i have used silicon rubber tube thats used in rc cars or you could use rubber fuel and vaccum tubing you can get that at the auto parts store but i use the blue silicon one,, just remember that it needs to fit snugly on the capstan shaft i had to cut a few just to get it right the wheel will touch the tubing causing it to turn but if not cut the correct size if it too big it will not work if to small once it starts turning it will slide towards the bottom ,, now to put it in there you have to remove the capstan clean the shaft then put your piece of tubing in the little housing then push the capstan shaft in though , and since you have the deck apart you might as well replace the belts in the process,, if one of the guys here know the demensions of the little tube then you would not have to cut pieces like i did because mine did not have anything in there......
