Title: Rear Tire Change - not so freakin simple!
Post by weracerc on 08/16/11 at 05:34:43

Why - Is it that a thing that should be relatively simple turns in to the project from hell!.......I know a bunch of you guys have pulled the rear wheel off and change the tire or done the rear brakes and put it all back together without a single little problem......i unfortunately have not been so lucky......first the bag bracket bolt eats the new tire - so I have to take it all apart to get to the bolts and re-engineer the bracket mounting and install carriage bolts to provide max clearance for the tire (140/90)......then I try to install the tire by myself and find i need at least a 3rd hand  but really a 3rd & 4th hand.......so last night 4 days after the tires comes off the brake hub arm fractures while trying to install the tire :-/ "If it weren't for bad luck I'd have no luck at all".......today my welding buddy is going to try to repair the busted brake drum and tonight i plan to try for the 4th time with help to get the rear tire back on the bike, bags re-installed, exhaust back on it and hopefully be able to get back riding tomorrow......I wonder what the odds makers in Vegas would say about the likely-hood that i get r done today is? 1000 to 1 against...... >:( :-[

weracerc,
I feel for you. I just did a rear replacement, and didn't have much trouble, except I tried to get my spacers mixed up for a bit.
But from your post, and against what others have said, I am glad I chose not to go w/ the -90.

Using my Van to break down the bead, the old tire came off relatively easy, using tire irons....along w/ a rubber tire hammer and silicone for getting the last bead off.

The new dunlop was a lot heavier tire, and gave me a little challenge, but using my right foot only and the rubber hammer,....(no tire irons) and lotsa spray silicone, it went on quite well,......after I adheasive siliconed the spoke strip in place. But I had a little advantage in that I was working in a truck tire shop when I was 15 yrs old,......I learned a lot, and didn't forget it.
I would never asvise anyone w/o experience to change a MC tire themselves !
The broken brake arm,.....I just don't understand that, as the complete brake hub assy is removed first thing.

On edit, the belt hub fell out of the wheel,.....tried to hurt my foot !! ;D

yep the brake hub arm snapped in to two peices - it got twisted (torqued too much by my 'assistant" who got frustrated that the wheel was not going in easily and i was on the left side trying to hold the large spacer in place as the wheel was lifted on to the brake hub slot......just one thing after another.....going to re-position the bike on the lift tonight and try to make sure there are as few hopefully no obstructions to getting the wheel in quickly and efficiently.

i hear people say that alot - i used to be more mechanically indepent but stupid things from youth have caught up to me and my physical ability to use grasp, squeeze, hold, manipulate, work with hand tools etc has greatly deminished.......anyone who has done this by themselves my hat is off to you....anyone who has fought this trying to do it by themselve but figured out a better way i'd sure like to know what that better way is.

Post by Routy on 08/16/11 at 06:28:35

Am I right in thinking that the broken side is the "slack" side when braking ? If so, and if welding the alloy is hard to come by, a couple hose clamps mite work till a better way comes along ??

Title: Re: Rear Tire Change - not so freakin simple!
Post by weracerc on 08/16/11 at 06:39:07

yep the bottom 1/2 is broke off - my TIG welding genious here at work thinks he can get it solid becase of all the webbing structure behind the broken area....I ordered a replacement last night $25 delivered ebay from a 1997 with right at 11K miles (mine 96 with 11K)....it will be here in less than a week - but if it can be welded/repaired and SAFE i will try it.

http://p1.bikepics.com/2011/08/16/bikepics-2257696-800.jpg

hold on a minute - i may have just figured out part of my problem - this drawing shows the axle entering from the left side - when we took it apart the axle was coming in from the right side and that is how we have been trying to re-install it........left enter axle will hold that spacer and prevent the wheel from torquing on the brake hub/frame attachment point.......i suppose who ever took the wheel off to put the last tire on it before i got the bike put the axle in from the wrong side.

Routy's point about the repaired side being the "slack" or unstressed side during braking, would seem to go along with this repair nicely.  Looks a little cobby, but if the penetration is good, it ought to hold.

