Gear pitch??'s

[jessnlaurie]

Is it possible to use a 32p motor pinion on a 48p spur,or do they both have to match.Do they even make a 32p spur?
Thanks

They have to match if you want the gears to last at all. Yes they make a 32p spur gear. The one in the picture is from a Traxxas Rustler




Here is a Robinson 48p spur



They are close to matching but they will not work together, might last a few minutes but thats it.

Is traxxas my only option if i want to go 32p?Or are there others to choose from?

[RD400]

What are you using it on? Are we talking metric 48P or standard 48P?

[jessnlaurie]

It may go into my PTI,not sure If they are metric or standard.I've been debating on weather to go 32p or just use the stock gearing and using a 65t lathe motor.I may just try the latter,cheaper and easier.

[RD400]

How many teeth are on the PTI spur? It should be standard pitch.

sorry for the thread jack ,here goes, i know the traxxas spur is 48 pitch and the tamiya are also 48, are they standard or metric, i couln't seem to mesh the tamiya 16 tooth to the traxxas spur

[RD400]

Traxxas=standard 48P

Tamiya=metric 48P

thanks RD, i knew there was something wrong there
so what spur should i buy for the stampede tranny? i mean to work with tamiya gears?

[RD400]

Ditch the Tamiya pinion and get some Losi 48P pinions. They are made of steel and run really smooth. Robinson Racing makes some nice pinions and with them you can get a 12 tooth, 48 pitch pinion.

i knew i should have asked first , i have over 10 0r 12 gears, different tooth count, i guess i will look into the losi, i do have a couple of robinson though.
