How to Remove Fly Wheel Weight

Recommended Posts

Replacing cam chain and don’t have the tool to remove fly wheel weight. Anybody have any good ideas to remove it without the tool?

The piston stop to prevent rotation or, the 'spanner' to unscrew the FWW?

Post a pic.

If it's like the other Gnarly FWW I've seen, those 2 threaded holes are SAE 1/4-20 thread pitch.

Measure center to center of those hole,

take a flat bar length of metal about 12" to 18" long

drill two 1/4 holes at the required distance and bolt it on the FWW to use as a leverage arm.

 

Don't forget to first back out the set screws along the outer edge of the FWW.

 

Commonly the tool supplied is a piece of flat bar with 2 holes (as per above)

but with a 3/8" square drive in the center to insert a torque wrench.

I'd add, measure the thickness of the flywheel in the bolt holes,

don't use bolts that are too long and might damage anything behind the FWW, add washer if required.

Alright. Will the torque of the tool alone be able to take it off or will the flywheel still spin?

You will still need to lock the engine from turning,

try with the gearbox in 5th gear and someone holding the rear brake on.

Is there any other way of doing this? The engine is currently on workbench

Put a piece of rope through the spark plug hole, or buy the Tusk engine lock up tool for about $10.

Just put a long bolt through the spark plug hole with the same threads as your spark plug. No ordering or waiting to get it.

A soft polypropylene rope fed into the cylinder at the bottom of the compression stroke will safely lock the engine.   Sorry Joe, I would never recommend using a bolt through the spark plug to freeze the piston.  Way too much chance for a catastrophic accident.

A steering wheel puller ?  :facepalm:   The weight is threaded in place , not a press fit.  It must be rotated to unscrew it.  A bolt will do the same thing as the lock up tool.

I'd be very careful about putting rope down the spark plug because you could bend the valves.  Make sure you're doing it on a compression stroke.

To lock the engine from rotation, you can lock up the counterbalancer (just to the front of the flywheel) with this simple procedure- insert a hex wrench into the socket head cap screw which is under the counterbalancer. 

Hope this helps.
