Hi this is my first post i have a tmaxx with a trx pro 15 engine in an it kept stripping spur gears so i bought a steel spur an now its stripping the clutch bell gear does anyone know how i can prevent it from doing it any help will be much appreciated atb ade

probably aint meshed right

Have you got any tips on how to do it iv tried putting a piece of paper between them an it did last longer but still stripped n about an hour or so

You have to use a Hardened Steel clutch bell when using a steel spur from what I've heard.

Ok thanks ill hav a look on the net for one or see if my local engineering shop can harden one for me atb ade

look into robinson racing gears

What brand of steel spur gear do you have? if it's Integy, thats the problem.. tried them last year and went thru a clutch bell per race.. lhs had alot of issues with em also..

Iv been using traxxas ones mate

You have to push the whole gear into the spur as tight as you can get it with the engine and mount as straight as possible. Then you want to back the gear out of the spur keeping the engine and mount as straight as possible just enough to let it spin free with no binding.

Basically you want as much tooth biting the spur with the least amount of binding. Almost sounded like you were using 2 different gear pitches
