wheel run with no thrust washer

[pancho]

Well, here is the wheel that was run with no thrust washer, and the flange was directly on the wheel. What is going on here??? It there a steel cover over the alloy of the wheel? A steel core to hold the bearings? THe surface alloy damaged from heat and separating????  OK, pull the bearings, mill the surface, run with two or three thrust washers to get the proper clearance.....   Maybe I'll just break down and get another wheel for now. Anyone run into this before?

That is the worn out shoulder I was talking about in your first post.  I believe that wheel is toast, unless you want to weld and machine it.  Do a search on thrust washer, there are some posts that show similar damage and an undamaged wheel.

Here is a good shoulder on a rear wheel



I can't find the pic's from the other post of the bad wheel.  But that damage is definitely the result of no thrust washer.  

(I stole fordmano's photo from his post)

Here's the picture I was looking for and a link to the post

Good Luck!

In those bottom pics you can also see where the flange wore into the damper retaining plate. Unless you know of a good shop to fix that worn down area, I'd plan on springing for a new wheel. Probably the cost would be about the same.

[pancho]

OK, I see that the wheel material should be at the height of the bearing outer race.....  still looks like an easy if not time consuming job to fix.... mill the surface flat, make a bronze spacer on the lathe counter sink some screws.... aw that is for another day.. hubcapnc pointed me towards a wheel on eBay from pinwall,, I am trying to get them to look at that surface before I buy. It still looks strange to me how the alloy failed,,, looks like two dissimilar materials, I guess that is the result of heat and friction welding..

[Ricky-D]

I hope it works out for you.

That wheel is not beyond being able to be used.

The loss of material from the wheel reveals only a small amount of bearing race being unsupported and with the wheel all bolted up nice and tight with the axle there should be no problem.

The only thing needing to certainly be fixed is the space now enlarged by the erosion, which in my opinion can be taken up by a spacer and then the thrust washer.

Only when I ran without a thrust washer.    Hoser

There are steel cores cast into the wheel. A bearing mounted just in aluminum would be very prone to failure. If you had a bearing go bad, it would spin in the aluminum and destroy the wheel.

[Russell Rice]

Had that happen to me too. I just made a spacer and along with the thrust washer put it all back togather. I also replaced the flange bolts. I used tefflon for a spacer washer. If the thrust washer is made of plastic I figured tefflon would work just as well. I have about 10.000 miles on this set up and no problems.

OK,, now it all makes sense,,,, learning curve,,,, first bike I've ever owned that didn't have spoked wheels with steel hubs,, I'll catch on. I still have to agree with Rickey-D on this one... I think there are a number of options to make a solid repair on this wheel. I will try something, probably along the lines of milling the surface flat to the steel core and securing a bronze spacer,,, maybe for a spare wheel with a car tire. FOr right now, my thoughts are going along the lines of another wheel... still thinking.

[Ricky-D]

If you plan on milling to reach a steel core you are going to end up milling completely through to the mill bed.

There's no steel in the Valkyrie wheel, it's all cast aluminum.

If you look at the pictures Rickey-D, I think that is the steel core I am peeling the aluminum alloy off.....  check out what Grumpy had to say.. I agree that the bearing is still seated firmly, .. I am thinking along the lines of a bronze spacer,, just not sure of the best way to secure it yet,,, kind of thin for countersunk screws....  any ideas??

I would think the new spacer would stay in place just fine once the hub was pushed back on. JB weld to fill in the rounded edge maybe? I don't think I would drill anything into that bearing support.

[whitestroke]

Just make spacer i.d. snug on bearing race. at the same height of bearing race, add thrust washer and your good to go.
Could swear i've seen this posted with pictures within the last year.  Check out photos at end of post.

Good information whitestroke,, that post had a lot of detail on the problem, thanks. FOr some reason, my wheel only has .090 wear and it is already to the steel core, so I don't think building up aluminum is an option for me,, I will use another solution for THIS wheel. I did get my wing drive, and a flange is on the way from hubcapnc, so I will do all the rear drive stuff at some time in the near future. I will probably save it till last.

Pancho here is a good source for thrush washers, just figure out the thickness and dia.

Some thing else I would suggest, for the wheel to have that much damage there was a lot of movement, I would suggest replacing the damper bushings as there was apparently a lot of movement going on.

Oh yeah Grumpy,, the dampers are on my Partszilla list,, along with seals and a few other odds and ends,, just waiting, trying to come up with everything I will need for the bike and only do one parts order.....       


    yeah,,,,     right....
