Failed to set brake properly before removing chainsaw cover
Read carefully the owner's manual procedure for removing cover BEFORE removing cover from chainsaw! Or, watch you tube video for proper procedure--it would have saved me from needing this replacement part. Not having done either, after prying the cover off to get at the actual chain saw, it became quite obvious that the cover was not going to back in place without some tool to reset the safety brake which had not been properly set before disassembly. Brute force was not the answer. Broke the plastic spring guide ( aka knee joint) in several attempts to force said spring back in place. Frustration led to you tube videos in what not to do and what one should do. Improvised sprocket to reset the brake and used the replacement knee joint to effect the repair. Took 20 minutes to make the tool, and five minutes to put the assembly back together.

Chain brake broke
Removed the old parts and installed the new parts. Very easy job to complete.
The hardest part was putting the spring in place. To compress the spring , I used a medium sized flat screw driver and placed it in the end of the spring so it screw driver went part way in the spring and the wider part was able to push on the spring and with my other hand, hold down the rest of the spring and components and pop the spring in place.

Question: Husqvarna Rancher 455

Do you have the tool for resetting the knee joint after replacing the spring. The chain break band is compressed and the clutch cover will not go back on.

Hello elfs,

We have an article and video that I hope will help you with your repair. Here is a link to it.

How to Install a Locked Chainsaw Sprocket Plate

Hope this helps,
-WJA
I had the same problem w/ installation. I could not get the spring to compress AND fit the joint into the clutch cover. The first one broke while installation. Instead of breaking a second piece I took it to a small engine repair shop. It took two men about 30 min to install it. I saved big money by purchasing it from ereplacement parts because the shop was going to charge me double the price offered by ereplacments. But they had the manpower and compression tool.
