Stephen Bridgehouse Posted June 11, 2019 Share Posted June 11, 2019 Hi I have a tdm 900 (2005) , done 40k and looked after. It's recently developed a noise from the front sprocket, a rattle and grinding noise on overrun. I adjusted the chain which seemed to improve it slightly. I'm sure it could be a bearing on the output shaft. Any ideas or anyone suffered a similar fault? Link to comment Share on other sites More sharing options...

Bearing is more of a rumble. Not rattle and grind that sounds more chain. 1 Link to comment Share on other sites More sharing options...
Moderator drewpy Posted June 13, 2019 Moderator Share Posted June 13, 2019 the chain should have a lot of slack, 50 to 60mm don't overtighten or the output gearbox shaft bearing will go. I'd get a new chain and sprockets if they are old, sometimes a hooked front sprocket will be noisy 1 Link to comment Share on other sites More sharing options...
Stephen Bridgehouse Posted June 13, 2019 Author Share Posted June 13, 2019 Hi, I've looked at the front sprocket and it looks worn. I'm going to replace the lot. There's a pickup sensor and castellated nut I'll have to remove to get at the sprocket, is this a simple remove and what is this nut torqued to when I put everything back together? Also, what is the torque setting for the sprocket nut? Link to comment Share on other sites More sharing options...

bikequeen Posted August 13, 2019 Share Posted August 13, 2019 if your chains are worn or haven't been changed in a while I would say it's best to swap both your chain and sprocket for new high quality ones https://autoready.co.uk/collections/drive-kits/products/yamaha-tdm900-2002-2013-steel-did-gold-drive-kit Link to comment Share on other sites More sharing options...
