The usual problem with that big casing is the awfull machining. It pays to spend a little time with some emery paper to improve it where it bears on the seal.

I have never under stood or worked out how the U type spring tensioner under the slipper adjustment is meant to be efficient it really only stops the slipper from bouncing when the chain is in the slack position and no weight on it I found a suitable size coil spring and put it on the buffer bolt on top of the rubber buffer to the under side of the tensioner with suitable washers for extra contact area this then pushes the chain up onto the chain when slack to stop some flapping about and when the chain is in its tight spot allows the spring to compress .It acts like a rear chain tensioner. Don't have a too strong a spring so that it cannot compress when the chain is at its tightest I have also left the U spring in place. Has any one else thought the U spring was not very good ?
