Trying to change the timing belt on my 2006 BRM Jetta, I ran into some difficulty. The new belt was very stiff. To get it on, I had to remove the camshaft sprocket, put the belt on the sprocket, and put the sprocket back on the hub.
Unfortunately, I think I didn't get the sprocket all the way back on the hub. When I attempted to tension the belt and torque the sprocket, the misaligned sprocket swaged a "lip" of metal on the bronze colored portion of the hub. Picture:
(Picture somewhat exaggerates the size of the "lip" due to perspective effects. It's about a millimeter high or bit less.)
After three fruitless attempts to get the belt + sprocket on straight, all of which resulted in the sprocket being out of "true" and the belt wandering off the sprocket in the direction of the cylinder head, and the last of which culminated in the sprocket requiring a couple of taps with a hammer to release it from the hub ... I tried to just press the sprocket on by hand, and discovered that it doesn't go on the hub anymore in any mode except "wobbly".
I need this car to be functional asap. What should I do ... (a) try to carefully file down the "lip" enough to get the sprocket to mount flat on the hub; (b) try to buy a new hub and get it airfreighted; (c) give up, put the motor mount back on, and have the car towed to a VW shop.
