Husqvarna Clutch Cover Assembly Problem
Husqvarna Clutch Cover
When I removed the chain cover (clutch cover) it was extremely hard to get back on because of the middle ring (chain brake band) on the inside of the cover. I've tried everything and can't figure it out?
The problem your describing sounds like the chain brake band is engaged on the clutch cover. The clutch cover is the plastic cover that goes over the chain and sprocket area on your Husqvarna chain saw.
I believe the chain brake on the cover is engaged which will not allow the chain brake to fit back over the clutch drum. The chain brake band is the round metal ring inside the clutch cover. Once engaged, the ring reduces in size creating a binding effect over the clutch drum which is what stops the chain (safety feature).
To test this solution I pushed the front hand guard forward on my own saw while removing the clutch cover. This engaged the chain brake. When I attempted to put the cover back on it would not fit.
To fit the cover back on to the saw the chain brake band (metal ring) needs to be disengaged, making the ring bigger so it will slide back over the clutch drum.
The chain brake is engaged when the hand guard is pulled back which rotates a small, quarter sized y shaped piece of metal located on the top portion of the clutch cover. It looks kind of like a small propeller. To find this piece, turn the clutch cover over so you can
see the chain brake (metal ring) and look towards the top. You should see the small metal y shaped piece I'm talking about.
If you turn the metal piece to the right (clockwise) it will disengage the chain brake. I tried to do this with my own saw using a pair of pliers and found the metal piece was very hard to turn due to the tension.
To make it easer, align the metal y with the slotted piece on the hand guard. Once the y shaped metal piece is aligned in the hand guard slot, you can pull the hand guard back (towards the handle of the saw) and it will rotate the metal y clockwise, disengaging the chain brake. It's a little tough to do, but I tried it twice with my saw and it worked both times. Just make sure to align both pieces so you don't strip or break anything.
Once the chain brake is released you can easily slide the clutch cover back on the saw for reassembly.
Use an air compressor to blow away any sawdust and wood debris inside the clutch cover. Sometimes the saw dust will pack in around the chain brake causing it to constrict a little, which could also cause it to bind on the clutch drum.
I included the picture to help identify the parts and hopefully make the process a little easier for you.
Also make sure to wear a pair of protective gloves during the process.
I hope this helps!
