I know there are three types,32P,48P,64P. But, i never knew there was Standard and Metric Pitch. So, when I go to the LHS and ask for a 23T 48P pinion...why dont they ask if its a metric or standard? I know this has probably been covered before, but is there a site with Pitch information and details? Or can somebody explain to me with pics? Can a metric pinion be used with a standard spur?

These are two 23T 48P Pinions.One is metric and one is standard?

Doahh

silver is metric... it's a tamiya pinion right? the pitch is VERY SLIGHTly different and will not work =(

I thought metric would be smaller? I was thinking the silver one is standard and black is metric.

Rare

Silver pinion is 9/16inch and the black one is 1/2inch....

Rare

.6 is metric 48P pinions...

Could anyone help me out?

The part that confuses me is pitch equals number of teeth per inch of diameter, correct? So if that is so then as far as tamiya is concerned it can not be the same thing, as they do NOT use the inch scale but meteric. So that would explain their way of saying meteric 48p because they are speaking in one language and we are accustomed to 32p, 48p and 64p being all the same basic starting point which would be back to the 1 inch diameter and they use meteric as a way of measuring, which all other manufactures use the one we have been using for years.

So I hope someone with LOTS more knowledge than me will step-up and EXPLAIN it so we will know what the truth is.

I am not looking for "He said or she said or I was told" but someone that can point to the facts as a way for ALL to get a better understanding.

Thanks

Dudelive, i thought i was all alone on this! Good to know im not the only one. Robinson racing also makes 48P Metric pinions as well...Id just like to know how to identify them and tell the difference. And why is it that my LHS never asks me if I want metric or standard pinions?

theres also 16 pitch gears used in the large scale buggies... liek the HPI 5b and traxxas monster buggy...as far as metric and standard... im in the dark also

Rare

Im not really concerned about large scales...thanks for the info though! Good to know. Now, i know there is somebody out there who knows about all this!!!

Doahh

tamiya have bigger farther apart teath... I know... I own tamiya and losi cars

Rare

So, tamiya and robinson racing are the only ones who use metric?
