Default Rear axle bearing keeps shredding

Hello wise folks,

I have a recurring issue where the left hand side rear axle bearing keeps shredding. It happens every 2 meets or so.

Has anyone else experienced this? Or do you have any tips on what might be causing it?

Thanks in advance.

It has not happened to me but I suspect a bent shaft. Or the motor box needs rebuilding.

Does anyone use the Aluminum Motor Spacer, 54129 with the VII?

I don't. Trf101 came with it and I don't have use for it.

You'll probably need a long shank pinion. I had the motor spacer come with my F104X1. Ended up not bothering with it after using it once. Plus on the V2, you will probably hit the other end of the bulkhead since there is not much room. The TRF101 has a wider pod so it can get away with it.

Not surprisingly, it's a Sy Brand chassis kit.

The manual for it can be found here.

Does this occur after hitting something?

have you got any movement from side to side with the rear axle, if you don't have a bit of play and you tighten up the left side hub hard against the bearing you are putting a lot of side pressure on the bearing.

Default Ride height adjusters?

Just ran my vII for the first time yesterday, love the car.
Got it to run F1 at this years IIC, and since last year the contolled tire was Pardus, i got a set of those to tune on carpet.

However, the diameter of the Pardus tire is 64.2mm vs most others in the 61mm range, and so i'm as low as i can go on rear ride hight at 5mm, with the stock spacer on the bottom and the 2mm spacer up high.

Does anybody make a spacer larger than 2mm for the Tamiya car? LHS didn't have anything.

I can't imagine people ran this high of a ride hight at IIC last year, any ideas?
Thanks.

Hey guys, i had my first complete race with my F1 yesterday, went from no grip in my last meets to winning my race after reading all of the tips on here, and watching all of the videos for the rear pod.

Now i need to add front grip lol I tried Ride R1s, and Pit Shumi 577 and 573, the car would push in turns, under power, and under braking. I don't think it's my tires anymore.

my front is at 4.5mm high, rear 5.5, i tried little droop and a lot, barely any change. I went from 2 degrees of camber, to 1, the tires are wearing evenly across the surface at 1 degree. I have 2 degrees of Toe out, with the Tamiya Silver spring, and to stop the bouncing i use AW grease from tamiya.

How do the offset front axels affect? Can we adjust Caster with the stock F104 arms? should i consider the exotek arms?

Default front end

Hi, maybe you can consider the front end of the new F1 (TRF 101). I think it gives a better control of the front of the F104.
there is a subject in which we talk about on this forum.

On asphalt try pit 571 front, 572 rear. The 571 are softer then those you listed and should give you more steering.

Trailing front axle makes the steering less responsive/sensitive.

You can get reactive caster by putting spacers on the two top rear ballstuds. The caster will go more towards zero degrees as the suspension compresses. It's not possible with the stock setup if you just want more static caster.

Offset axles will make your car less reactive. This is good for asphalt or big open tracks. Inline is better for tight tracks and/or high traction

With the stock Tamiya front end, the less camber you run, the more caster will be in the car, as the top arm is pushed out to stand up the tire. At the same time the kingpin is pushed back. The shortest ballstud in the servo (rear) end of the top arm will also get more caster, but will reduce dynamic caster effect under roll/brakes.
