Hi Success lipo,
Do you have a pic of the failed pinion you can post?. I found after first run of Kraton after unboxing the pinion had excessive wear. I removed cleaned and inspected both gears. I use a pice of paper between the gears to set the tolerance, and have found this to work well for me. Since this time I have not experienced any further wear of the gears. I use the standard gearing ratios that were supplied. Other factors that can cause excessive wearing is excessive friction in the drive line, like seized and or broken components. Would be unlikely on a new vehicle though.
Hope this helps.
Hey guys, I'm completely new to Arrma and I am repeatedly throwing Pinion gears off my Kraton. I'm not even driving that hard so I am mistified. On my last arrma pinion gear replacement, I broke a tooth. Can yall weigh in on anything you can think of that may cause a pinion gear to slip off? Heres what I have done: I buy the pinion gear with the blue locktite on the screw, I screw it on to the beveled edge of the shaft and that's all I know. I don't' know if the top of the pinion gear should be flush with the top of the spur or the spur should be in the middle of the pinion. I also don't know how tight to make the mesh. I assume, the car should be able to coast freely....... Help
Which car do you have? Not that I have a different answer for each car, but I know my Kraton is loud as heck. Even when I just push it across the floor, with the power off. But I have never had a gear issue, and I am a terrible driver. By terrible I mean hard starts and hard stops, lots of jumps and even more crashes. And I drive on 6S most of the time. I think the paper trick is a good guide to use, when setting the mesh, but you still have to know what is too tight and what is not. Look up "Setting gear Meshh on an RC car" on youtube and watch some videos. My guess is that you find your solution. Also look up some videos of your car and see what other people's car sound like.
Red locker holding for me,when I need locker to loosen,use hot Allen wrench method to remove. Bensz torch,spare Allen wrench,vise grips. While watching TV in living room. Piece of cakeMake sure you let the loctite dry for at least 16hours before you use it.
If you do this u shouldnt have any problems with your pinion coming loose.
They should make a sealed case so you can grease the pinion and spurYou cant just make judgement on one specific situation, in this case based on your rc alone. There is another user on this forum and myself that both had premature failure of the pinion gear.
I submitted my claim through Hobbico and was sent another brand pinion gear because they are way back ordered on them, and thats for a reason.
I checked in between and after run plenty of times. Besides cleaning up, to make them last longer let them cool off, or help out by spraying every now and then a little wd40, or light silicone oil. Metal to metal gets extremely hot, and the hotter the weaker the teeth get. One cannot rule out a possible pebble, debris that allocated there and it takes seconds to shred through.
Srrange as it may seem if one really bashing, and not paying attention, it can go unnoticed missing 2 teeth, and before you know it they are all gone.
Which Robinson pinion gears do you have and where did you order yours from? Thanks.
