Fireteam Third time pinion flew off

[abh16]

Anything besides loctite the grub to keep pinion gear on? My fireteam lost its gear three times this past 2 weeks. Is the clip even doing anything that's gone too.

MIP hex drivers thread lock and crank it down and let it sit for 24 hrs. Make sure your threads on the grub screw are clean from old TL first
My exb pinion kept falling off till I did this then never again. The 2.0mm & 2.5mm MIP hex drivers are mostly all your gunna need

I had this problem with my xmaxx..wouldn't stay on for nothing.. I agree with @Alan Make sure the grub and pinion are completely cleaned of old thread locker. 24 hour cure time. It's been working for a couple weeks without coming loose. Good luck

How you CLean off loctite....with a Degreaser?

To add on to what everyone else said, make sure your gear mesh is not too tight.

I had this problem. I personally don’t like the stock gears. My mesh was good, grub and threads were clean, used loctite, and still had issues after awhile. Slapped on a Robinson gear and haven’t had a problem since. This is on my Outcast 6s EXB.

I've switched to Tekno gears as they use a larger set screw. Even then I use isopropyl alcohol to clean them first. If its a used gear that has seen locktite a couple time I will get them warm with a mini torch and burn it off. Then clean the residue with alcohol. Always let it sit for 24 hours otherwise it's going to come loose.

Their gears require a 2.5 driver right?

2.5 or 3, I can remember but the actual bit size but it's an M5 set screw.

Nice. I'm gonna make the switch for my bashers at some point for that reason alone.

Yessir, 2.5mm driver it is for Tekno pinions. I recently replaced all of my M5 grub screws with Torx® grubs and they have just been excellent. Can recommend.

I'll see if they make them in Torx plus. I believe I have drivers in that size. Torx plus is the best thing since beer.

Took me a bit of searching to find M5 Torx grub screws so if it's of any help, mine are made by FG. It doesn't say Torx plus specifically, but I've been exceedingly happy with these.

6930/05 FG Grub screw with Torx M5x5mm - 15pcs.

I'll check em out. Thanks. Torx plus is the same thing except the star edges are rounded giving more bite.

I use my mini torch, a wire brush, and a pair of needle nose pliers to hold the screw.
DON'T lay the hot screw on the wooden dining room table!
DON'T lay the hot screw on a good towel (Also, DON'T use a good towel for anything RC)!
DON'T lay the hot screw on the carpet!

I also use Robinson Racing pinions and as of today are now on all three rigs, no more stock pinions or grubs for me.

I feel like you are speaking a little bit from experience here

You would be correct! Although this was one incident, the hot screw was on the towel to start, then the table and finally on the floor.

My Tekno pinions have a 5mm grub screw with a 2.5mm socket. I’ve never felt the need to go to Torx grubs because I’ve never had issues with them coming loose.
