You what a loctite to hold your pinion gear for good try some green loctite
it will be for good! blue and red gets soft when hot, green can withstand the heat, not blue or red.

P.S. sorry for the spelling or the grammar I am dyslexic!

I have had a 450 that I used red loctite and it backed out within 45 flights. Now the motor didn't have a flat spot.

So in my opinion, I would say it's better to have a flat spot and use blue loctite.

- torque is what tightens the set screw
- loctite is what keeps it from backing out
- flat spot will jam it tight
- I have done that on all my heli ever since and it's worked well for me.

according to the data sheet from loctite, I found out that it sometimes takes 48-72 hrs for the loctite to fully cure. even Ron from Ronlund.com suggested this too.

I used to fly within an hour or let it sit over night ... LOL

red and blue are threadlockers.

you want green ....the sleeve retainer. Let it set for at least 8 hours, too.

if it ain't broke, break it.

If the set screw with red thread locker is on a flat on the motor shaft and is firmly torqued with a good tool, the pinion won't move. If you use sleeve retainer, it'll make future service a giant PITA.

well, if there's a set screw I never use any threadlocker or sleeve retainer. I assumed (I guess wrongly) that he was asking about a press-fit pinion.

if it ain't broke, break it.

If the set screw is bad or the threads are worn on the pinion, re-tap it and use a set screw one size up. You can buy a tap at orchard hardware or home depot etc, as well as set screws, then use blue loctite.

Wc,

Remove pinion, remove grub screw, get a quality grub screw replacement, check the grub screw is a good thread fit in the pinion with minimum slop.
Clean and degrease pinion and grub screw.
Ensure there is a decent flat on motor shaft if in doubt bag up the motor, and put a decent flat on it.

Refit motor, and when your ready....

Degrease pinion and grub screw again, allow to dry completely and apply red or green loctite either will be more than adequate. Refit pinion and do not remove it again, re adjust mesh, then leave the loctite 24 hrs before flight.

Check your loctite is fresh as well and use quality branded loctite if that does not hold you have other problems going on somewhere else, and they will need looking at.

Good luck

Loctite now comes with a use before date, I don't take much notice of it either, but at 8 years it may be time for new.

red has held good for me even on gassers.

Good luck

+1 for the green. You need the right stuff for the application. Green is the one for this application.

nothing a torch can't burn off.

wc, you could put red on the shaft and a little inside the pinion, side them together and wipe off the excess as you tighten the grab/set screw. It's always better to have a flat spot like a keyway on larger motors.

My original Align 450 dfc hub doesn't have the split lock below the jesus bolt. The first time I put the hub on the shaft I smeared blue loctite on the shaft and in the hub. When it came time to separate the two parts sometime later I had to heat the shaft, put it in a vice, and grab the hub with pliers while twisting to remove it from the shaft. I'm still using the hub this way, it was very tough to separate the two parts so I'm fully confident they are held so good the jesus bolt could fall out and nothing happen. The same enhanced method of retention should work for the pinion problem.

Heat will indeed soften JB Weld right up just like it will any epoxy.

If that locktite is 8 years old and you are using it ,you are asking for a disaster. I used and old bottle of the blue at one time and paid the price for it in the long run. The bottle of locktite is only good for about a year. buy the smallest bottle you can get your hands on, so you use it up before the date expires.

Nobody seems to have mentioned this, but I don't really want to put anything together permanently. The red loctite is as far as I go. I want to be able to service parts if I need to.

I have never had a pinion grub screw come loose. A proper flat spot, some red and tighten to a firm tight. No reason to bear down on these screws. Let the chemical do it's job.

If I need to take it apart, I use a soldering iron or small butane torch to heat it up.

I like Aligns idea of 2 grub screw at 90 degrees to each other. You do have to dremel the second flat on the motor shaft in most cases but once done, blue loctite is all you need.

60% of the time, it works every time!

There are two types of green. One as stated is a shaft/sleeve retaining compound 609.

The other green is for threads but you added to the threads after u torque it down its a penetrating locker. Will loosen with a good amount of heat.

Edit 290 is the green penetrating
220 is blue penetrating

Torches have no place for helis.

Blue is more than sufficient....applied sparingly.

290 can be loosened with soldering iron with old tip & a good tool
