Pinion Gears for 3.17mm shaft motor?

[westers]

I'm going nuts here trying to find gears to fit a 3.17mm motor shaft. Can someone please point me in the direction of a supplier.

Thanks

What motor is it? They usually take a standard pinion size?

[Jamie.T]

STD 1/10 car pinions use a 1/8 shaft (3.175mm), but these are called 3.2mm to round it off. Any STD 3.2mm pinion will fit your 3.17mm shaft without excessive play.

Hope this helps.

Cheers all.

It's a Fusion Exceed 10.5T motor - shaft diameter is 3.17mm

[Robbiejuk]

Yeah that will take a standard sized pinion mate.

Are these RW Racing pinions a standard size? It doesn't say anything in the description.

Oh, and I'm running a 78 tooth spur gear (Associated B4), so I assume I need a 48DP pinion?

Yeah they will do the job. And yes you do need 48dp for a b4 spur.

I have RW pinions that are at least 15 years old that I still use. They are good stuff. Stear clear of the titanium pinons though as they don't take kindly to sand and grit. Good old fashioned steel ones work well.

Cheers mate, much appreciated.
