rear wheel - cush drive rubber trick

Hi guys

I've mounted yesterday the rubber-mod for the backwheel on my 660Z - does you already know that (then i didn't catch it...)?
Now the rubber should hold longer than 15-20'000 km and there's no space between the rubber and the chain support.

First i cleaned the inner part of the chain support:

Then i produced eight pieces with 0.8 and 0.5 mm thick sheet (2.2 x 4.2 cm) and spice it together:

then i mounted them on the cleaned spaces

Now inserted the brandnew rubbers and there won't be any space left for a much longer time than without this mod.

If Kev or one of you UK-guys did already described this mod - sorry - otherwise - i just can recommend it.

cheers, Andy

I did exactly the same on my Tenere and the cush rubber drive lasted over 40 k km.
So thats a good improvement compared to stock. And easy and cheap too... :-)

Material thickness

Did you use those two different material thicknesses on purpose? Was it necessary to get the right fit for example?

thanks and sheet thickness

@snakeboy: nice to hear that your 'gums' lasted 40k km- my colleague has reached 30k and it still fits:).
@pepsi: thanks! the simple things are mostly useful.
@mb4807: the optimal thickness would be 1.2mm - i wasn't getting a sheet with this dimesion in my local shop, so i made my 1.3 mm sheet and pressed them together with glue to get it. one piece of 1.2 mm would be perfect.

I have just done this job using 1.5mm plate. With a bit of lube, the sprocket carrier slotted in to the new cush drives with no real problem. I did use a strap round the sprocket and to the spokes just to pull the assembly together to make refitting the wheel in the bike a bit easier. Just saying, you don't need to stress it if you can only find 1.5mm plate as was the case for me.

Cool - thanks for feedback and enjoy the mod. And the tip with the strap is very good - have it also done after a frustrating half an hour....it's so tight against the old 600-T�n's.

Just out of interest have you permanently glued these pieces into place?

@steve: yes they are permanently "glued".......

Cheers thanks deandy for quick reply I am going to have a go at that one.

Hiya deandy got the metal sheet going to be a winter project. Just one question why the corner cut off.

It's just clearance to allow for the shape of the casting. It widens towards the wheel centre so you can't just use a rectangle of metal. You'll see when you crack open the cush drives. It's very obvious.

what glue did you use?

Rear-wheel gum-mod

Hi guys

I'm still enjoying the direct drive with this mod:sbike: for several thousands of kilometers this year.

@Ranger6: The inner part of the sprocket is going "up" - you'll see it when you unmount it - you can see it on my images if you know where to look. It was necessary to get the sheet fully on the spocket. Doesn't cause any damages or missing anything - the rubber isn't coming out to the edges of his space. correct as mb4807 already wrote.

@tenyammann: Simple '2-component-in-minutes-dry-glue' - if it's not fix after some years - i'll glue it in again at the next tire- or rubberchange.

Happy und safe rides!

cheers, Andy

Hi bow

As written in my last comment:
Simple '2-component-in-minutes-dry-glue' - if it's not fix after some years - i'll glue it in again at the next tire- or rubberchange.

It's anyway pressed in with the rubber - there can't be happen any damages - if you check it at the change of your rubbers.

Great mod Andy and well explained. :applause:

I've taken the liberty of amending the thread title (by adding "cush" and "drive") to make it a bit easier for folk to search/find it in future.

Thanks Pleiades - and also thanks for your pcv-map for the z - will load it up when the commander arrives. Have the same setting except double Akra's instead of yours.

Perfect thanks - would be a shame if someone isn't finding it.

cheers, Andy
