Teddy it's because the track was filthy. If we were on clean surface they'd be fine. My touring car took a beating on the gears Sunday

If the teeth look rugged it can be a little too much play.
Adjust with a piece of paper pressed between the teeth and messure if it was indeed more. With giving the wheels a turn the spurs will turn also without much noice normally with new spurs. Check the bearing play on the clutch pressing the pinions apart from the spurs. Check the tranny axle play the same way. Check play on the plastic bearing holders, glue them if neccesary.

Maybe just little debris , stones on the track? like mentioned.


Hope it helps you, have fun.

Does anyone of you have the same problem and what can I do - appart from using the plastic bracket because it will eliminate the vibration because it is weaker.
It doesn't break because I crash.
Anyone know of a fix?
Do we need to stay away from the alu radio bracket?

Thanks!

There doesn't seem to be a serpent specific pinion gear removal / installation tool available.

Any recommendations? perhaps the Mugen tool works?

Appreciate!

Serpent still lists the molded pinion wrench , part number 909590 , guess mine might be 10 years old and still works just fine.

When you say it spins are you talking about it does a donut when going into a turn or the drivetrain is still spinning even when on break?

I would suggest you start by getting lossening up on the brake nut on the throttle lever so the car has less brakes. Right now it sounds like you have too much brakes and is a little too sensitive. If you loosen it up a little bit it will make the car a lot more controllable when braking.

I also use a longer piece of fuel tube on the linkage to take some of the bite out of the brake. Basically it allows more servo movement before the brake locks.

This is because you brake too much. I had yor same problem, and i solved changing the brake disk with mugen mrx5 one and setting again the brake. Also other italian serpent drivel (like Mazzeo, Tedeschi, Piromalli...) did this. It fits quite well, you may just look after how it fit on the solid axle, and you brake pads must measure 1.8mm (measuring steel + ferodo) or minus else the disk will not enter. No big problem anyway, and it is not very expensive
