Ta02 Pinion?

[agentsmith23 0]

I need to get a new pinion gear for my TA02 chassis truck. I have read that it needs to be a 48 pitch and between 16t-21t. However I have seen that there are different versions of 48 pitch, a metric and standard version. And I've also read that you can only run tamiya pinions in TA02 chassis.

Here is a link to where I read some of the info: http://forums.radiocontrolzone.com/showthread.php?t=17145

Can anyone confirm for me what will and won't work for my truck. The shop I have easy access to right now doesn't sell Tamiya parts so if something else will work that would be great if it won't I guess I will be waiting.

Thanks,

Dave

Hi,

i believe the pitch you need is metric 0.6 not 48 dp for the TA01/02 cars,to select the correct pinion it will depend which spur gear is fitted and the revs of the motor.Standard spur is 74 tooth and skyline speed tuned option spur gears are 66 and 69 tooth IIRC.

You should not put links to other peoples Ebay adds here on TC,it is against the rules,i will send you a link for standard pinions,there are some on Ebay,put Tamiya pinions in the search.

Pm on way.

Is the ".6" a European way of measuring the pitch? The reason I am asking is because it seems like all of the sites I am finding that sell .6 pinion gears are European all US sites seem to sell 48 pitch or some other number with out a decimal point. This whole pitch thing is making my head spin! I just want to make sure I get the proper gears for my car so I don't have to replace my pinion and my spur gear.

***EDIT***

I have found a site that sells them here in the US: http://www.carttonic.com/catalog/index.php...mp;pi_id=150452

Towerhobbies also sells a few but they aren't the size I'm looking for.

Thanks for the help!

0.6 module is an international specification for gear tooth size, much in the same way almost everywhere in the world uses millimetres, metres, litres, etc. The US is holding out with inches, feet, pints, etc, and that includes gear teeth which are still measured in diametral pitch, shortened to DP or just pitch. It's the same reason why every non-US made kit uses 2mm, 3mm and 4mm screws, while US made kits use 4-40 and 5-32 screws.

In the US Robinson Racing sell 0.6 module pinions, and they are much better than Tamiyas own. So US modellers have some idea of the size of them, Robinson Racing call their pinions "metric 48", rather than their proper tooth size, and they are readily available in the US.

To be pedantic about it 48dp is roughly equivalent to 0.5 module. 0.6 module, as used in most Tamiya cars, is equivalent to about 42dp.

So is 42 standard, metric 48, and .6 pitch the same and interchangeable?

[terry.sc 16]

Metric 48 and 0.6 module are the same size and interchangeable. To be exact, they are equivalent to 42.33dp, not 42dp.

Is there a way to tell if a gear is 48 metric or dp? My local shop is telling me they have 48 and he isn't sure which it is.

[terry.sc 16]

If the shop is saying they have 48 pitch, then it will be 48dp and unsuitable. Only Robinson Racing call theirs "metric 48", and that will be written on the header card of the bag it is in.

If they fit the "metric 48" pinion against a normal 48dp gear, apart from the 48dp gear teeth being visibly smaller it won't run smoothly when you roll one gear around the other.

Yeah it wasn't smooth at all! I went and saw it and it was definitely 48dp. He ordered the tamiya 16t and 17t set for me and it will be here Thursday night! I also had the guy look at my motor because I had a feeling it was dying and he confirmed it. The armature looked slightly burnt at the top of the windings and I bought a "Team Orion Havok 19T". I really didn't want to spend much and I wanted a modified motor. It was $22 is this a good motor?

The Tamiya #50354 16T,17T AV Pinion Gear Set are 0.6mm alloy pinions and will wear very fast, which will also damage or destroy the spur.

The Robinson Racing part codes for the 0.6mm "metric 48dp" are RRP1116 and RRP1117. Thier numbering system is quite easy to follow. the 18T is RRP1118 and 19T is RRP1119 if you can see the pattern. These pinions are steel and will last for years in normal conditions.

The RRP0116 is the true 48dp pinion part code (Note the 0 instead of 1). 48dp fits US made cars (Losi, AE, Traxxas etc).

How fast are we talkin here? Just a few runs, days, weeks, months? I currently have a 21t, I think it is a tamiya pinion it appears to be aluminum. And It meshes really well and there isn't any wear showing on it or the spur at this point. When I do run the truck I do tend to run it hard.

[TA-Mark 195]

Fast as in lucky to see 30 runs, for me that is 2-3 weeks, so fast. (1 Li-Po pack with the brushless and it's gone)

I haven't worn a steel one out yet... and it's been 18 months since I started using them. The oldest one is starting to show signs of wear now, but it's had a season of racing on it with a MambaMax 5700Kv pushing on it, and much bashing/practice (sometimes 4-5 packs a day). I'm going to replace it within the next few weeks so it doesn't start to damage the spur.

21T is too tall in a TA02 truck. 19T is the ideal pinion with a silvercan 540 on this wheel size, anything hotter needs 18T->16T pinion. I use 16T and 17T pinions with brushless 4600Kv/5700Kv in the TA-02 truck.

I have the 16-17t Tamiya set coming in tomorrow night and hopefully it helps with my battery and motor heat issues. Do larger pinions do better for wearing on the spur? Because I don't see any wear at all on the pinion or spur.
