    I can't seem to get a clear answer on this. How are you guys getting at your pinion gear for adjustments/replacements/etc???

    do you guys remove the esc and get at it that way or just leave everything as is and put a wrench in there.

    any information would be great. thank you!

    Hi

    If I am not mistaken, you have the two adjustment screws that hold the motor in place, and the set screw that holds the pinion gear onto the motor shaft. As far as I can see those are the only adjustments you have of the pinion gear.

    it's the kraton. i can barely get a wrench in there to get at the motor screws so just thought i'd ask you guys if you had any easier ways of getting at it. the manual isn't really any help

    I don't own one...But looks to me that when you take of the roll-cage off and disconnect the engine you can acces the gears...?...o_O
    But I can see this could be some nice finger splitting thing to do...:confused:

    Hi

    It looks like removing the ESC will give you more working room.

    After some examining of the expanded parts pictures en photo's I would likely choose to take the entire motor-mount out...Looks like the easiest way to do some good work on it...Well, that's my two cents...:cool:

    I did this last night for the first time, I used the provided allen key, loosened the top and bottom motor mount bolt and it was easy peasy.

    No need to remove the ESC, motor or even the roll cage.

    Who makes the best pinion gears? I hear there are certain makers that have a better cut for a better mesh?

    Just use the provided Allen wrench. No need to take anything off.

    I second both RR hardened and Novak, currently running both in my rigs, word on the street was Novak went OOB. Not positive, but LHS buddy told me that a few weeks back. This is my preferred gear. IMG_20170102_203911048.jpg

    They sell a wide range of pinion gears for these rigs. I would recommend the 16 for more speed personally. No other changes necessary, other than getting your gear mesh set. Part number is on the picture, 1216 Robinson Racing. Any brand Mod 1 gear with 5mm shaft size should work, I prefer this one for durability. Just get a temp gun to check motor and ESC temps. The temps generally increase with each size up on pinion. Stay under 150-160F tops to be safe, probably less than that for ESC.

    If,it is like the Outcast 5 screws drop the whole engine, center Diff, roll cage assembly. It is very simple from there to change pinion and mesh. Just finished putting 16 in and it took about 10 minutes. Used a hair dryer to free grub screws and pinion. Hope it is similar and this helps

    I am currently using an Arrma 17T pinion, but also not using the stock motor. Running a Tenshock motor. I haven't had any issues with the Arrma gear.
    As far as adjustment, I just pull the 5 screws out from the bottom and pull the whole assembly out. Easier than hunting for my Allen's that came with the truck. Lol.

    To me that's the only way to do it best and set things to your liking.

    Yeah. I haven't had an issue. Put some locktite on the motor screws and it should be fine. The pinion can be checked while it's in the truck.
