T3 Cast Wheel - cush drive not fitting

I have a cast wheel which has been powder coated (by a previous owner). On a previous thread I've described the problems I've had removing the drive plate. I'm now trying to reassemble the cush drive and drive plate. Placing the rubbers in the hub I would expect them to fit snuggly. In my case they need to be pushed in with some force. Once all the rubbers are in place the vanes on the drive plate will not fit between rubbers easily. Even with lots of force (standing on the drive plate) they will not slide in.
Surely this is not correct? What I think is happening is that the powder coating is too thick and squeezing the rubbers so that they are taking too much space and making that gap between then too small for the vanes in the drive plate.
Should I expect the drive plate to slot back onto the wheel with minimal force?
Looking forward to your advice!
Thanks in advance,
Miles
 
Trim the rubber pieces to get the clearance you need. Your reason for not fitting well is correct. Drive plate should be a slip fit, not loose and not tight. Considering the age of those rubber pieces, you may want to replace them as they get hard with age. They are part number 14336803 and you need 12 of them.
 
Cush drive rubbers expand with age.

Obtain a new set. I bet they fit because powder coating is just not that thick.
 
I've had a similar issue with my T5, though in my case the wheel still has the factory finish. I pulled the wheel out for a tyre change and some other work but when I came to refit the wheel after about two weeks there was no way I could get the drive plate to fit. I tried Morris's red rubber grease and lots of force, but still nothing. The rubbers were hardened and the drive plate separated easily on disassembly. My only thought is that they somehow expanded in my workshop. I got a new set of rubbers, but they all had a significant ridge around them that needed trimming before fitting (I took it off on my 80 grit bench sander). Everything then went together firmly with no play and no excessive force required.

Why remove the drive plate to change a tire? I've changed many tires and never removed the drive plate.
 
Agreed.

I said "I pulled the wheel out for a tyre change and some other work" The other work was that the circular splash shield was missing when I got the bike and when I came to replace it two of the three studs were snapped off, one having had a previous attempt to drill it out and the drill had run off to one side into the alloy.

Please forgive me. Didn't know what the other work was. Looks like you are in need of a time sert for that wayward drilling operation. Hope you have success with the repair.
