Drum brake casing grinds on rim XJ550 1982

Hi all,

I just had my wheels removed and taken to a shop for new tyres, and now that I got them back and fitted everything the rear wheel is a struggle to turn by hand.
My issue sounds like the one here: https://www.xjbikes.com/forums/threads/rear-wheel-not-turning-properly-after-removal.126676/
But it does not seem that a solution was found, and I have a chain drive.

Releasing the brake rod completeley does not help either, and I did not change anything to the brakes.

It feels like the casing of the drum brake is gridning on the rim side..
Is there anything else than the axle making sure these two parts are lined up?



Any input is appreciated!

 

do you have both spacers (collars) on the axle? parts 34 and 42
did the spacer inbetween the bearings fall down? part 2

I also looked at the drawings and wondered about the one in between the bearings. But looking at it now I don't think it is possible to miss it, and mounted everything again carefully but still the same issue.
Spacers 34 and 42 are in place.

Could my bearings or one of them be to thin?
I'm going to check the bearings and see if they are correct..

 

Is the chain too tight?

Not sure quite what you mean by this..

Can you hear a grinding sound as you turn the wheel?

 

Chains is good.

I was thinking first that the wheel was lined up completely wrong but I don't see that it is..

Sort of a grinding noise yes.
From what I gather the casing should only be in contact in the center. But it seems to come in contact around the edges as well.

 

It may just be the picture but that bearing looks a little off to me. Stick your finger in the center hole from the brake side and see if it spins smoothly. Can you get us a pic of the other side?

Try this, with the wheel off the bike put the brake plate in place and put the axle through the center. While holding the wheel with one hand, try spinning the brake plate with your other hand while putting pressure on the plate towards the wheel. It should spin smoothly with no grinding or dragging. If it does, then the wheel etc. is good and something is happening with reassembly to the bike. If not, the shop may have messed a bearing up.

 

Might be able to get a picture tomorrow of the other side.

I did try that before actually, and it is not smooth. It comes in contact even then, without tightening anything up.

I have not used the bike much, since I got my license just before winter, but the little I have used it it has been a struggle sometimes to move in and out of the garage, but my inexperience just thought it was supposed to be like that, Old and heavy bike, and did not register this noice. Could have become worse after it was disassembled or the shop could have made it worse putting on the tyre.

Wondering if either the wheel or something else could have been bent while any of the previous owners fell over with it, there are some scratch marks here and there. Making either of these parts a bit skew and therefore not making it a perfect fit anymore.

I was only able to read the bearing numbers on the other side, and that seems ok when googling.

Really appreciate the help!

 

The bearing on the brake side does not rotate smoothly, a major difference compared to the chain side.. so I think I need to change that, even though it might not be the issue but hopefully it is.
Should I change all three when doing one?

Got the picture of the other side:

 

Order the All Balls kit which will have all three with new seals.

this is important and you should be able to see this in place with the axle removed.

 

I will see what kit I get get hold of here in Sweden or somewhere else in the EU.

I can see the spacer in between the bearings, and I can move it around a lot, but not get it out of position so that the axle would miss it.

I might disassemble everything before ordering in case something else is missing or broken.

 

Hi all

I got all the bearings out today and the flange spacer was missing. I don't know if that would cause my issue, is it's only job to hold the spacing in place to be able to put the axle thru?

Will be ordering new bearings and the flange spacer now, hopefully I will get it fitted soon.

 

Flange spacer is for keeping it above axle hole to fit axle.

 

You should be OK - Sweden makes some of the world's best bearings (SKF)..!

 

Yes we do! I actually worked there for a little while a number of years ago.

But now I'll be ordering from the UK, because then I can get the seal, bearings and flange spacer from the same place.

 

Which place? Yambits ??

 

Yes! I have ordered from them before and also been in contact with them and it worked out great then! Feels better than a number of different eBay sellers and cheaper than ordereing it in Sweden from what I could find out. But it was tricky now because of covid-19, they only accepted a fixed number of order per day so you had to be there on time and a little bit lucky.

Hopefully I can still order from them after brexit.

 

Don't sweat over Brexit.. I doubt very much will change in terms of trade. Th UK buys too many German cars!

 

Hey, did you ever come across this guy too .?

https://www.spinnin-wheel.se/yamaha/

he sells parts and makes some entertaining youtube videos

 

I hade not!
Seems like an excellent place for spare parts!

I got my package with new parts yesterday, hopefully I can assemble it soon and everything is OK.

 

I would think the brake shoes are dragging a bit? Readjust them so they are in the correct position, ink them up with a Sharpie marker (or Svenska equivalent) for a 'witness' mark, insert the axle, then spin the wheel while holding the backing plate.
Take the brake backing plate off again and look at the inked shoes. I'm guessing the shoes got moved during the process?

It is hard to stay focused and actually notice things sometimes. I stand corrected, part 34 is missing! And I did not realise it before, by just looking at it assembled.
I noticed when I reassembled according to this guide https://www.xjbikes.com/forums/threads/rear-wheel-bearing-replacement-how-to-w-pics.35134/ that the inner-collar(part 16) hade been turned the other way around!?! It was sticking out on the left side which made med thick that it was part 34... A creative solution for not having all the parts I guess. But just to make sure I included photos of my assembly of the bearing and inner collar in the sprocket/hub side to make sure I did it correct?

I might contact this guy sooner than I thought....

Once I get everything correctly assembled, with all the correct parts, I will consider this if my problems are still there...

 

thats where it goes

 

Hi all!

The slowest mechanic in the world is back...
I just wanted to let you know that everything worked out fine and I want to thank everyone for their help.

That's the guy that solved the missing part, since it was not available from Yamaha anymore. Thanks again a100man for the tip!

So all in all a PO had lost two parts and flipped one the wrong way around. Not good.

Now I just need to find some proper gear so I can commute to work!

 

Cool. I came across him searching for a KL250 video after my brother bought one of those and was having issues. I like his approached and watched more stuff. Did you meet him?

 

Nope, did not meet him, just emails.
I explained which part and he sent a picture of for confirmation and I had it in the mail two days later! Really fast!

They are located a little to far away for going there for this. But could be fun to visit if I'm ever close.
