Hi Guys

I was a little too agressive while working on my panzer 4 today and broke off one of the return rollers. I glued it back on but now it doesnt spin at all? I ran the tank and the track passes through it fine so was wondering should I try to obtain another roller or just leave as is? I assume that its fine because the rollers dont really do anything except keep the track in line?

Thanks guys for any advice
Jeremy
