I have to replace mine on my Ten T, but do all the rules apply the same to every car when it comes to tightening?


Do I tighten it with a piece of paper in the middle like I do on my Slash?

yep thats a good way to do it they all need the proper gear mesh and a piece of paper seems to work well

mike881

what's "proper gear mesh?"

rc everywhere

nice ten-t ... you lucky dog! back order up hear!

proper mesh ... is when the gears are just far enough apart not to bind together at all the whole turn around, causing heat and wear, but not soo lose that they just touch the tips of the teeth causing premature wear.
it's easier than it sounds but that important!

just my 2 cents but I prefer a little more space than what a piece of paper provides ... I think with all the flexing these chassis take during racing that they need a little more room to move ... I have started checking my "backlash" by hand which is to hold the pinion and rock the spur back and forth to gauge the space but this is hard to define but try using a section of plastic from a parts bag (as opposed to paper) and if anything go SLIGHTLY out from there

mike881

alright, so if I use paper, just back it off a LITTLE bit when im finished?

Jed the Geezer

The littlest of little bits LOL ... also make sure the gears are flush meaning ... when you move the gears so that a pinion tooth is close to a spur tooth they are perfectly parallel

In the end when you spin the wheels by hand you want it to be as tight as possible but still smooth to spin ... hope that explains it

the gap is supposed to be between .004"-.008" of an inch. FYI A typical piece of typing or note book paper is .004" some of the better ones are .006" and is about perfect..

All that said once you set enough of them, you don't need no stinkin paper..

I just use a piece of plastic from a parts bag, but i Love the mounting lines on the 2.0

I'll tell u the easiest way to do it, on the bottom of the chassis loosen the 4 adjusting screws that let u move the engine then tighten those 4 up so to the point where the engine can't barely move then check ur mesh if the play is to tight take a tool and stck it threw the flywheel hole and slighty pry the flywheel away from the spur. This alows u to move the engine in or out whatever way very very little making the mesh very close to what u want I like mine to have good rolling but no much noise the best way to check if it's tight enough is when u put it on the groun and check how it rolls is it has noise when u roll and then stop really fast it's loose. I let the center spur have about a tenth of an inch of back and fourth play when I hold the clutchbell and move the spur. But try using my idea why barely tightening the 4 adjusting bolts on bottom it works well cause u don't move to much or to leas everytime u adjust it and when ur done just tighten them up good.
