Kef construction Posted May 3, 2017 Share Posted May 3, 2017 Hi all,Got a problem with the truggy went to use it at weekend, and runs fine off the ground, Problem when I put it on the ground it won't move but everything turning as it should, also makes like a torque sort of sound Any help or advice will be much appreciated Thanks Sent from my D5803 using Tapatalk Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted May 3, 2017 Share Posted May 3, 2017 Check the grub screws on your driveline starting at the pinion Quote Link to comment Share on other sites More sharing options...
dazp1976 Posted May 3, 2017 Share Posted May 3, 2017 (edited) Usually in these cases it's the internal spider gears. Loses power through the non driving wheels and struggles to move. Can spin fine off the ground through momentum. A way to check is holding the other wheels while only one spins to feel how much force is there on the others. if not, Could be a grub on the input cups or an internal drivepin Edited May 3, 2017 by dazp1976 Quote Link to comment Share on other sites More sharing options...

dazp1976 Posted May 5, 2017 Share Posted May 5, 2017 (edited) Center diff spider gears. Open it up and have a look. Looks like it tried to drive at the rear but there was no front drive so all power lost in the diff where the bad gear just spins up. Replace with 101142 hard gears and oil. I use 30k. It would work fine with wheels off the ground through momentum Edited May 5, 2017 by dazp1976 1 Quote Link to comment Share on other sites More sharing options...

Kef construction Posted May 5, 2017 Author Share Posted May 5, 2017 Yeah it works off the ground, reverse seems to work fine as well, should this be happening after about 5 hours use? Sent from my D5803 using Tapatalk Quote Link to comment Share on other sites More sharing options...

Sent from my D5803 using Tapatalk If it turns out to be that and If it's still using the standard steel diff internals then you've done well to get 5 hours Since I put the hard ones in I haven't had to replace them for a year so far. 1 Quote Link to comment Share on other sites More sharing options...
babylon Posted May 5, 2017 Share Posted May 5, 2017 So, Would this not come under the 2 year Warranty, Or do they class it as a wear and tear part, Thus giving them fall orthority to keep using parts not fit for purpose. Quote Link to comment Share on other sites More sharing options...

I use a 0.2 & a 0.1. Quote Link to comment Share on other sites More sharing options...