Title: Re: Rear Tire Change - not so freakin simple!
Post by weracerc on 08/16/11 at 10:16:33

i'll take cobby - as long as it is stout too - it is not in a very visible location - i am going to take the wire wheel to it and clean it up a tad before re-installing it.......with the axle going left to right.

Title: Re: Rear Tire Change - not so freakin simple!
Post by Routy on 08/16/11 at 10:51:00

Just for information,.....the axle nut is on the left side of mine, which I assumed was original, but being used w/ 3K miles, it maybe isn't.
But it seemed to work ok that way.

I at first would think it had to be a weak spot in the casting to break like that, but now I see that if the wheel was way back so that just a small part of the frame was in the casting, and then the wheel suddenly dropped, it would then have lotsa leverage to spread that casting apart. Bummer at best !

Post by scottnj on 08/16/11 at 13:32:44

Routy,  I just pulled my rear wheel a few weeks ago for a tire change and the axle nut was on the left side of mine as well.  I have an 07 too.  When I looked at the Clymer manual, I noticed the diagram showed the opposite, but I put it back together the way it was before I took it apart and have been running it that way w/o problems.

The part that broke shouldnt be in the wheel during tire change,,

I thot I had the Big Ooops award for putting a tire on,, I let a tire spoon get away & it hit me end on in the forehead when it came out of the rim,, & yes, it made a weird sound & I did some bleeding, while I laffed..

My rear axle also goes in from the right, nut on the left. The worst part putting it back together for me was getting that left side spacer to fit in there and line up with the hole. A second person helping does make it easier, as long as he holds his temper in check.

I feel your pain, man. One thing getting old and stiff and crippled up has helped me with is patience. Plus I always liked to work alone, even when surrounded by other people. Because of that, I have learned to do things that require three hands. I just aquired a 1976 XL 75 Honda as a project bike. 75. NOT 750. Now you you can feel my pain and test my patience against yours.  ;D

Too bad I didn't read this earlier. I have an entire rear brake assembly including shoes just sitting here. If your ebay purchase doesn't pan out, let me know. You can have it for the price of shipping.

the welded brake drum held up fine on the install and initial ride - 4 hands got r done - axle left to right......."on the road again, cant wait get on the road again!"

Heh heh.  I bet weracerc is going to wait until the next tire change to swap out the hub.

Title: Re: Rear Tire Change - not so freakin simple!
Post by weracerc on 08/17/11 at 09:39:57

you would be correct - hopefully 6-8K miles.......maybe even get to 20K total now 11,050 miles.........................even though i got r done i dont want to get r done again anytime soon.

I think the reason the repair is working so well is because you changed the title of this thread from "Why" to "Rear Tire Change - not so freakin simple!"

tee hee

I'd bet on that too !

But I'm not sure I would have welded it back on in the first place. I mean,....how often do you need the rear brake in reverse ?? :o


Title: Re: Rear Tire Change - not so freakin simple!
Post by Boule’tard on 08/18/11 at 07:34:16

I don't think it is there for reverse braking as much as holding the hub in one place.  If the brake was applied while rolling backward (not unheard of when scooting a bike around or on a hill)  then the hub could rotate out of position, then when the brake was applied in the forward situation again, the unbroken tab would get slammed and possibly broken.

Aw man,...!! Not an XL75,....! I bought a brand new one,...carried it everywhere on the back of my MH,.....wish I still had it ! I got in more trouble on that bike than any other one I ever had. It seemed that everywhere I went, I would run into Ranger Rick.....tellin me I wasn't allowed to be there ! A really neat lil bike it was !

I think I will get mine installed professionally.  I've experienced enough F*$@! moments when I was bobbing my S40.  I am pretty happy with it now, and don't need drama.

Local shop does the change and I can even get the tires shipped directly from internet shop.

I think about $75 for both tires...

Possibly not a bad decision, depending on your key word here,...."professionally"
If you had said "shop", I would have been tempted to tell some stories about the inexperienced kids that some shops hire to work
on my stuff >:(

Yep, I knew that,.....maybe you missed the hose clamp part ;)
