Durga help, Thanks
 

Hi everyone I am new to this forum and have recently purchased a Tamiya durga that has a Novak 7.5 GTB and run all orion 3200 lipos. I have also purchased a few upgrades: TRF 501x damper set, DB-01 slipper clutch, front and rear aluminum suspension mounts, and CVD's. Any way i have recently run into a problem with it, after every run the front diff loosens up really bad and sometimes doesn;t even last the whole race. The car is new to me and if someone could please help me out that would be great.
Thanks

Take the diff apart and give it a re-build.

When you put it back together make sure when you put the thrust bearing in, make sure it is well lubed up with something like Associated Black grease and that the screw head goes on the side with the indent in the copper coloured bit (you'll see what I mean). When you've built it, tighten it until it doesn't slip. Then run the car at 1/4 ish throttle holding one of the wheels for 20 sec or so, swap over and then hold the other wheel. Adjust the diff as required and keep doing this until it doesn't slacken off any more.

This advice was given to me by DCM on here and it works. I haven't had any trouble from mine since building them this way.

thats about it dude. But one advice, if it has been slipping badly, it may just be good to put some new balls, plates and diff screw/nut in there, get everything fresh. And pay attention to which side the screw goes in from, as there has been some confusion building the diff.

I knew I'd forget something :blush:

thats why I did airframes and engines, and you play with wiggly amps Mr Tomlinson!!! :woot:

Ceramic diff balls and tighten the screw/nut all the way then back off ~1/8 turn so the spring isnt bound up. Some thread locker is a plus as well. No diff problems here yet running as a speed car with a 3.5R.

no, never do that with a tamiya diff!!!! you will crack a diff plate, or at least dent it.

Compress any new Tamiya diff spring with a pair of pliars (it does show you in the manual to do that too, I think)

Thanks for the help guys
