Default Steel pinion for TT-01

Im after steel pinions for my TT-01, cause im just going through alloy's. I have been told to use the robinson racing 48 pitch metric steel alloy pinions (.6 module). Is this correct though?

If you look HERE Towerhobbies says the AV pitch pinions are 48p metric. So that means you should be able to use THESE .

It is a bit misleading to call the metric 48dp, the tooth profiles are totally different, but you can use those robinson pinions.

It is a common point of confusion and i have seen many a stripped spur gear because of it. Tamiya pinions (and other makes as there are some) that have 0.6 module or indeed the fine pitch 0.4 module are not the same as 48/64dp gears. They are close and will run together for a short period of time, but not long til is knackered.

dp (with stands for diametrical pitch) is an imperial measurement and is the number of teeth of that size you can get round a 1inch diamtre gear. Module is the length in mm for each tooth on the pitch circle diametre.

for example 48tooth 48dp gear is 1 inch diametre. 48 tooth 0.6module is 48*0.6 = 28.8mm or 1.134inches

Basically 1 is metric (gear module) the other is imperial, so its like fitting a inperial screw into a metric thread, with a bit of force you might get it in, but you are screwed if you want to get it out. (sorry for the pun)

Unfortunately not everyone will learn this and gears will continue to get stripped, just dont believe everything the bloke in the shop says!!!

Would switching from a 19t pinion gear to a 21t pinion make a big difference ? thahookup Rookie Zone 5 05-19-2006 01:09 PM
