The front roller has had the end caps replaced and I also had to make a new shaft because the old one was too worn where the bushes had given out. The only problem is the roller is too tight to move freely. I assume the shaft is supposed to be locked in position when bolted to the frame. Allowing the end caps to support the roller and also rotate around the shaft on the centre hub which acts as a bush. If so the the clearance between the shaft and internal bore of the end cap must be too tight. [Linked Image]
