Default TC3 Pinion Gear Mesh Adjustment How ??

Hey guys, just got my TC3 I think the mesh is off because it slips sometimes and sounds horrid. Can someone tell me how to adjust the gap? Thanks

There should be 2 screws on the heat sink. Loosen them and move the motor closer to the spur.

Don't forget to re-tighten the screws.

You should be able to slightly rock the spur, try this in several spots with out moving the pinion.

Another way is to put a cigarette paper between the spur and pinion and just move the pinion up to the spur and tighten motor mounts, then just rotate the paper out and it should be the perfect mesh.

I just do my first suggestion & never have any probs with mesh issues.

Good luck

Cheers

I figured out how to adjust it, I put a piece of paper between the two and pushed it together then tightened it down to AE specs (gap, etc.) but it still isn't catching well, the pinion spins freely sometimes. Do I need a new spur gear?

Is a piece of paper good for the gap?

This question requires a little more info to answer...

-press the gears together

-pull the mesh barely loose and tighten the screw on the inside of the motor mount(heat sink)

-the screw on the outside that has a spring on it : tighten it only enough to put some pressure on the spring(do not overtighten)

-check the mesh by rocking the spur back and fourth, feeling the gap

-again make sure you only have a tiny amount of space between the gears

good luck!

Ended up being a stripped spur gear that kept me from getting the mesh just right. Gotta pickup a new spur gear
