Time for a new pinion and spur gear.

It's new I just assembled it

No, it's not normal. You have the motor mounted in the wrong holes.

looks as if motor has incorrect gear lash. put a piece of paper between gears b4 u have to loosen motor screws now move motor closer to spur.

The motor doesn't adjust that way. It has a series of holes in the motor mount for different pinion/spur combos. He has the motor bolted into the wrong holes.

Match the holes to what ever your pinion gear count is.

 

[tntpoof]

do as I said then line up correct holes.

Do you have a TT02?

Pretty sure Kevin knows what he's taking about...don't you have several heavily upgraded TT02s?

Two. But TNT has done a lot of racing, so was curious if he has one to see what he has done to his.

Yeah, I remember you showing me a video of one of yours in one of my threads a couple of months ago. TBH I thought you were disagreeing there with TNT, saying that he got it wrong. Problem with the internet is you can't actually tell what tone people are saying stuff in, and you can't see their expression so you just have to guess and use emojis! Never knew that TNT raced...

The only problem with what he said is setting the mesh is done with the alignment holes. There is a slight bit of play to adjust it, but not much at all. On mine, it has countersunk holes, so the screws locate the motor. There is no movement whatsoever. Even the motor mount to the chassis is a snug fit. So you are at the mercy of the hole positions for your mesh. There are cheap China brand mounts that have a slot for the motor, but the Tamiya ones do not.

I see, so you don't have much adjustability, you just have to hope the holes aren't off? How do countersunk holes help locate the motor? I have a countersunk motor mount and countersunk screws on my buggy. So some motor mounts have slight play on the chassis, so you can adjust your gear mesh further?

Doesn't Traxxas also like to use that system, where you look at a chart, find your pinion size, then screw the motor into the right holes, or sometimes Traxxas uses a pin-and-hole system?

I know this is always dough the responder and I get it . I've only repaired tt02 an sold a few nib..I've had predrilled do the chart thing but dint like my only gear option's wanted my fdr different.so I have long grub screws to put in moto and try to lineup 2 holes with correct gear mesh.. then I break out my universal dremmel tool and 200.00 bit and go to work. I got no problem make a hole longer to accommodate a screw n head

Dremels are super useful! One of my friends actually bought and sent me a new one (around mid-January), it's not made by Dremel, but it's very similar, as they are both rotary tools. I'm probably going to do a post on it sometime.

My motor mount didn't need ground. It has perfect mesh just locating on the holes. But mine is from a TT02R version. They are hard to find.

Thank you very much for your help, it was not mounted in the correct holes.
