Title: Unable to install rear wheel back on my M600 after removing it
Post by: V00rt on April 11, 2015, 04:14:40 AM
Hi guys,

It's the first time I'm posting here in this forum. I tried searching for problems similar to mine but haven't found any solution.

I am basically encountering difficulties when reinstalling the rear wheel of my Monster 600 for the first time after having a tyre change. It seems that i cannot fit the caliper holder plate when everything was put back together. It does not slot between the wheel and swingarm for as much as 1cm. I am noticing that the bearings do not fit flush with the rim, but they seem to seat in correctly.

I am posting a number of images to give you an idea of the problem. Can you please check them out and maybe point out to me any anomalies?

Any help would be greatly appreciated.

They do seem to be protruding. Were the bearings changed by you or the shop when the tyre was changed?

Bearings weren't changed, although I have now got a new set which will be fitted. The caliper holder plate should be able to slot in easily between the rim and swingarm without requiring any additional force right?

It should squeeze in with a wiggle. Have you given the bearings a tap to seat them (on the outer race)? Is the inner spacer tube rattling about?
There should be a slight protrusion so they don't bind, but it should fit when the wheel is in square. The LHS spacer is in the correct way (flat side out)? It was in the other picture.

Maybe the bearings are ok, maybe just a trick of the photo. The sprocket carrier in all the way?

In fact the sprocket carrier does not go all the way in when the bush is installed (picture 3), as it hits the bearing first before full contact can be made by the carrier. I will have a look at the bearings and replace them while I'm at it. Will report back with any progress or otherwise.

Thanks for your observations :)

Actually I see nothing wrong . . .

Get the chain on the sprocket, axle on one side, caliper side and let it actually rest on the axle(caliper carrier), wiggle the wheel while pushing axle thru, if you are alone, get a piece of wood of about 4cmx6cm and put it under the wheel . . .. you should be able tofit the wheel.

Just remember there is a pin to fit the caliper carrier so that it doesnt spin

Had a M600, for some reason bearings did loon like that; but I did tap them with a rubber mallet....

Thanks for the suggestions.

I have replaced the bearings but the problem still remains. The spacer tube between them fits snug without any rattling about meaning that there is direct contact. I don't know, maybe the swing arm is warped after all? I have also tried locating a YouTube video of someone replacing an M600 rear wheel but to no avail unfortunately.

Other things to check and consider.

Double check the location of the brake pads in the caliper.

Line up the axle adjusters square with the axle in the swingarm (no wheel) and check how it looks.

Check it with the wheel and axle installed, but no brake bracket and check how the wheel sits. This may let you see a problem with the swingarm if there is one or let you spot the component that is catching. Put the spacer part of the bracket in the gap. Does it look like it will fit?
Does the caliper bracket locating pin appear bent?

Did the wheel feel tight in the swingarm when you removed it, or did it drop out once the axle was removed?

Try what DM620 suggested and put the axle in from one side to help line up the components. It may be a technique issue because you are alone.

You may have to put the caliper on last off the bracket. You can try unbolting the caliper so you can just play with the bracket for fitting.

You will find the problem.

If the wheel came off easily, it will go back on easily.

I carefully looked at each photo and see nothing wrong.  Since the tire was mounted and the old bearings were reused, well, SpikeC is correct.  Except it doesn't fit [bang]  All I can think of is find another Monster with the 17 mm. axle and 4.5" wheel, get out your measuring tools and compare.

After a couple of hours wrestling with it, I managed to fit it right in with the help of my Dad :) It was a matter of technique as koko64 pointed out correctly. The wheel now spins freely when jacked up so there isn't any sign of any access strain on the swingarm/rim.

I thank you for all helping me out in such a timely manner! What a fantastic forum :)

those bearings, esp the rh, are too far out.  something is definitely wrong with it.

I will have to remove everything and asses the situation as the rear caliper did not mount correctly in line with the disk brake.

Can someone give me an indication of how the bearings are supposed to fit into the rim exactly? As i am not sure if they are supposed to be flush or slightly protruding outwards. An image would be greatly appreciated.

Close to flush.  Even though your photos are good, for me it is hard to tell.  In one photo the l?s bearing seems to protrude too much.  In Another it looks fine.  brad black says they protrude too far.  I have to concede to an expert.  Weird thing is if bearings were not changed what went wrong?

Check the pads havent both moved to one side of the disc. Also push the pads back and the pistons behind them to make room for the disc, then put the caliper on the bracket over the disc. Pump the brake once the caliper is bolted on to centre the pads on the disc.
I have never worked on an M600, so I dont know how far the bearings should protrude, but they do seem to sit out more than Ive seen on other models. Brad knows this model well and so does DM620, so I defer to those guys who are Ducati techs.

Here is the rear of my 695 blown up

I know there is a slight difference in the space shape

But I hope it helps a you a little

It looks to me that you have the spacers in the sprocket holder the wrong way around maybe?

I have shown mine in the way they should go if they are the same on yours?

The cone shaped spacer should have the larger diameter against the swing arm.

Yours is backwards Will.

Post by: V00rt on April 14, 2015, 03:57:08 AM
That's great Will thanks for the images!! They are exactly what i was looking for :)

And yes, as ducpainter correctly pointed out it seems that the cone spacer is fitted the wrong way round.

To the OP...

are you using OEM bearings or replacements from a bearing supply?

Is it possible the replacement bearings are wider than they should be?

Post by: Willthedub on April 14, 2015, 07:25:22 AM
 :o Oh thanks duc!

This will push my sprocket out a few mm then, I wonder how long it's been like that

I haven't got my engine to be able to line up the chain

thank you very much for the advice!

Any progress on yours V00rt?

is the spacer between the bearings in the wheel the right one?  they're being blocked from seating in the wheel by something if they are in as far as they will go.
