welsh Posted May 5, 2008 Author Share Posted May 5, 2008 (edited) Have you tightend the slipper clutch up and did you check the diff?? yip i tightened the slipper clutch up so that when you hold the right wheel and the spur gear the left wheel will turn but its stiff (as it says here http://www.racernine.com/X-CellElec3.html ). also tightened up the diff via the hex key you can alter when you pop off the axles etc. Edited May 5, 2008 by welsh Quote Link to comment Share on other sites More sharing options...
tonycat Posted May 5, 2008 Share Posted May 5, 2008 Try holding the car give it some revs and see if the spur spins to me it looked like on the pic that the clutch pad was worn out by the mess on the car.. Quote Link to comment Share on other sites More sharing options...
snowbl!nd Posted May 5, 2008 Share Posted May 5, 2008 Just watched the video - something certainly isn't right. It shouldn't need to rev that high to get moving, that's probably a clutch problem. If you've checked the slipper clutch is tight then take a close look at the clutch housed in the bell. when i manually turn the spur gear the right wheel turns fine, however the left wheel turns but not as much. so if i turn the spur 5 times for example the left wheel will do a complete turn but the right will only move a quarter turn for example ? is this a diff problem? the manual says it may need altering after run in ? This can be can be caused my a number of things - damaged gears in the diff, gritty bearings, more resistance on one side (material wrapped around an axle etc), rounded hex on one side. Rebuilding it would probably be the best bet. Quote Link to comment Share on other sites More sharing options...

You said you tightened the slipper, but did you take it apart to see if the slipper pad was worn? If it is worn it would need replacing and could be causing your problem. Just read on the XTM website that the X-celerator has a ball diff. It could be that the balls in the diff are a bit worn, or the diff gear that the balls sit in is worn/has teeth missing. These could both be leading to your problem. I would get the diff out and strip it down, replacing any worn parts, post some pics if you need help. Do the same with the slipper clutch. Rebuild it all and try again. Be careful not to over tighten the slipper clutch, this can lead to problems with your diff. With the car held still you should be able to move the spur gear by hand when applying firm pressure. Edited May 6, 2008 by RCChris Quote Link to comment Share on other sites More sharing options...

welsh Posted May 17, 2008 Author Share Posted May 17, 2008 hello again, it seems that the reason the car would not go is because the flywheel is slipping on the collet and there are brass shavings all over the car. So i replaced both the flywheel and the collet but after 2 tanks of fuel there is lots of brass filings all over the car again and it wont move. It seems to be stripping the collets, is there anything that can be done to stop this happening? The hex which tightens the clutch bell and everything together is done up super tight.... ??? thanks Quote Link to comment Share on other sites More sharing options...
