Kpowell911 Posted January 16, 2022 Share Posted January 16, 2022 Hey guys. Having an issue with my Maxx. Got the following set up: Traxxas Maxx Vitavon Standard Servo Mount Treal Aluminium Bellcranks Noble NB4 Radio Savox SG2292 Servo As you can see, a no expense spared set up: BUT every time I turn left or right, I gradually lose steering lock. After 3 or 4 turns Im only at 10% lock? The servo (metal cased) gets RED HOT. Ive rebuilt the steering multiple times. Ive put brand new bearings in the bellcranks, Ive checked for binding in the steering train. With the power off I can physically (easily) move the wheels to full lock. Yet under power, the servo gradually loses its throw angle. Its almost as if Im manually turning the EPA down each turn. EPA has been changed to various different settings, and it still deteriates Theres a chance its a radio setting, its far too complicated, but its as if Im only getting to use 30-45 degree’s of my servos range if that makes sense, and the servo is getting red hot as I say. any ideas? Im stumped! Quote Link to comment Share on other sites More sharing options...
supersavage Posted January 16, 2022 Share Posted January 16, 2022 (edited) Only thing I can think of is you have a bad servo unfortunately. Do you have another one to test to make sure whether it is the servo or not? Edited January 16, 2022 by supersavage Quote Link to comment Share on other sites More sharing options...

Decided to try a brand new Power HD servo, intended for a Rustler so not good enough for the Maxx but will ‘sort’ the issue. However half way through I found there WAS some binding in the Treal Bellcranks. I cant see how or where, but the binding has gone with the stock plastic bellcranks back in?? 1 Quote Link to comment Share on other sites More sharing options...
Stormbringer Posted January 16, 2022 Share Posted January 16, 2022 Have you tried it with the savox servo back in ? 1 Quote Link to comment Share on other sites More sharing options...
supersavage Posted January 16, 2022 Share Posted January 16, 2022 Maybe the binding ended up being a little too much for the servo and is causing it fail. Could it be the tolerances on the treal bell crank be to tight that a bit of unseen debris cause it too bind? Or perhaps just general dirt build up when running it might cause it to start binding then when you clean it you don't really notice anything. 1 Quote Link to comment Share on other sites More sharing options...

Kpowell911 Posted January 17, 2022 Author Share Posted January 17, 2022 Everythings fine with the stock bellcranks back on. I cant formthe life of me find any ‘issue’ with the Treal one, but for whatever reason, it binds 🤷🏼♂️ 1 Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted January 17, 2022 Share Posted January 17, 2022 Can you stick a washer under the bearings at the bottom/up on top to stop it binding? Maybe some fine tuning with a file/sandpaper? Quote Link to comment Share on other sites More sharing options...
Ross9999992 Posted January 17, 2022 Share Posted January 17, 2022 I guess with it out of the truck it’s not binding on the other joints? Quote Link to comment Share on other sites More sharing options...

Ross9999992 Posted January 17, 2022 Share Posted January 17, 2022 Well it should be easy enough to fix. If it’s fine out of the truck then it’ll be top or bottom of the steering posts most likely. Maybe it was supposed to come with some shims (washers). Maybe the bearings are too thin. Maybe the tolerances are off and when tightened down the plastics of the truck flex and rub. I’d say washers top and/or bottom are the quickest/easiest fix though without any actual modifying. Maybe the servo arm hole is too deep and binding on the servo itself?
