Re: fly wheel seemds locked up on Husqvarna 445
The flywheel does not have a brake,the clutch side has the break.if you have the chain side cover off the brake is no longer on the clutch drum.the fly wheel is on the oppiset side (starter rewind).take the starter rewind off and see if the motor will turn.if hte motor turns the problem is in the clutch side.if it doesn't the problem is in the flywheel side.the ignition coil has been known to loosen up.the screws streitch out from heat.check the air gap between the flywheel magnets and the ignition coil.should be .10 to .12 inches.if problem is on clutch side check to make sure that the springs are on between the clutch discs.they have been known to break and that does not let the chain spin on bar.any questions get me an e mail
Firstly, try pulling the chain brake handle back into the running position - you should hear a click if the brake is working correctly. Then try rotating the chain by hand - if it rotates your problem is solved!
If this does not work you should check to see that the chain brake cover is seated properly on the saw. You may be binding the clutch with the chain brake. Remove the chain brake or clutch cover again and attempt to reset the brake by pulling it to the rear - again you should hear a click. Reinstall the cover and ensure it is seating flat to the main body of the saw. Then ensure the chain is loose enough to rotate by using the chain tensioning screw - the nut or nuts that hold the chain brake to the saw will have to be slightly loose. The chain should have a very minor bow to it when you look at the bottom of the bar. Do not forget to snug the nuts down firmly when your a finished.
Should these suggestions fail you might consider going to your chain saw shop and have them look at it as the chain brake is an important safety item and should function correctly at all times.

Not an easy thing to reset either. You can try putting chain brake back on with the retaining nut(s) loose so don't go flying. Now place the reset handle as far forward it will go. While pressing hard with hand at the chain reset location of the cover pull back on the reset handle. This should reset the brake.
Note this will not always work and sometimes you need a saw shop to help reset it.
If this is the tooless system, flip open the wing on the bar cover securing nut, slacken off one turn, now use the knurled wheel in the cove to slacken, or tighten the chain, if it has two 13mm bar nuts, slacken them off one turn each, then use a flat blade screw driver through the side cover, betwwen the bar nuts to adjust the chain, the screw is quite small so clean away the saw dust to locate it.
The two halfs of the rear handle do not seperate, once you have removed the r/h side grip you can remove the throttle lock, you then need to remove the pivot pin from the trigger with a pin punch, the trigger can then be pulled down and out, you may need to disconnect the throttle wire from the carb if you cannot drop the trigger far enough to remove the wire from it.
Verify you have oil in the oil fill tank. Try cleaning inside the drive sprocket cover. Release the chain tension and carefully dislodge the bar and chain assembly. Clean sawdust and debris from behind and inside the housing and behind the bar. Use a wisker wire to clean the through ports and channels on bar( these ports are the path that the oil travels to the drag groove that the drive links on the chain uses to pull the oil to the tip of the bar).

If this does not correct the problem contact Husqvarna customer service or a local service repair.
The problem you are experiencing is very common. Many people remove the side cover with the chain brake applied or either the brake becomes engaged after the cover has been removed. You will need to reset the brake before you can install it. This is a little tricky but can be accomplished. I find that it is done fairly easy by carefully clamping the side cover in a vise, and using a good strong pair of needle nose, span the "rotator" (star shaped wheel) on the brake and with another pair of pliers, grab the needle nose pliers and "twist" the brake into the disengaged position. Hope this is explained well enough to get the job done.

It includes a good illustration of the brake and its' components. It is likely the chain brake is released and will need to be engaged to enlarge the brake band. Reset Chain Brake Immobilize the clutch cover (blocks of wood on a flat surface to protect the finish) in a vise or with a large C-clamp to a work surface.
Use pliers or a crescent wrench and rotate it clockwise until it latches open. This will require some force. A slight modification reported in a testimonial to the above method follows; " Thanks for the help. I took your answer and modified the fix a little. I placed the cover on loosely and then moved the bar handle into the right position in order to engage the spoked wheel, then rotated the handle back until the cover fit right.

A model number would have been helpful. I suggest a length of nylon rope (nothing left behind) be used as a piston stop (retain 6" ± so you can remove it). Make sure the piston is near the top of the cylinder before feeding the cord or it can fall through the exhaust port and damage the piston as it rises Some pry them off (breaks cases, may damage points on yours), some smack the crank with a hammer (your crank), Some try holding the fly wheel and break cooling fins that effect balance. Professionals use a puller (call a local saw shop they might do it for a small compensation). HTH Lou
