dr nosh Posted March 4, 2014 Report Share Posted March 4, 2014 Can anybody please explain how the chain plastic/rubber tubes fit at the front end. I can see how they fit over the rear wheel sprocket using the alloy T bracket, but at the front the top run just rests on the swinging arm, and the lower run just rests on the frame. Is there supposed to be some bracket ? I have not fitted the chain yet, but even with that fitted, it looks like they will just rest on the chain. Any clues?

29markt Posted March 4, 2014 Report Share Posted March 4, 2014 Have you a chain tensioner fitted? If anything like the 200 Cota set up, could that take the slack? Quote Link to comment Share on other sites More sharing options...
tayld Posted March 4, 2014 Report Share Posted March 4, 2014 Hi there, You are right about the front end of the chain tubes being supported on the chain when it is fitted. There is only the "T" shaped bracket. The "T" shaped bracket can wear out where it pivots on the rear wheel spacer. If you have a chain tensioner fitted with the pad just behind the gearbox sprocket the front end of the chain tube should be clear of the pad. Replacement tubes we have bought lately fit both top and bottom runs of the chain, the bottom tube has to be shortened if a chain tensioner is used. Saw the excess off with a junior hacksaw. 1 Quote Link to comment Share on other sites More sharing options...
dr nosh Posted March 7, 2014 Author Report Share Posted March 7, 2014 Thanks tayld. Confirms my thoughts. The T bracket is new, so will watch out for eventual wear. I do have a new chain tensioner but not fitted as yet. Going to do this at the weekend...I hope.....time permitting. Quote Link to comment Share on other sites More sharing options...
dr nosh Posted March 14, 2014 Author Report Share Posted March 14, 2014 Found the chain tensioner. Brand new, from a dealer....universal.Fitted......but way out of line with the chain. Main part of the spindle replaces bottom M10 engine bolt. Will need to remake this longer. The arm pivots on a M6 screw in the end of the main spindle. But the pressed in bush in the arm is i/d M10. How is that ever going to work reliability! Will make a bush to match an M6 stud for the arm to move on. Can be cleaned/lubricated regularly. Trying to do some more this weekend.
