Fitted these Yoshi blocks the other day..bearing in mind Ive had the back wheel off this bike dozens of times for new chain..servicing...tyres etc.. so it was a simple remove and slide axle pin out swap over rhs oe block for yoshi block slip in the spacer...fit sprocket and spacer ..lined caliper up... slipped pin back in fitted lhs yoshi block and washer check over...all good, spinning freely...adjust chain..torque to 100nm.... was going to go for a blast tonight heard noises from rear end as I wheeled her out and decided to inspect... took a few mins to see this...wtf ! Initially I cracked the axle nut and the wheel span beautifully...nipped it up again and found it quite tight... what the hell has happened ... any ideas.. my rear wheel is badly chewed where the rhs spacer sits in...can only think it's the adjuster blocks.. any ideas lads ?

Is your torque wrench ok? Surely thats been overtightened? Whats the thread on the axle like? Is there any damage or wear on it?

Na everything is all good just the spacer and rim lip... that wrench is maybe 18 months old..always zeroed after use, so doubt it's that Soof..I'm really stuck for answers on this one.. I have a new spacer, but it sits really tight against that edge now... jesus !.. I've checked a blow up of the rear assembly, I done it right, watched a vid, exactly as I put it together.. I've done it so many times before with no problems...

Anyone else have this problem ?

hows the spacer from the l/h side. that r/h one should push against the wheel center tube. i doubt its anything to do with the yoshi blocks as there on the outside of the swing arm

Heres some other images

Is this the first time you have used the bike since you got it back from the dealer?

So I carefully levelled off the jagged pieces from the rim with my Dremel..not ideal but I had to do that so that I had a base to start from.. I placed both NEW spacers where they should be, removed the Yoshi blocks and replaced everything as it should.. ensuring the rear caliper slid on the carrier and the body slid freely on the guide pin..all good, had Neil my mate go over it with me just to cast an eye incase I had missed something, we double checked the lot.. spun the nut up hand tight and the rear wheel was spinning lovely... got my wrench out and started to load up the rear axle and the wheel started to seize up again..at this point I was nowhere near 100 nm..... continuing on the wheel is almost locked solid, it's almost as if something within the wheel bearing/shaft assembly is compressing beyond tolerance and the whole thing is seizing up... it must be something I am doing..has to be, or possibly something has given way bearing/spacer wise inside the hub.

Thoughts ?

Bad luck stuart. Are the Yoshi blocks exactly same thickness as the oem ones? If slightly thicker perhaps when torqued up it is overtightened.

No I was out all weekend Soof sure..500 miles or thereabouts.. funnily I heard this strange clunk a few times when I pulled up Monday night outside the house..it was from the back end... it wasn't that loud, but now that I think about it !.. Neil was with me and we were chatting as I slid the bike into the garage... pulling it out tonight I heard it again as I pushed her onto the driveway...hence where we are now...arghhhhhh

Not them FS, we reinstalled the originals...same thing now, it's actually even worse... I wonder if one of the bearings is starting to fall apart.. but looking in the hub theres nought visible...bearings seem to be rotating freely...

Also I had suspected I had fitted the blocks incorrectly...but I read that you can rotate them 180 degrees...so I knew instantly it wasn't that.. **** knows what it is... I'm going to look at an exploded view of the rear hub assembly and components to see if a spacer or shim is amiss.. saying that the back end on these things is pretty straightforward...

We need pictures of how it was installed.

Both sides and from underneath where the spacers are.

Another thought. Could you have mixed up the spacers. I think on some wheels spacers are different width by about 5mm.

No they only fit one way... and are not interchangeable

I'd need to go back out to the garage and disassemble it Alex... I'll do it tomorrow, but you now it only one in one way...doing my head in now...I'll call dalkeith in the morning

Do you use the original axle nut? Maybe the mechanical lock has failed so its overtorquing? Anyone who can let you try another oe nut nearby?

Same nut it came with..totally stock.. I have a stainless steel nut I could try...surely it can't be the nut, it was starting to bind when not even half tightened when we reassembled evrything back to standard.. I think possibly something has given way in the hub...

Try the other nut and see what happens.

I'll look at it tomorrow Soof... sitting here in my gym gear fucked off well and truly, need to get a shower and cry

I think it may be inside the hub !.. what else can it be ?
