RedRooster Posted June 6, 2011 Share Posted June 6, 2011 I've never done a Triumph one, but have rebuilt 3 (of different ratios) for the Sprite, its not that difficult to do once you get your head around it. If you fancy having a go yourself i could help with a few links.RR Link to comment Share on other sites More sharing options...
Clive Posted June 6, 2011 Share Posted June 6, 2011 Mike papworth has an enviable reputation. Probably available cheaper elsewhere, but riskier.trouble is, with a used crownwheel and pinion it is not always possible to build a silent diff. However, shouldn't be too loud if set up correctly. I know a local chap and he talked me through how to do it. Sounds easy when said quickly over a pint ;D Link to comment Share on other sites More sharing options...
John Bonnett Posted June 7, 2011 Share Posted June 7, 2011 They whine when the case hardening has worn through and no amount of setting up will solve that problem. Link to comment Share on other sites More sharing options...
