Hi any one noticed that the slipper appears to be out of whack, inside edge of chain barely makes it to pad material but outside has 8 to 10 mil clear of chain, you cant move it inboard as this is set by the pivot stud would have expected it to run central, maybe they bent the curve the wrong way in uk and the indians followed suit. Any thoughts on this.

They all do that Sir!

Doesn't make it right of course, just makes it cr@p.



One of my Enfields had the same problem where the innermost set of chain plates never sat on the tensioner at all.

When viewed by strobe light the tensioner could be seen to twist the duplex chain on its approach to the underside of the drive sprocket, not only making a horrible noise as the inside edge of the chain plates made contact with the outer edge of the drive sprocket teeth but also producing very fine metallic swarf at the same time.



Perhaps they've changed the design inside the case, but I removed metal just from the pivot section of the slipper plate (and mainly from the inner side) at an angle to reposition it much closer and parallel to the inner case.


Finally I opted to shorten the bush to sit inside the pivot curl not extend beyond it, removed the inner washer to better position the tensioner closer still to the inner wall and now underneath all of the chain width and then added another nut onto the end of the stud to locknut the slipper plate down into position after tensioning it, thus preventing the slipper plate rocking under tension from chain overrun.



End result was no more swarf, a lot less noise and no more regular chain adjustment.

This post makes me nervous but I`m not going to look.
