obeykube Posted January 19, 2014 Posted January 19, 2014 Hey guys, just finished book 2 of 3 of my set and obviously wanted to try it out before putting the body on. I can drive forwards and backwards perfectly, and I can turn right, but turning left is an issue, the car just won't do it, and it doesn't even sound like the engine is trying to, and if I manually push it, the car does seem to be able to turn left. any ideas?

JM1971 Posted January 19, 2014 Posted January 19, 2014 Sounds like the servo needs to be centered, try and move the black cogs off the steering rack then power the servo so it centers itself. Quote
obeykube Posted January 19, 2014 Author Posted January 19, 2014 even just with the servos by themselves, they will only turn in one direction. Quote
Junpei Posted January 19, 2014 Posted January 19, 2014 (edited) Just contact LEGO Customer Service- unfortunately you got a faulty servo motor. It actually might not be a faulty servo motor- like JM1971 said, you should probably check the batteries, etc. first. TLH Edited January 19, 2014 by TwentyLeggedHen Quote
JM1971 Posted January 19, 2014 Posted January 19, 2014 Check batteries are ok, if not then connect the servo to another channel to rule out the transmitter, then straight to the battery. Quote
OzBen Posted January 19, 2014 Posted January 19, 2014 I had a faulty servo in one of my 9398's Only went one direction just like you described. Lego customer service replaced it without hesitation. Quote
DoomedACE Posted April 5, 2017 Posted April 5, 2017 Sorry for the necro bump, but opening a new thread does seam suboptimal either.... Ist there a way to change the servo in this model, without taking it apart fully? mine died a week ago and nie the replacement has arrived... any help is greatly appreciated! thanks! Quote
JJ2 Posted April 5, 2017 Posted April 5, 2017 Whats wrong with your servo? does is only turn one way or not work at all, or get stuck? Quote
TechnicRCRacer Posted April 5, 2017 Posted April 5, 2017 Have you tried that receiver port with a different motor? Quote
DoomedACE Posted April 6, 2017 Posted April 6, 2017 (edited) It does noting at all, unfortunately. Not even making a noise. And yes, I've tried 3 different receivers with that motor. And different motors on that port. The port on the receiver is fine, it is definitely the servo that is dead.. :-( Edited April 6, 2017 by DoomedACE clarification and spelling.... Quote
JJ2 Posted April 6, 2017 Posted April 6, 2017 Is the wire damaged near where is enters the servo? I would recommend opening it up with an Xacto knife then checking the inside. Quote
DoomedACE Posted April 6, 2017 Posted April 6, 2017 I'll probably do that, but to achieve this I first need to get it out, thus my question: "can the servo be removed from the chassis without taking it apart fully?" Quote

Expand Ok, you will need to take it apart, I don't think taking apart a 9398 will be very difficult though. For taking the servo apart you need to cut the plastic in front of the DBG clips to allow the DBG part to slide out of the LBG housing. Don't try to push the clips to disassemble it, it want work, I tried. Quote
DoomedACE Posted April 7, 2017 Posted April 7, 2017 Thank you, will give it a try next weekend.... Quote
