Default Tamiya 0.4 gears & 64pitch gears

Hi guys... I've got a load of Tam 0.4 pinion gears. But I want to run BL 17.5 and to get the right gearing I need to use a different spur and it doesn't look like tamiya makes a 80T or there about 0.4 spur gear.

Can I use tam 0.4 pinions on a 64 pitch spur gear? If yes, what will happend??

Yes, the two will mesh, however they are NOT the same pitch. An 0.4/64 mesh is just that shade rougher than a 64/64 mesh would be.

It will be noisy and wear the spur out quicker than using 64p pinions.

Nope. You might think that they are on the bench but when they are in the car your ears will let you know they are very different.

I use my tamiya pinions all the time with a standard 64 pitch with no sound or wear.

I have used them by accident in the past and it worked...but it isn't a good idea to. Though they look the same the pitch is different and you will not get good tooth engagement mixing them. Besides the possibility of increased noise you also increase the chances of stripping or damaging a gear.

I have done this with no problem. AreCee I was racing you with a 64 pinion and a 0.4 spur!

I've done the same thing, like I said it can be noisier (unless you set the mesh just perfect) and since the teeth have different profiles the softer plastic spur gear will wear out faster than if you use 64p gears.

I may still have some of those real soft aluminum pinions Kyosho included with their kits. One of those pinions has teeth pointing backwards.

Bottom line is that it can be used but your experience may differ from that of others.

Do all tamiya gears 0.4 not 64 pitch? I m about to order kawada 64p pinion going inside my new MS and my upcoming 416WE which come with stock Tamiya spur gears. Will this match? or do I have to buy kawada spur gears as well?

I think that all tamiya kits use metric pitch gears.

True, and they typically design the car to accept standard 64p spurs as well since they know that's what racers prefer.

I don't see a 28 or 29.

I will look up what I want on the tamiya site then send a note off to champ. Several people recomend them for tamiya parts, they are very hard to find around here.
