atom3624 Posted April 3, 2015 Share Posted April 3, 2015 Is the motor loose? If the motor pinion doesn't mesh with the gearbox spur, the gearbox cannot move (unless that's been unscrewed, which is unusual), it's more likely that the motor screws have loosened and thus doesn't mesh. Get a couple of photos up. Al. Quote Link to comment Share on other sites More sharing options...

Andythecrane Posted April 3, 2015 Share Posted April 3, 2015 Via photo bucket. There is a guide on the forum somewhere. Sent from my Nexus 5 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
Rattymatty Posted April 3, 2015 Author Share Posted April 3, 2015 To adjust the gears then I got to loosen the motor and slid it to mesh the gears?i think it might be a worn spur then because the motor is all the way over. Quote Link to comment Share on other sites More sharing options...
Cammie838 Posted April 3, 2015 Share Posted April 3, 2015 The spur is a cog that sits on the clutchbell and that in turn, turns the gearbox and your wheels. if the clutchbell doesn't spin I'd guess your clutch is gone. If the spur is worn it wont have any teeth. Quote Link to comment Share on other sites More sharing options...
Rattymatty Posted April 3, 2015 Author Share Posted April 3, 2015 Yeah the plastic gear on the gearbox side does have worn teeth,the metal gear on the engine is spinning when the engine is running. Quote Link to comment Share on other sites More sharing options...
Cammie838 Posted April 4, 2015 Share Posted April 4, 2015 Just a worn spur gear then mate, simple cheap fix. Just make sure you line the engine up straight without any tight spots when you spin the spur gear over when setting the mesh and you're good to go. 1 Quote Link to comment Share on other sites More sharing options...
