Baja5B Posted February 27, 2012 Share Posted February 27, 2012 spur gear and pinion gears are fine, fitted a stronger 8000RPM clutch spring, after putting that on I was reving to half revs before the wheels starting spinning and travelling very slowly, could it be that the clutch spring is very tight and will it weaken over time and sort the problem out? is this the problem or is it somthing else? thanks Quote Link to comment Share on other sites More sharing options...
stebro Posted February 27, 2012 Share Posted February 27, 2012 (edited) Could be a dog bone pin, Busted gears, rounded wheel hex or broken clutch. Best way is have a quick look at what doesn't move when revved up. Or it could just be you not givibg it enough revs to get it moving Edited February 27, 2012 by stebro Quote Link to comment Share on other sites More sharing options...
norcoforever Posted February 27, 2012 Share Posted February 27, 2012 have you only revved it to half way as on a stock engine thats roughly when the 8000k clutch kicks in or is this at full throttle? Quote Link to comment Share on other sites More sharing options...

Or it could just be you not givibg it enough revs to get it moving the gears are all fine, wheels arent rounded or the hexes broken, must it be the clutch? so nothing to do with the new spring? and what is the dog bone pin and where is it :/ please? and no i gave it a good 5-10secs on full revs and it was only travelling very slowly have you only revved it to half way as on a stock engine thats roughly when the 8000k clutch kicks in or is this at full throttle? i tryed full throttle for a good 5-10 secs Quote Link to comment Share on other sites More sharing options...
stebro Posted February 27, 2012 Share Posted February 27, 2012 Dog bone pin it the pins that go through the dogbones ( driveshafts ) these can break. If it moving slowly i would say the clutch isn't engageing right, i.e it isn't opening up correctly to give full drive Quote Link to comment Share on other sites More sharing options...

stebro Posted February 27, 2012 Share Posted February 27, 2012 No really. Could be something stopping the clutch from opening. The clutch bolts may have not got a washer in the right place. I have a 9500 rpm spring so thats real tight but i have no problems moving Quote Link to comment Share on other sites More sharing options...

Try rcmodelz They stock most baja bits and are quick . clutch should be about £20/30 . shouldn't be a problem to change the shoes. Just get them the right way round(there is usually an arrow for direction) Quote Link to comment Share on other sites More sharing options...
