Bottom pulley removal

[Oortam]

I am working on an engine to replace the knackered engine in our rev 2. The replacement engine (rev 3)is in the garage getting tidied up before we fit it in the car. I'm going to replace the timing belt but am stumped how to get the bottom pulley off. The gearbox is off the engine, sio how do I lock the crank shaft to allow me to undo the bolt on the pulley? Any suggestions are welcome.

Flywheel lock tool and impact gun.

Just make up an SST like the Toyota one and brace it whilst undoing bolt.

I don't have a flywheel lock tool. Where do I find what the Toyota SST looks like and I'll try and make one. I'm guessing it locks against the ring gear.

Thanks for that. I'll get making some tools.

I simply stuck a screwdriver in the bottom of the flywheel and undid it with a impact gun.

As pete said i used a dewalt 18v impact gun to remove centre bolt( it took four fully charged batteries)
Made this to remove the pully

Just to update. I used a crowbar to lock the flywheel ring gear and then a socket on the pulley bolt with a bar. I then used a heavy hammer to shock the bolt and it worked. I then used a bar with two holes matching the threaded holes in the pulley with two bolts to jack the pulley off, similar to the previous picture.
