cush drive?

[timwilky]

Not on mine, the Bros mille. done 5000 miles, but the sprocket can move a couple of mill within the wheel, clunking.

To me this is indicative a goosed cush drive. What is the org opinion.

I have told him to ask on a prillia forum

[punyXpress]

Ask Gr33K - it may be the same as a Falco

Check to see if the rear axle is done up to the specified torque and as you know check the cush drive rubbers.

you'll get abit of play but it shouldnt be much, 5000 miles dont seem much.

Your right Dave. Its the same setup as mine.

That does sound a little odd! My rubbers were very solid when I stripped my wheel to change the sprocket. And 5K miles... WTF! Can you move it with your hand? Got pic? Do you mean in and out movement or back and forward? if its in and out then thats what danger dave said. The drive is only held in with the wheel axel and bolt.

Cheers.

Oh and best Prilia forum imo http://www.apriliaforum.com/forums/

Cheers,

Nick

The movement is radial.

He is a mechanical numpty. I hate to admit he is my brother in that respect.

He had to be recovered at the weekend off the motorway with a flat rear. He said he could not find any puncture, took the wheel off and dumped it in water looking for air leaks. Non found so he put the wheel on, rode up to my house for me to torque up.


He told me to use 95Nm. Which I personally think to be a tad on the low side.

I might just nip down to his place at the weekend and pull the wheel off to check if he has installed it correctly.

I thin that would be a good idea. I honestly cant think of anything that could cause that from my inspection. Unless he has taken something out :S



As you can see its fairly fool proof design.

Good luck with the issue!

radial movement is usually just a worn cush drive, but i dont think it should be worn after 5k! but i guess it depends on the state of the rest of the drive train, loose chain etc.

I take it part 6 above are rubber bushes that sit over the sprocket pillar bolt heads and into the cush rubbers. The sort of movement he is experiencing would be indicative of these either failing or missing.

When I tried to explain the sprocket/carrier would simply lift out of the wheel he expressed surprise. I therefore assume he had not even tried to remove it whilst the wheel was off. Like I said he is a mechanical numpty.

LOL.

Yes you are right and its a real git to pull it out... hence he wouldnt know unless he tried. Well unless the rubbers are missing or damaged. But then it would probably just fall out. I hope he isnt meaning movement asin from chain stretch I.E. the wheel moves without moving engine. From what you say you cant be sure.


Please share the findings. Will be interesting to know what you find!


Out of interest what model is it? (year etc).
