I cannot get the clutch cover off my husqvarna 455

SOURCE: how do i remove the cluth drun on a husqvarna 455

Hi, first take off the clutch cover by removing the two bar nuts.
The nut on the clutch is left hand thread. You need to have some sort of piston stop to bind the engine when you remove the nut. They make tools just for that( it's called a piston stop) but I like using a small piece of rope. Just take out the spark plug, run a bit of the rope down in the cylinder and that will hold the piston really well. You could use a lof of things for that, I would be careful that it's something that won't gouge or mess up the top of the piston though. When you have that done you can remove the nut holding the clutch assembly on and remove the drum. ( REMEMBER that left hand thread ) Hope that helps you.

Why would you pay for something and then not force them to make good? I have a large bridge for sale, CHEAP. Make you a heck of a deal.
Take it back!!!

http://weborder.husqvarna.com/order_static/doc/usa/2006/I06000/I0601076.pdf
See Detail A, pn 503 89 08-02. You can use a Crescent Wrench on one of the ears (left end) to reset it. With the cover positioned with pn 503 89 08-02 in the upper left rotate it CW until it nests, to reset it.

This works quite well:

If you do not have a vise a large C clamp to a work surface might work, you may still need a block or two of wood.

You can download the IPL for you saw here:

Enter the 3 digit model number (no XPs, Es, just the numbers)
Serial number decode – useful when downloading IPLs and Manuals
06 1500198
06 = year produced – 2006 (single digit before 2000)
15 = week produced - March
00198 = 198th unit Husky produced that week

I will wager you will NEVER again remove the cover with the brake set. Me either! Good Luck. HTH

Ignition module gap
Place a business or index card between the fly wheel and coil, rotate until the magnetic attraction pulls everything tight together. Tighten the coil screws, rotate the flywheel until the attraction eases and remove the card. Ensure nothing contacts when flywheel is rotated.

SOURCE: CHAINSAW BRAKE LOCKED ON HUSQVARNA 455 RANCHER HELP PLEASE?

I used applman08's solution. A few pointers:
0. This problem occurs when you take off the side cover while the brake is set. So after you fix this, don't do that again.
1. When removing the clutch, place the screwdriver in the notch next to where it says "off" and tilt the screwdriver down so that when you strike it you are applying a clockwise shock force that is almost horizontal (assuming your 455 is on its side).
2. DO NOT remove the spring! There is a plastic housing that basically holds the brake mechanism in place (secured by 4 screws). If you take that apart, and then take out the spring, you will be learning how the brake works and spending some time compressing that spring and getting it back in. You'll have to come up with something clever to get the spring in depending on tools available.
3. Going back to 1. - get that clutch off, put the side cover back on, getting that brake lever lined up with the very-difficult-to-grab three-toothed mechanism for engaging the spring. Tighten down the side cover, or hold it snug with one hand while you lever the brake handle with the other. You will hear a satisfying snap as the braking mechanism (with the spring I told you not to mess with) resets.
Note: You can probably reset the braking mechanism by manually turning that three toothed gizmo but it's really hard to grab and the brake handle fits it perfectly. The key is you've got to turn that about 60 degrees.
Good luck, this was an annoying problem.
