Senton Can't get pinion off my Senton 3s

[MJMARLOWE]

Trying to change the pinion on the Senton 3s.. took the grab screw out and still can’t get the pinion off .. also any suggestions on getting the over loctited motor screws out

Try to drip a little of WD-40 into the grab screw hole, and if it doesn't help warm it up, I use a soldering iron.

Got it thanks .. where is the best place to buy a 15 tooth pinion for the 3s

Any cheapo "American sold" pinion will do. You won't need anything hardened steel unless you're running a steel spur (big) gear. Just make sure it's the same pitch as your spur gear, which I believe the stock is 32p. Also make sure the hole diameter matches your shaft, which I believe is 3mm (anything around 3mm will do, just don't buy a 5mm or 8mm)

 

[Yonic]

The pitch is indeed 32p, but the shaft is 5mm.

 

[DoNoHarm]

Thanks for the correction! Whoops. Yeah just get a 5mm diameter shaft with 32p and 15t.

Thanks guys

Just curious but why a 15T?
Why not use the 16T Arrma one as supplied with the Typhon 6s? (part number AR310477)

As suggested heat is your best bet for easy removal. Hold a soldering iron on the motor shaft for quite some time so that it can help break down the Loctite.

Worst case scenario you can buy a pinion gear removal tool from Hobbyking. You shouldn't need it but it is an option.

Did u get the pinion off?

 

[GMballistic]

@Wags1 I'm guessing you meant that question for @MJMARLOWE .

I've removed several different pinion gears on my Typhon, used heat to aid removal the first time.

Sorry man.

Did u get pinion off yet?

 

[MJMARLOWE]

Yep all good thanks for the help just needed a little heat

Wish I would have seen this before I tried to remove mine. Now I have a stripped pinion grub screw!

I am have some bad luck recently ?

when you buy a new pinion, it should come with a new grub screw.

Yeah but it's the getting the old one off that he's upset about.

Drill it out. Use a slightly smaller drill bit and carefully drill it out.

 

[TurboTeg512]

i agree with Wags1 on that. ive used a Dremel too, just make an X pattern
