400/4 Wheel bearing questions ?

[McCabe-Thiele (Ted)]

Just a brief update on the rear wheel bearings - I followed the tip by K2-K6 & fitted the rear wheel, spacers etc and tightened up the axle to check everything was as it should be. Wheel rotates as it should - I will remove it again to check the lock ring, fit the new drive cushions & rear sprocket over the next few days weather permitting.

Progress is going well despite an avoidable  setback on Wednesday when I was pushing my ramp out of the garage to turn the bike round - I pulled on the front wheel - the bike came of the centre stand in slow motion landing on the closed centre stand. . I had some old carpet on the bike ramp plus some blocks of wood so luckly no damage caused but it could have been nasty.

Bike was far to heavy to lift it back onto the stand myself so on Saturday my Nephew & his mate lifted the back end up as I put the stand down & Wendy pulled the carpet out!

I will ensure the rear wheel is not absent without adequate safety blocks in place - yesterday I cut some nice chunks of 4" x 3" to the right size - my car axle stands are too big to be of much use.

Is the front wheel not held in a clamp on your ramp Ted? Having said which, I will put my hand up to performing something similar in my youth,  bike on centre stand (on tarmac surface), mate leaning on rear carrier so I could remove front wheel, wheel out and let bike gently pivot forwards to rest on fork legs. NAH!!!  Rolls off stand and hits the deck.  Fortunately only cosmetic damage.  Nowadays always keep a good stock of wooden blocks and ratchet straps. Stay safe.Mike.

Hi Ted. I'm looking at my rear wheel at the moment and noticed a fair bit of play between the sprocket and the hub. I attach a photo as it makes it clear where the play is coming from. Looks like wear on the washer and large circlip. Wondered if yours might be similar. Do people shim these washers?

Are your drive cushions in good condition - as you know these are what the rear sprocket bolts into - also is the drive sprocket an oem part?

Yes but clamp should have been tighter - me pulling on the wheel instead of the clamp unit  was the primary cause. The straps I have used were starting to get out of position as I worked on the bike.

I still haven't found a Torque Setting for the lock rings only for the axle nut.

(my) Manual(s) only states [use thread lock cement when installing the bearing retainer], no torque setting though...

Put a ratchet strap on the centre stand with the other end on the lower fork triple crown, tighten reasonably and the stand will never fold up.

Put some washers behind the sprocket so it sits further out?

Would it not be better to fit a thicker washer behind the circlip so it does not affect the fit of the bolt lugs in the drive rubbers?

[smoothoperator]

Yes, I think fitting washers would work, it didn't occur to me to do it that way. AFAIK the sprocket is original or at least a genuine replacement, Bike has 38,000 miles recorded.

[McCabe-Thiele (Ted)]

If you could find a washer that big Ted.

Shouldn't affect the positioning or fitting or the lugs into the rubbers, fit the washers between the sprocket and the lug, that won't affect anything except to move the sprocket a little further out.

Could this movement be deliberate to ensure the drive spr
ockets are in line when the chain is fitted or am I thinking engineering nonesense?

[McCabe-Thiele (Ted)]

What's yours like Ted, if yours and others are the same then it's mist likely deliberate but to me it shouldn't be there. Any movement of the sprocket will eventually wear parts that aren't supposed to be worn IMO.

My original rear wheel has some play like Steve's - I haven't fitted the drive rubbers yet on my new rims so not sure what they will be like yet.

I just had a "whats mine", moment so been to have a look. There's not a great deal of play in mine. Not enough to measure anyway. Ive got new cush's in mine though which os probably why.

[Laverdaroo]

Yes, sorry, wrong language. I was wobbling bits on the vfr while I was out there looking, yer know what’s it’s like!
While I’m here, I wonder??……..

I have a similar GAP but only a rizzla’s worth bit as said, o do have the new drive rubbers in

Finally  fitted my rear wheel this morning - new drive cushions & sprocket fitted -  the large washer (2mm thick approx:) circlip was a snug fit I had to push it hard down for it to snap into place - pleased to report no wobble/side movement.
