For the flywheel on the 3400.
I stick a wood wedge between the case and the flywheel and then use a piece of hardwood and a hammer the smack the flywheel on the off magnet side (not on the magnets). Not much pressure with the wood wedge, just a bit. It will come eventually. Patience, and don't get ham fisted.
Some good info here on chain types, pitch, gauge, bars, etc. Well worth the read.
