Pitch is the literal pitch of each tooth in relation to the other. Tha main idea is that you match the pitch between the spur and pinion, if you have a 48 pitch spur, buy 48 pitch pinions, or if you have a 64 pitch spur, then get 64 pitch pinions.

Look under where it says on the left
UNDERSTANDING “GEAR PITCH”.

As was stated be sure to use the correct pitch, meaning use the same as you have when replacing one gear.

Thanks

EDIT: Edited to correct the html link

basicly its how big the teeth are on the pinion or spur gear.the higher the pitch the smaller it gets.just think what would happen if you put a pinion with small teeth on a spur with big teeth,wouldent work would it?no

Sorry.......link corrected now

http://www.abslotsport.com/page8.html

You have to put the l on.........dumb me did not copy the link correct.

The easiest way to explain it would be like a nut and bolt. Some have coarse threads (32 Pitch gear) while some have fine threads (64 Pitch gear). You can not screw together different thread types any more than you can use different pitch gears together. Usually coarse gears (32p) are intended for extremely powerful things where you need as much teeth contact surface as possible to stay together. While rc cars and some trucks can use 48p gears and survive fine.

Thanks

Can anyone tell what pitch [link=http://www.horizonhobby.com/ProdInfo/SWK/250/SWK5092-250.jpg]this [/link] pinion gear is? It is the one that came stock on my Raven ST. I am looking to replace my pinion, and want to make sure I get the right one/ The item description only says: 20 T Pinion Gear.

Thanks for any help.

Looks like a 48p to me, might be 32 but I really doubt. ST's generally run 48p!

Looks like 48 pitch . The best way I found to describe pitch is like on bigger gears is TPI [teeth per inch] .
