Near perfect , also include what pinions and spurs your running. Maybe even clutch gap or anything else you can jot down.

Thanks!

I had a stripping problem to begin with, but it is now solved (just had the engine a tiny bit out of alignment..)

The MTX3 didnt strip gears as it did not have a .8 gear mesh like the MTX4..so if you dont get the mesh on the MTX4 perfect..you will hit troubles.

I had SGS (knocking on wood), but somehow the nitro gods have been nice to me lately. This problem does happen to most MTX-4 owners. I close friend of mine is sponsored by Mugen and he even strip gears. Here's how I limited the number of stripped gears.

4mm chassis
Thread lock Engine mounts (I use the blue one)
Use longer screws for the 2 bottom engine mounts like ASW7576 posted in post #8405
SUPER tight mesh
Steel pinions
24T side pulley
Gears:
Pinion Spur
17T/T23T 53T/59T
16T/22T 54T/60T
18T/24T 52T/58T

I've ran on a soda prepped track, VHT prepped track, no prep track, smooth track, bumpy track, etc... and my SGS solutions seems to be holding up (knocking on wood), but it did cost me a lot of spurs to finally get it down right.

What it seems you're implying, is that Team drivers don't make mistakes or errors in judgement and do everything 100% correct, 100% of the time. Building a car and maintaining a car are two different things. If they let the latter slide, even a bit, even they can get themselves in trouble during the course of the race. They can also get into accidents, which can also shift things out of position, which can also lead to problems sometimes during the course of a race or subsequent races. Team drivers may be extremely good, but they are not perfect and they don't have 100% control over every aspect of their car 100% of the time.

I think you know where I'm going with this...

Can I ask what the purpose or effect the thrust bearing spacer has?

It prevents any drag on the clutch bell when idling, and mostly improves consistancy with the clutch engagement, and dis-engagement. Very clever really.

If that's the case, would you be open to the possibility, that perhaps a Team member's gear strip may have been a result of their own action, inaction or forces outside of their control (i.e. part wear, accident, track debris, pit man dropping their car, etc..)?

If your having gear stripping issues, try replacing your clutch bell bearings first.

Do not use longer screws in the bottom of the engine mount as these may not tighten all the way down. Longer screws may bottom out on the rear hole. The rear hole is used from the top to hold the motor to the mount. Only use what's listed in the manual.

Also as a side note for those using the JL red dot. I have noticed on a few of these engines there is excessive play up and down side to side from the front bearing. This crank play could also lead to excessive gear mesh causing a stripped spur gear.

The longer screws are used on the clutch bell side of the mount.

It could be anything. My point is, that a mugen driver is going to be on top of their game. Where as people are pointing out that its like novice type errors here. My point is , even the top guys are blowing them. I think you misunderstood that.
