Maximum MT stripping counter gears

Post by RM25 » Thu, 19 Oct 2000 04:00:00



my MT likes to strip counter gears when driven hard

could this be

1. lube moving off the gears

2. locking up wheels putting too much stress on it

3. the heat from the metal spur gear transferring down shaft to the metal
gear that meshes with the counter gear, it then gets too hot and melts the
counter gear...

are any of these likly causes and how can i fix this....

cheerz...

I have an ST but have forgotten which gear is the counter gear?  Let me know
as I believe we have had the same problem.

the middle one inside the gearbox e.g. between the one attached to the spur
and the differeantial

Ah yes...  I went through four of those little bastards.

I realized that the bearing on the counter gear shaft was seized that was
the begining to the end of the problem.

I found that I stripped the gear in high stress situation.  eg. full
throttle 180s knocked out two gears and WOT landings wrecked the other two.
Back off the slipper clutch a little.  Since I have done this I have not had
any gears wrecked.

You can also look for a metal gear replacement - Traxxas has one that is
exactly the same gear but is made of some "steel".  The only downfall to the
metal gear is something else might strip - maybe the spur gear (on the other
hand, a spur gear is a lot easier to replace than a counter gear).

Finally, check the other two gears in the *** and BE SURE there are no
foreign objects embedded in the teeth.  I pulled a very small bearing from
the counter gear bearing out of one of the other gears.

Hope this helps...

You can e-mail me if you have any other questions.
