Removing Flywheel?

[Red Winger]

How do you remove a flywheel without the right size nut driver? Do I have to have the nut driver or can I use pliers?

I guess you could use pliers, but I would not recommend it. I like to use an open-end wrench. If you use something other than a nut driver, be sure to be careful not to bend or break your clutch shoe pegs.

You will also want to use a piston locking tool, if you don't have one. They are inexpensive and can be found at most hobby shops.

What would the piston locking tool be for and what does it look like?

A crankshaft locking tool would be better.
Piston locking tools get screwed into the glow plug hole in the cooling head. The part that goes into the engine rests on top of the piston as you crank the nut down; preventing the piston from moving. They may cause a bushing to deform, a pin or rod to bend, or break something.
Crankshaft locking tools go below the sleeve, and prevent the crankshaft from spinning, by disallowing movement of the con rod.

You could use pliers, but it's very hard to torque a nut with pliers. It would be better to go to a hardware store, and spend $2 on a 10mm deep socket (TRX 2.5 requires an 8mm deep socket). to use with a socket wrench.
