Spur gear tooth count

[nitrobasher]

My Revo 2.5R has one tooth missing from the spur gear...I'm shopping spur gears and seeing a lot of diffrent tooth counts...I don't have my Revo with me right now to count the teeth...anyone know what the factory count is?...and also...what would going to a lower or higher count do?....if it would even mesh up....thanks

thats funny cause i dont even remember what was factory on my slayer either, if you go on traxxas.com and click on your model, and view downloads,parts lists, and exploded views all will be revealed to you, and changing spurs, changes gear ratios, its fun to experiment, i switch between 38, 39, and 40 tooth gears on my revo and slayer, and i play with different size clutch bellls also....

p.s also the manual tells what spurs, clutch bells, etc are factory, if you dont have one you can download that at traxxas.com also....

Thanks for the help........it's the 38t i need. Slayerbasher,(or anyone), if i had a diffrent count, could i still use my factory clutch bell? I can grasp the raito change aspect....I'm thinking about cb/sg tooth mesh.

Yes you can use the factory cb. All you have to to is reset the mesh.

All you have to to is reset the mesh.

How would you reset the mesh?

Loosen the two bolts that allow the engine to rock back and forth and set accordingly. www.traxxas.com will have your manual.

The bigger the spur gear = quicker take off and less mph. smaller spur = more mph

along with a spur gear he needs more cowbell!
