HI

Would like to enquire....

How come my Spur gear (from Xenon) keep wearing off in 1 ride? Is it suppose to be like this or am I doing it wrong somewhere?

Thanks.

Try some other spurs, i've never liked Xenon spur gears, their pinions are superb though.
Some other spurs to try could be RW, Kawada, PRS or Kimbrough.

i wonder... is it cos i placed it too near the pinion?

Probably because the mesh it too tight, or too loose. Also, a badly worn pinion will wear out a spur quickly too.

Are you running the same pitch on the pinion and spur gear ? Had to ask.

yup... 64 to 64...

mesh too tight? means to say its too 'close'.... can't be the pinion being worn... its new

I think it was too tight... anyone with suggestion as to how tight/close I should place 'em?

Anyway, how do I remove a e-ring? its so tough..........

Running a piece of paper through the gears to set the mesh works.

not with 64 pitch!

Make sure you aren't running a tamiya pinion. just checking since you have a tamiya logo in your avatar...

Oh, the tamiya logo is cos I am using a TRF 416 at the moment...

I'm using a Xenon pinion and spur gear...

May I ask, why is the Tamiya pinion so bad?

Bad isn't the right word, more like inappropriate for most people: its tooth pitch is different that most LHS's. I think its metric?

As long as you're using the correct pitch and mod. of pinion and spur ~ most often spur gear striping comes from either a bad gear mesh (too loose, or too tight), a worn pinion gear, or some sort of binding in the rest of the driveline.

Pick a spot on the gears and set your mesh so they are close but not touching. Most spurs are a little oblong so rotate the spur and pinion and check for mesh at several areas. You may find that your mesh gets too tight or too loose in some areas. Use these spots to fine tune your mesh and you should be good. If it's too loose, it will chip the teeth. If it's too tight, the spur will overheat and become brittle and you'll break the teeth.

As far as removing e-clips. Try using some needle nose pliers or the tip of a jeweler's straight slot screwdriver.

my most preferred method is to use a piece of paper between the pinion and spur. there'll always be a gap, but not too big. beats guess-timation on the distance between spur and pinion.

My guess is you've never seen or used 64pitch gears, or you're using tissue paper to set the mesh.
