Guys me and my son are having trouble keeping the flywheel locked down on my nb and his nt. I used blue loktite and they still came loose. do you have to use a crank stopper to get them not to come loose?

Stop using blue threadlock coming with kit. And make sure everything else is ok: bearings, flywheel gap etc.

I had that problem desertracer. I ended up getting a pair of channel locks and a socket wrench and put some muscle on it. Hasn't some loose since.

the nut is the same size as your glow plug so you can use that driver.

I use a set of multi grips on the flywheel and just do it up as tight as you can it is just about holding the fly wheel tight while doing up the nut.

Thanks guys..

If you do use locktite, make sure you get both the crank and nut threads super clean. Any dirt, oil, or dried locktite will compromise the thread lock.

Those glow plug wrenches are cast and not machined. So the metal will split rather easily. I'd invest in a 1/4" socket wrench and a 10mm socket to use specifically for flywheel work. And I use a small pair of slip joint pliers to hold the fly wheel.

But I know there are specific flywheel tools that come from the R.C. industry.

10mm? The nut is 8mm. Get a 8mm T-handle and crank it down as hard as you can.

Oh my bad. Been a while since i've had to tear down an engine.

Hi,

This may be due to the brass flywheel collet collapsing before it can get tight on the crankshaft. The little slot on the collet is probably not wide enough. You have two options - 1. grab a dremel and a cutting wheel and make the slot wider or 2. contact our customer support and we can send out a flywheel collet with a wider slot.

For anyone else having weird engine issues (i.e. running hot, clutch feels like it's slipping, clutch assembly coming loose), the flywheel collet may be the issue. Please take a look at the collet and if it appears that the flywheel is slipping, make the slot in the collet wider.

I had the same problem. I lost two engines due to over revving. I was pissed. I founded out the nut was coming a loose from the fly wheel causing this problem. I now loctie that nut. The problem seems to have stopped

this is what i use and have no problems in any way with the flywheel… Great flywheel tool
