Super Jet Any way to remove coupler from crank that is not in the engine?

[fals3illusion]

So kinda made a mistake today, took apart my engine and forgot that when I have to replace the seals I have to remove the coupler from the crank.... any way to get this coupler off without rebuilding the engine again so the crank doesn't move?

Thanks!

Easiest way would be to just bolt it back into the cases, throw a piston on the rear shaft, throw the cylinder and head on and use the rope trick. Take you about 10 minutes if your slow. dont have to use every bolt.

kinda figured thats what i had to do, wasn't sure if there was an alternative ! Always took me forever to get the pistons in the cylinder ha ha so may take me longer! Thanks

Take the rings off.

Heat the coupler up. Set it on clean rag and hit it with a rubber hammer in a ccw direction while holding crank by hand at web. Never had any trouble getting it off this way and you dont have to get it very hot either. Never damaged one.

ill give this a shot at work today. And if not ill just rebuild and do the rope trick

Clamp crank web in vice and spin coupler off.

This is what I've done.

Yes, clamp the crank in a vice using the counterweight and let it rest at the bottom of the vice as well. Grab a 2x4 and set it on a coupler finger and whack the 2x4 with a hammer to break it loose. Works easier than doing it with engine assembled

Wait, is everyone just assuming he doenst have a cold fusion flywheel lock? Thats the easiest way, flywheel lock and a 2x4.

His crank is already out of the cases........

He took the engine apart then realized coupler still on

He pulled one of those "What the hell did I just do" moments that we have all done before.

I once pulled motor completely out to change out the rubber dampner in the coupler....... Was not thinking.

Nice to know there is another way!

The vice option works.. Just did it, use a brass hammer to tap coupler off
