier post which was a good consideration so I looked up the rubber drum cover seal and the metal lock ring seal sleeve drum seal cover thingy and posted where he could get NOS ones. Besides I think that became the least of his problems since his hub wasn't going to come off unless he heated it unless he sawed it off and took a risk of damaging the axle splines. Since he sounded like he really didn't want to cut it off, this was the only other option I could think of. Like I mentioned, they own an oxy/acetylene torch so they made their own well informed decision.

[Sawfly]

well informed might be giving me a little too much credit, also, my posts are normally made to be viewed in a less serious and more sarcastically/with a grain of salt than anything else.

i try to fix almost everything, the temper hasn't come out of the hub to the extent that i believe it to be dangerous. i could be wrong but that's why i've got a helmet right? right. just roll with it.

i'm actually very ecstatic about the hub actually coming off, even more so because there were no injuries.

the bending was mainly from the beginning before we heated it and before i posted on here. the bending played a major role in asking for help.

i'm also going to sort through all the spare parts mixed in boxes that are sitting around the garage/shop/storage shed before i go looking to buy a hub. this may take a while.

and finally, dirtcrasher - the outer drum seal is gone although i still have the spring which i will throw in a useless box of odds and ends for some random project.

Barnett says it's available. The o-ring in the hub was just another improvement Honda made to keep water out of the differential once it made it's way past the swinger tube. The 85 seals like garbage. I would tear that whole thing down, clean it, silicone up all the joints as well as the boot and use "open gear compound" on every spline. You can't get this grease off your hands, it will take a few showers

Water is a terrible enemy to trikes; But we all use them for different reasons. The best thing you can do is preventative maintenance.

I had an 85 that the diff ring gear holder was about to strip from water and rust entry. I sold it............

[Sawfly]

i use cheapcycleparts for referencing part numbers and i've found all the seals i need so i think that'll be fine. that entire rear end is getting taken apart, i've drained muddy oil out of that final drive enough that i'm gonna spend a little more to seal it a lot better(although my brake actually had very little real rust) i'm waiting to pull apart the diff till i get back from my 2 week reserve training. then i''ll finally see just how bad it's gotten.

i work as a mechanic so preventative maintenance is something i'm normally very good with but while i was stationed in CO this sat on a trailer outside with a tarp most days, it's also cold up there so there's only so much i could do.

[Dirtcrasher]

Careful with those diff caps too, they snap easy. Just grease it and snug it up.
