Weird sound after installing new pinion gear

[EmJayeX]

So I just got a new pinion gear set

4pcs 48P Pinion Gear 3.175mm Set Hardened 20T 21T 22T 23T 48DP Pitch Gears RC Upgrade Part with Screwdriver https://a.co/d/evuzxrG

And I installed the 23t one. I put it in and realized the teeth were a bit shorter than the stock aluminum one? So I tried the 22t position on the motor mount. It fit but was slipping a bit when there was some weight on the wheels. So then I put it to the 21t one and it fit great. 

BUT....when I started running it a bit, it sounded kinda weird. Maybe like it was meshing TOO tight with the spur gear? 

Maybe im just freaking out, and Im not used to a steel pinion?

Im not really sure and dont really want to have to buy another pinion to replace the stock one (already starting to wear out a little).

And thoughts and insight are much appreciated

The TT-02 uses metric gears. You cannot use a 48dp pinion in it. You need to buy 0.6Mod pinions for it. An example of pinion that has worked very well for me is the Yeah Racing hard coated pinion 'for Tamiya' 0.6Mod pinions. Robinson Racing also makes some 0.6Mod pinions.

You should also replace your spur now that you damaged it with the 48dp pinions.

Ahh crap, well, thanks guys. Ill make do with the old pinion (and spur 😭) until it really gives out. Probably shouldve done more research and paid attention to the listing

Will this pinion set be ok? It looks to be aluminum too, but the reviews are good

Seems more expensive then a proper YR one. Are you in the US? You can get them on AMain Hobbies.

There are lots of CR01 experts here who will be able to confirm which module the CR01 uses, if you really want to use the Amazon ones. And yes it looks like aluminum. Used in conjunction with a damaged spur... They will not last 5min.
