Franko, so assuming you're running part 19804570 from the DB02, have you also upgraded the pinion and ring gears on the diff end? I just worry about transferring the failure points into the diff cases.

I have never had a single failure. Anytime I've taken anything apart for one reason or another, the parts looked new, and the drive trains are very quiet.

Without being a jerkface about it, I think most of these failures are user originated. Unlike a belt, there is a right and a wrong way to set up a ring and pinion or miter gears. The miter gears are very difficult to set up. Before my TB04 turned a single wheel, I bet I had 20 hours into getting the drive train shimmed "right" - what the factory recommends is OK as a starting point, and might be OK for some users, but it's not "right" because too much end play remains. If I had to do another one, I could do it in about two.

Were the steel gears more noisy or less noisy than the plastic ones when they were new?
The ring gear is put shim where the manual states right. I just put more until no rocking in that shim thickness direction. The pinion gear i put shim behind the pinion as well as behind the e-clip also until no rocking in the shim direction. Then I check no rocking and put aw grease moderately. But how to control the contact depth. Because there ain't much space to add shim and still can do assembly. Will Carbon gear case easier to shim.

I believe metal gear gives lesser noise. And sounds nicer.

There is standard steel diff gears built for tb04. These should be easier to replace. Google where to get steel ring and pinion is harder. So far I still cannot get any. Can only keep spare carbon ring and pinion as replacements. If you know of some place to get them. Please let me know, thanks

Any chance you provide some pointers to correctly shim them. Looks forward to learning from you. Thanks.

the Pinion and the ring is not an issued. I have an extra miter gear for you to buy. Cause they come in as a set of four miter gears in the package..
I did upgraded the pinion and ring gear as well. Which it didn't need to..

Can you share where you get upgraded pinion and ring gear (part number if any). Are they carbon or steel.. Thanks

Default TB 04 V11

Hi guys,

I am running 21.5 motor for GT3. To get the FDR down I use an exotec motor mount with 52t pinion. I added a shim from the motor mount side to make the pinion and spur gear line up. The problem is when I tighten it the top shim is hitting the 52t pinion. I wanted to shim the motor side but its impossible to shim the bottom screw.

How does anyone solve this? Btw I tried to upload a picture, but it failed.

Thanks

Is the pinion as close to the motor as you can get it?

Hi CraigMBA,

Yes it is as close to the motor as possible. I think when I tighten it the exotek spacer slip and move up a little bit. Causing the shim to hit th pinion. If I loosen up 1/10 turn it doesn't hit. Did I overtighten it?

Without the spacer/shim only half of the pinion and spur line up. Little contact

I am using a CRC 52T pinion. should I use a different brand pinion?


Thanks
Danny

I discover the problem. It was the motor..I used an LRP X20. there dimple on the motor causes the pinion and spur gear alignment problem. I used another motor and its fine now

I'm using the hobbywing xerun v10 motor with the exotek motor adaptor on my tb04. My motor also has that 'dimple' if you look at the picture but I'm still able to get the pinion and spur to mesh perfectly without any problems. However, I'm using no shim and I use robinison racing 52/73t 64p gears
