mrhavana Posted October 2, 2012 Share Posted October 2, 2012 Also know as DP, you get 32dp, 48dp, 64dp etc. Just has to match up with your spur gear. What car is it for? Quote Link to comment Share on other sites More sharing options...

mrhavana Posted October 2, 2012 Share Posted October 2, 2012 I meant what car are you intending to use it on? Look up the specs on your car and see if you can find a reference to dp. Quote Link to comment Share on other sites More sharing options...

jonnotheone Posted October 2, 2012 Author Share Posted October 2, 2012 What does the pitch mean lol is it like the width or summin.???? Quote Link to comment Share on other sites More sharing options...
mattr Posted October 2, 2012 Share Posted October 2, 2012 Its related to the size and shape of the teeth on the spur/pinion. If you use a mismatched pair, you will destroy one or other of them. What car are you running it in? What pitch is the spur gear? Quote Link to comment Share on other sites More sharing options...
XV Pilot Posted October 2, 2012 Share Posted October 2, 2012 (edited) Strictly speaking, pitch refers to the angles used to create the tooth profile on a given gear. However for our purposes, we can think of it as a number referring to how big the teeth are. For your spur gear and pinion gear to mesh properly without grinding each other into oblivion, they should be of the same pitch. The merits of different pitches is something that can lead to spirited debate between hardcore engineering types, but for our purposes, all we really need to know is that gears of the same pitch work together, while gears of different pitches tend to destroy each other.

mrhavana Posted October 2, 2012 Share Posted October 2, 2012 the car or the pinion....the car is hsp well a hsp highbreed.. the pinion is unknown lol Try and help yourself a bit! What car does your spur gear originally come from? Make and model would be useful. Then someone might have a chance of telling you what pitch gear you need.

suicideneil Posted October 2, 2012 Share Posted October 2, 2012 the car or the pinion....the car is hsp well a hsp highbreed.. the pinion is unknown lol Post a picture of the pinion and spur gear, maybe with a ruler for scale next to them ( decent, bright picture on a white background ); us old dogs can more than likely make a visual determination for you if you have no idea yourself.
