+ 1 what token said but I use the OS piston lock and it works great. I wouldn't use anything else but to remove the flywheel from any engine. It's cheap, SAFE and very easy to do, just remove the back plate slide in the tool and remove the flywheel nut and you done.

Pliers and a rag is all you need to remove the flywheel. All the other stuff is marketing hipe. Its a simple procedure to say the least.

If you want to lock the piston, you can use oil. Just put in the glow plug hole and screw the plug in. That way it distributs the pressure evenly. I don't like using the rod and wrist pin to lock a crank, but it can be done. Wait until you break a piston skirt or puch a hole through the top of a piston. You wont do that again...

no no


take out the carb and stick something not metal( i use the end of a toothbrush ) in the intake of the crank


that tool should work great , i just dont like to put any undue stress on any of the components that rotate and play a vital role to the engine running properly

Channell locks and a deep socket seem to work fine for me to get the nut off on my 8ight flywheel. But to actually get the flywheel off I put it in the vice with a rag and gently wiggle it off. After reading this thread I'm thinking I need a flywheel puller tool though. Do you guys think the way I'm doing it could damage something?

channel locks with a peice of cardboard to protect the flywheel works fine for me too. I just tap the back of the flywheel with a screwdriver that has a plastic handle and it pops right off.

That is the point of using a zip tie. It will break before it puts too much stress on the engine. I only use it to get the nut tight enough to where the flywheel won't rotate on the collet. Then I hold the flywheel with channel locks(if a losi flywheel a creascent wrench) to get it tight. And when removing the nut, I will only use a zip tie after I get it slightly loose(again with the channel locks or wrench). I have never damaged an engine doing it this way for several years.

I like the looks of that tool, but it would be a pain to have to remove the backplate every time you want to change a flywheel out. Especially if you use carb sealant on the backplate. I would not have a problem using one of those tools, but STAY AWAY from the piston lockers that thread into the glow plug hole. They WILL hurt your engine.

Pliers and a rag or cardboard only work when the flywheel is locked on the collet. If the nut has loctite on it or it is just tight and the flywheel comes of the collet the pliers and rag won't work.
