Chewed up pinion

[CAGE410]

I was wondering if this has happen to anyone else with there pinions gears. It looks
like Jaws was chewing on my pinions like bubble gum. Is there something that im doing
wrong or is this mormal wear and tear. Its the pinion in the center.




Thanks..

you wouldn't be using a metal spur would you?

that thing looks like a sprocket for a chain drive now

[jay janak]

WOW are you using 32 pitch pinion gears and like iamsuperbleeder stated you using a metal spar gear ???? I had metal gear on my mini losi hate them. after i removed the metal gear

No im using the plastic traxxas 52 spur on a 3s. that pinion is or was a 19.. do you think the mesh is to tight
i tried the paper method and the feel method.. im confused

[jay janak]

Use a wax paper in between the gears them tighten the motor This works for me.

[Koda Dank]

it might be your gear mesh mine has been doing that ever since i switched to 3s and im pretty sure it was the mesh but i think i got it this time around just havent checked yet

[CAGE410]

Ill try that tomorrow im getting some new wheels in the mail.
also that spur lasted me a month all i do is bash i thought i was
light on the trigger. lol guess not..

Never seen it that bad. The pinions are steel, right? They don't look like the hardened version though.

[iamsuperbleeder]

I've always used regular paper, a thin strip folder over to double it up, and the mesh seems to be dead on every time

I have had that happen. It was the combination of a tight slipper and gear mesh to tight.

I minced an aluminium spur gear on the first run I used it on. I thought it would last longer but looks like I'm back to plastic now.

I Forgot to mention that those opinion gears are fRom Robinson Racing. When i had to change the gear i had to replace the spur also
i thought they were the strongest material for gears. I bet it might be my meshing Im hoping its my meshing. LoL
Either way Im just glad its an inexpensive part. I still like the Robinson Racing brands.. Thanks all for the advice

Just to be sure, check your motor plate and mount as well to see if it isn't cracked and that your motor alignment is good.

TallGuy I finally got around to working of my Rig. You where right on the money!!! As im cleaning
my slash i noticed one of the screws that holds the motor to the motor plate was loose
i could move the motor up and down alittle so that was allowing the motor to have a
tight and loose mesh causing my pinion to look like JAWS was chewing on bubble Gum
i tried to tighten up the screw but the head is stripped. hopefully good old BLUE can help
me out if not ill have to get creative.. Thanks Tallguy and everyone else for the help.....

Glad you found the problem!

i just ran into the same problem screw was loose . i was able to tighten up the screw(seems like those heads strip easy) had a hard time getting it back but did... only problem now seems like motor isnt align just right. when i spin tires the gears roll and studder stop then roll again.. should i adjust gear mesh?

[Shaky17]

Try Robinson racing absolute pinions.

Yeah before you do that make sure that the motor is snug to the plate. Then mesh it up
If the motor is loose on the plate you'll never get a good mesh plus you'll tear up spurs
And pinions like crazy. As for the striped screws try to find a different size what i mean
by that is try using a mm wrench or a metric wrench so that its a snug fit. I kept striping
Screws cause i was using the wrong wrench it would fit but not like its suppose to fit..
No more striped screws.
